Executive Summary<br />
The Cooper Basin is located 800 km north of Adelaide in a remote, sparsely populated desert environment. The Cooper region<br />
has been under licence continuously since 1954 and is currently held by Santos and partners – PELs 5 & 6 cover 67 000 km 2 .<br />
Since 1954, Santos and joint venture partners have drilled over 1200 exploration, appraisal and development wells. At 30<br />
September 1997, 85 gas fields with a total of 354 gas wells were on line and a combined total of 190 PJ (150 Bcf) of sales gas<br />
was sold in that year to market in SA and NSW. At 30 November 1997, 28 oil fields with a total of 118 oil wells were on line<br />
and approximately 0.6 million kL (3.8 mmbbl) of crude oil, 0.4 million kL (2.5 mmbbl) of condensate and 0.3 million tonnes of<br />
LPG were sold.<br />
On 28 February 1999, PELs 5&6 expire and the South Australian Government has decided that the Cooper Basin, exclusive of<br />
production (and potentially retention) tenements will be made available for competitive bidding. In order to facilitate this<br />
process, reviews of the legislative regime, data issues and a review of the necessity of access to existing processing plant and<br />
associated infrastructure have been conducted.<br />
The opening of the Cooper Basin to competitive bidding provides a unique opportunity for explorers. Advantages include<br />
established infrastructure and markets, proven play concepts, high wildcat discovery rates, access to detailed data and a<br />
government with a proven track record of facilitation of responsible petroleum exploration and development.<br />
The release of blocks CO98-A to K is the first in a phased acreage release in the Cooper Basin. The announcement of blocks<br />
before the expiry of PELs 5 & 6 is designed to ensure a smooth transition by minimising delays in new exploration in the<br />
Cooper Basin.<br />

<strong>EXPLORATION</strong> HISTORY<br />
The Cooper Basin forms the most significant element of<br />
Australia’s largest onshore oil and gas province (Fig. 1).<br />
Petroleum exploration commenced in the region in 1954<br />
with the granting of OEL 7 to R. Bristowe on behalf of<br />
Santos. Early exploration targeted the Cambro-Ordovician<br />
and in 1959 Innamincka 1 was drilled, following a<br />
reflection-refraction survey carried out over Innamincka<br />
Dome with Delhi Petroleum as operator. Additional<br />
reflection surveys over the ensuing years led to the discovery<br />
of gas in the Permian section in Gidgealpa 2 in 1963 and<br />
three years later the ‘giant’ Moomba gas field was<br />
discovered. One third of South Australia’s Cooper Basin<br />
gas reserves are in the Moomba and neighbouring Big Lake<br />
fields. The decision to generate the bulk of South Australia’s<br />
electricity from natural gas ensured the economic viability<br />
of constructing and operating the Moomba–Adelaide<br />
pipeline, and gas was first supplied to Adelaide in 1969.<br />
PELs 5 and 6 were granted to Delhi and Santos in 1969 to<br />
replace OELs 20 and 21. During 1973 an agreement was<br />
signed by the Cooper Basin Producers to supply gas for the<br />
New South Wales market and a pipeline was constructed<br />
linking Moomba and Sydney.<br />
The first Cooper Basin oil was discovered in Tirrawarra<br />
1 in 1970. The Tirrawarra field contains 80 per cent of<br />
known oil reserves in the SA region. Eromanga Basin oil<br />
was discovered in 1977 with an uneconomic flow from<br />
Poolowanna 1 (Poolowanna Trough) and the first economic<br />
oil flow was recorded from Strzelecki 3 in the following<br />
year. In order to market newly discovered oil and existing<br />
gas liquids, the Cooper Basin Liquids Project was initiated<br />
in 1980 and completed in stages from 1982 to 1984 at a cost<br />
of $1.4 billion. The project involved the construction of a<br />
high vapour pressure liquids pipeline from Moomba to a<br />
processing plant and storage and loading facilities at Port<br />
Bonython, as well as field development, oil collection and<br />
crude stabilisation facilities at Moomba.<br />
Shipments of crude oil and condensate commenced in<br />
1983 and LPG handling facilities were commissioned in<br />
July 1984. The establishment of these facilities enabled the<br />
Cooper Basin Producers to bring the wet gas reservoirs into<br />
production, which further enhanced production flexibility.<br />
In 1991 condensate production from Port Bonython was<br />
replaced by a full range naphtha, which has a greater market<br />
value.<br />
In 1991 a contract was signed for the sale of natural gas<br />
by the South–West Queensland Producers to South<br />
Australia. The gas is delivered to the South Australian<br />
market via a 190 km pipeline constructed by the Producers to<br />
link the Queensland gas fields with the Moomba processing<br />
facility and Moomba–Adelaide natural gas pipeline. An<br />
agreement was finalised between Santos on behalf of the<br />
Cooper Basin Producers and ICI in 1994 to supply ethane<br />
from Moomba to a petrochemical plant in Botany Bay. A<br />
pipeline was constructed and supply commenced in June<br />
1996.<br />
Since 1963, a total of 229 billion cubic metres (8.2 tcf) of<br />
recoverable raw gas and 6.9 million cubic metres (43.9<br />
million stocktank barrels) of recoverable oil have been<br />
discovered in the Cooper and Eromanga Basins in South<br />
Australia.<br />

GEOLOGICAL SUMMARY<br />
Eromanga Basin<br />
The Eromanga Basin covers one million square<br />
kilometres of central-eastern Australia and contains the<br />
multi-aquifer system of the Great Artesian Basin. It<br />
unconformably overlies the Cooper and Warburton Basins.<br />
Eromanga Basin stratigraphy can be divided into three<br />
sequences – lower non-marine, marine and upper<br />
non-marine (Fig. 2). Exploration is concentrated on the<br />
productive lower non-marine sequence.<br />
The lowermost unit of the Eromanga Basin is the Early to<br />
Middle Jurassic Poolowanna Formation, which consists of<br />
interbedded siltstone, sandstone and coal, deposited in high<br />
sinuosity fluvial and floodplain environments. Poolowanna<br />
Formation intertongues with and is overlain by low sinuosity<br />
fluvial deposits of the Hutton and Algebuckina Sandstones.<br />
Basinward lateral equivalents of the Algebuckina Sandstone<br />
are Hutton Sandstone, Birkhead Formation, Adori<br />
Sandstone, Westbourne Formation, Namur Sandstone and<br />
Murta Formation. The Hutton, Adori and Namur<br />
Sandstones are similar in lithology and facies to the<br />
Algebuckina but with an additional volcaniclastic<br />
component in minor amounts.<br />
Middle to Late Jurassic Birkhead Formation consists of<br />
interbedded siltstone, coal and sandstone, Westbourne<br />

Formation consists of interbedded siltstone and sandstone of<br />
Late Jurassic age. Murta Formation and McKinlay Member<br />
overlie and intertongue with the Namur Sandstone and<br />
consist of thinly interbedded siltstone, shale, sandstone<br />
deposited in a large lake which extended throughout the<br />
Cooper Basin region. The McKinlay Member is a lacustrine<br />
shoreface facies.<br />
Cadna-owie Formation records the transition into open<br />
marine conditions during the Early Cretaceous and consists<br />
of interbedded sandstone, siltstone and claystone with minor<br />
carbonate. The fluvio-deltaic Wyandra Sandstone Member<br />
is developed at the top of the Cadna-owie Formation. The<br />
contact between sandstones of the upper Cadna-owie<br />
Formation (Wyandra Sandstone Member) and overlying<br />
marine shales of the Bulldog Shale or Wallumbilla<br />
Formation approximates a prominent seismic reflector - the<br />
C horizon – which is mappable across the entire Eromanga<br />
Basin (Fig. 3). Formations of the Early Cretaceous (Aptian<br />
to Albian) are of secondary interest to petroleum exploration<br />
in the area and are not discussed in detail. The marine<br />
succession is overlain by the rapidly deposited upper<br />
non-marine sequence (Winton Formation) which consists of<br />
coal, floodplain and low sinuosity channel deposits.<br />
A period of erosion and deep weathering in the Late<br />
Cretaceous caused by a switch in drainage from the Cooper<br />
region to the Ceduna Depocentre on the rifted southern<br />
margin of the continent was followed by deposition of the<br />
non-marine Cainozoic Lake Eyre Basin. The modern<br />
landscape was formed during the Pliocene-Quaternary.<br />
Simpson Basin<br />
Non-marine Triassic sandstone, siltstone and shale of the<br />
Simpson Basin have been split into two formations. The<br />
Walkandi Formation is the older unit and consists of<br />
varicoloured interbedded shale, siltstone and minor<br />
sandstone. Pedogenic structures indicate fluctuation of the<br />
water table on a flood plain which was cut by high sinuosity<br />
fluvial channels. Walkandi Formation has been correlated<br />
with the Tinchoo Formation in the Cooper Basin, although<br />
Triassic palynological data are poor.<br />
Walkandi Formation is conformably overlain by Late<br />
Triassic Peera Peera Formation which consists of<br />
carbonaceous shale, coal and thin sandstone interbeds<br />
deposited in a high sinuosity fluvial environment. The Peera<br />
Peera Formation is correlated with the Cuddapan Formation<br />
in the Cooper Basin region based on well preserved,<br />
distinctive palynomorphs.<br />
Cooper Basin<br />
The intracratonic Cooper Basin represents a Late<br />
Carboniferous to Triassic depositional episode. It lies<br />
unconformably over early Palaeozoic sediments of the<br />
Warburton Basin and is overlain disconformably by the<br />
Eromanga Basin (Fig. 4). Three major troughs<br />
(Patchawarra, Nappamerri and Tenappera) are separated by<br />
structural ridges (Gidgealpa-Merrimelia-Innamincka (GMI)<br />
and Murteree) associated with the reactivation of<br />
northwest-directed thrust faults in the underlying Warburton<br />
Basin. These troughs contain up to 2500 m of<br />
Permo-Carboniferous to Triassic sedimentary fill overlain<br />
by as much as 1300 m of Jurassic to Tertiary cover.<br />

The Cooper Basin unconformably overlies Warburton<br />
Basin sediments. The Late Carboniferous to Early Permian<br />
formations comprise, in ascending order, the Merrimelia<br />
Formation and Tirrawarra Sandstone which comprise a<br />
glaciofluvial system deposited on glacially sculpted flat<br />
lying to deformed Warburton Basin sediments and volcanics<br />
and intrusives. The Tirrawarra Sandstone represents low<br />
sinuosity fluvial to proglacial outwash deposits overlain by<br />
peat swamp, floodplain and high sinuosity fluvial facies of<br />
the Patchawarra Formation.<br />
Two lacustrine shale units (Murteree and Roseneath<br />
Shales) with intervening fluvio-deltaic sediments (Epsilon<br />
and Daralingie Formations) were deposited during a phase<br />
of continued subsidence. Early Permian uplift led to erosion<br />
of the Daralingie Formation and underlying units from<br />
basement highs.<br />

Floodplain, peat swamp and high sinuosity fluvial facies<br />
of the Late Permian Toolachee Formation were deposited on<br />
the Daralingie unconformity surface and are overlain<br />
conformably by Late Permian to Early Triassic Arrabury<br />
Formation. The uppermost coal, approximating the top<br />
Permian is mapped as the ‘P’ seismic horizon (Fig. 5). The<br />
Arrabury Formation comprise floodplain and channel facies<br />
of the Callamurra, Paning and Wimma Sandstone Members,<br />
which are overlain by the Early Triassic Tinchoo Formation.<br />
In the northern Patchawarra Trough, the Cooper Basin is<br />
locally overlain by the Middle to Late Triassic Cuddapan<br />
Formation. Deposition in the region was terminated at the<br />
end of the Early Triassic with slight but widespread<br />
deformation, regional tilt and erosion.<br />
Warburton Basin<br />
The Cooper Basin is unconformably underlain by<br />
sediments and volcanics of the eastern Warburton Basin<br />
(Fig. 6). Warburton Basin sediments range from Cambrian<br />
to Ordovician; Devonian sediments have not been<br />
intersected in the Cooper Basin region of South Australia<br />
The eastern Warburton Basin is essentially a fold belt<br />
deformed during the Late Devonian-Carboniferous Alice<br />
Springs Orogeny intruded by mid-Carboniferous granitoids<br />
and subsequently buried to depths ranging from 1300 m to<br />
almost 4000 m.<br />
The eastern Warburton Basin contains a basal suite of<br />
acid-intermediate volcanics, tuff and agglomerate<br />
(Mooracoochie Volcanics), overlain by dolomitised shelfal<br />
limestone historically assigned to the basal Kalladeina<br />
Formation. A Middle to Late Cambrian carbonate shelf<br />
developed in the Coongie-Cuttapirie area, with a slope to the<br />
east. Several depositional sequences have been identified in<br />
the Kalladeina Formation typically with deep water shales<br />
overlain progressively by shallow water carbonate and<br />
clastic deposits. The Pando and Innamincka Formations<br />
continue this trend to shallow water depths as part of a<br />
deltaic complex with an extensive marine shelf sand. Black<br />
shale of the Dullingari Group with rare graptolites was<br />
deposited in the deep water Larapintine Sea which extended<br />
through the Warburton and Amadeus Basins to the Canning<br />
Basin.<br />
Middle to Late Ordovician shale and siltstone constitute<br />
the last preserved deposits of the eastern Warburton Basin.<br />
Early-Middle Carboniferous granitic intrusives (Big Lake<br />
Suite) beneath the Nappamerri and Wooloo Troughs were<br />
responsible for localised silicification and contact<br />
metamorphism of Cambrian country rock. A weathered<br />
zone up to 150 m thick has altered Warburton Basin strata<br />
and the granites in particular, immediately beneath the<br />
Cooper Basin unconformity. The unconformity at the top of<br />
the Warburton Basin is mapped as the ‘Z’ seismic horizon<br />
(Fig. 7).<br />
Structural style superimposed by compressional<br />
deformation during the Alice Springs Orogeny follows<br />
arcuate northeasterly trends imposed by northwest-directed<br />
thrust faults. Wrench fault zones have been mapped<br />
seismically in the Titan-Charo-Yanta area on the northwest<br />
flank of the Patchawarra Trough. Complex folding and<br />
faulting occur in some parts of the basin, but in many regions<br />
the Early Palaeozoic is almost flat lying.<br />

Reservoirs<br />
Eromanga Basin<br />
Principal reservoirs are good to excellent reservoir<br />
quality Hutton and Namur Sandstones (porosities up to 25%,<br />
permeability up to 2500 mD). Oil is also reservoired in fair<br />
to excellent quality sandstones in the Poolowanna and<br />
Birkhead Formations, McKinlay Member and Murta<br />
Formation. The Algebuckina Sandstone is a major artesian<br />
aquifer. The Cadna-owie Formation (Wyandra Sandstone<br />
Member) forms a significant oil reservoir in Queensland,<br />
however economic hydrocarbons have yet to be discovered<br />
in this unit within SA.<br />
Simpson Basin<br />
Sandstone beds within the Walkandi and Peera Peera<br />
Formation may form reservoirs in the eastern Simpson<br />
Basin. Where deeply buried in the Poolowanna Trough to<br />
the west, porosity and permeability have been severely<br />
reduced by silica overgrowths.<br />
Cooper Basin<br />
Multi-zone high sinuosity fluvial sandstones form poor<br />
to good quality reservoirs. The main gas reservoirs occur<br />
primarily within the Patchawarra Formation (porosities up<br />
to 23.8%, average 10.5% and permeability up to 2500 mD)<br />
and Toolachee Formation (porosities up to 25.3%, average<br />
12.4% and permeability up to 1995 mD). Shoreface and<br />
delta distributary sands of the Epsilon and Daralingie<br />
Formations are also important reservoirs. Oil is produced<br />

principally from low sinuosity fluvial sands within the<br />
Tirrawarra Sandstone (porosities up to 18.8%, average<br />
11.1% and permeability up to 329 mD). Towards the margin<br />
of the Cooper Basin, oil is also produced from the<br />
Patchawarra Formation.<br />
The Callamurra Member of the Arrabury Formation is<br />
conventionally regarded as a regional seal but nevertheless<br />
contains economic oil and gas reservoirs in some areas and is<br />
a leaky seal in others. Low sinuosity fluvial sandstones of<br />
the Paning and Wimma Sandstone Members form economic<br />
oil and gas reservoirs and high sinuosity fluvial sandstone of<br />
the Tinchoo Formation reservoir oil. As yet, there have been<br />
no economic oil or gas fields discovered in the Cuddapan<br />
Formation in South Australia.<br />
Warburton Basin<br />
Fractures in brittle siltstones (e.g. Dullingari Group in<br />
Lycosa 1) are capable of storing commercial oil and gas.<br />
Fracture patterns and their relation to pre-Cooper and<br />
post-Cooper Basin structure are currently being studied by<br />
PIRSA and NCPGG.<br />
Pando Formation sandstone has surprisingly high<br />
porosity (~10%) in view of its low stratigraphic position. It<br />
is glauconitic and zircon-rich and consequently has a high<br />
gamma ray response. Moolalla 1 gas is reservoired in this<br />
formation which extends from Pando in the west to Moomba<br />
in the northeast.<br />
Basal and middle Kalladeina Formation dolomites<br />
represent shelf limestones exposed to meteoric diagenesis<br />
during marine lowstands. Although minor gas shows have<br />
been recorded, porosity prediction has proved elusive, the<br />
dolomites and associated karst breccias proving tight when<br />
drilled.<br />
Sturt 6 oil was produced from weathered tuff which<br />
forms an extensive unit beneath the southwest Cooper<br />
Basin. The tuff, together with underlying agglomerate and<br />
lava, comprises the Mooracoochie Volcanics. Both the oil<br />
and gas originated from Permian source rocks.<br />
Source Rocks<br />
Both Cooper and Eromanaga Basin mature source rocks<br />
have actively contributed to oil accumulations in the region.<br />
Each oil accumulation needs to be considered on its merits<br />
with respect to the extent of ‘mixing’ from Permian and<br />
Mesozoic sources.<br />
Eromanga Basin<br />
Oil originated either in the Eromanga or the Cooper<br />
Basin or a mixture of both. Although it is recognised that<br />
Birkhead and Murta Formation sources exist, there is still<br />
considerable debate as to their extent and relative<br />
contribution.<br />
Potential source rocks of Jurassic and Early Cretaceous<br />
age contain Type II to Type III organic matter and have been<br />
shown to have maturities within the ‘oil window’ (onset of<br />
oil generation between vitrinite reflectance 0.65-0.7%).<br />
Significant suppression of Ro has been detected in some<br />
Eromanga Basin source rocks. Average TOC and pyrolysis<br />
yields are slightly lower for Eromanga source rocks<br />
compared to Permian source rocks. However, the Birkhead<br />
Formation contains the most hydrogen-rich organic matter<br />
and has an average TOC of 2.5% and S2 pyrolysis yield of<br />
12<br />
10.8 kg/tonne. The Poolowanna Formation shows fair to<br />
good source richness; the Westbourne Formation exhibits<br />
mainly fair source richness.<br />
Hydrocarbon extracts of Jurassic potential source rocks<br />
are paraffinic and waxy and similar to those from Permian<br />
sediments. This lack of distinction probably reflects only<br />
minor changes in organic facies and/or maturation histories<br />
or alternatively, reflects oil staining/contamination of<br />
Eromanga source rocks by migrating Permian<br />
hydrocarbons.<br />
Oils in Cretaceous reservoirs are often geochemically<br />
distinct from those in Jurassic reservoirs. They are typically<br />
light (45° API gravity), non-waxy, low sulphur, paraffinic<br />
crudes although waxy oils do occur. In Dullingari field,<br />
Murta Formation oils are thought to be locally sourced from<br />
Cretaceous source rocks.<br />
The marine Cretaceous sequence contains good potential<br />
source rocks, however it is considered immature for<br />
hydrocarbon generation. Clearly, more work needs to be<br />
done in order to distinguish local Eromanga Basin sourcing.<br />
Simpson Basin<br />
The Peera Peera Formation is rich in organic matter in<br />
the Poolowanna Trough to the west (TOC up to 5%) and is<br />
considered to be gas-prone, with modest oil generative<br />
potential.<br />
Cooper Basin<br />
Permian coal measures and shales are the principal<br />
hydrocarbon source rocks in the region and are dominated<br />
by Type III kerogens derived from higher plant<br />
assemblages. Oils and condensates are typically medium to<br />
light (30 to 60° API) and paraffinic, with low to high wax<br />
contents. Most Permian oils in Permian reservoirs contain<br />
significant dissolved gas and show no evidence of water<br />
washing. Gas composition is closely related to<br />
maturity/depth with drier gas occurring towards basin<br />
depocentres although there is strong geological control on<br />
hydrocarbon composition.<br />
The Patchawarra Trough contains the bulk of the oil and<br />
wet gas reserves consistent with local source rocks being in<br />
the ‘oil window’ while the hot Nappamerri Trough<br />
(40–50°C/km), underlain in part by granite, is overmature<br />
and contains mainly dry gas.<br />
Permian source rocks have average TOC and S2<br />
pyrolysis yields of 3.9% and 6.9 kg/tonne, respectively<br />
(excluding coals). Locally, the Toolachee Formation is the<br />
richest source unit. The Patchawarra Formation is<br />
considered the other major source unit especially the lower<br />
shales and coals. The lacustrine Murteree and Roseneath<br />
Shales appear to have little source potential.<br />
Together, the petrographic and geochemical evidence<br />
support coals and associated DOM as the effective source<br />
rocks capable of generating gas and minor oil, albeit in low<br />
yields. At maturity levels between 0.7-0.95% Ro, initial<br />
generation from the richer facies has led to partial filling of<br />
reservoirs with wet gas and oil. There is a sharp onset of<br />
significant hydrocarbon accumulation when the source<br />
reaches a maturity of 0.95% Ro.<br />
Thin, laterally discontinuous coals represent the best<br />
source rocks of the upper Nappamerri Group whilst shales
tend to be organically lean. Kerogen in formations of the<br />
lower Nappamerri Group tends to be oxidised and source<br />
rocks are humic-rich and gas-prone.<br />
Warburton Basin<br />
Source rock quality of samples principally from the<br />
Kalladeina Formation is poor to fair. With the exception of<br />
anomalously low maturity indices from Kalladeina 1, the<br />
succession below 3000 m is late-mature to post-mature for<br />
oil. Organic matter is mainly Type II kerogen derived from<br />
marine algal/bacterial precursors.<br />
Seals and Plays<br />
Where the regional seal is thin or absent multiple oil and<br />
gas pools are stacked in coaxial Permian-Mesozoic<br />
structures and may occur from as low as the Patchawarra<br />
Formation to as high as the Murta Formation. Locally,<br />
Permian oil has migrated into Warburton Basin reservoirs on<br />
the basin margin and gas has migrated into fractured<br />
Ordovician reservoirs fringing the Allunga Trough.<br />
Eromanga Basin<br />
Trapping mechanisms are dominantly structural<br />
(anticlines with four–way dip closure or drapes over<br />
pre-existing highs) with a stratigraphic component (e.g.<br />
Hutton–Birkhead transition, Poolowanna facies, McKinlay<br />
Member and Murta Formation). Eromanga structures in<br />
South Australia are rarely filled to spill with oil – net oil<br />
columns are relatively thin compared to the height under<br />
closure (due to poor sealing characteristics). Seals consist of<br />
intraformational siltstones and shales of the Poolowanna,<br />
Birkhead and Murta Formations – no economic<br />
hydrocarbons have been discovered in SA above the Murta<br />
Formation. Where these units are absent, potential seals<br />
include Bulldog Shale and Wallumbilla Formation.<br />
Cooper Basin<br />
Anticlinal and faulted anticlinal traps have been relied on<br />
as proven exploration targets but potential remains high for<br />
discoveries in stratigraphic and sub-unconformity traps,<br />
especially where the Permian sediments are truncated by the<br />
overlying Eromanga Basin succession. Economic oil and<br />
gas are reservoired in the Nappamerri Group, paradoxically<br />

regarded as a regional seal to the Cooper Basin.<br />
Intraformational shale and coal form local seals in the major<br />
reservoir units. Beneath the Daralingie Unconformity are<br />
two important early Permian regional seals - the Roseneath<br />
and Murteree Shales. The Roseneath Shale is the top seal of<br />
the Epsilon Formation and the Murteree Shale seals the<br />
Patchawarra Formation.<br />
Warburton Basin<br />
Cooper Basin reservoirs, source rocks and seals have<br />
been juxtaposed against elevated ridges of Warburton Basin<br />
rock by faulting or by original deposition. These ridges are<br />
potential lateral seals but may also be reservoirs. Ridges are<br />
composed of sandstone, shale, carbonate and volcanic units,<br />
which are fresh to severely altered by weathering and<br />
diagenesis (but not metamorphism). Dips vary from<br />
horizontal to vertical, and units range from massive to<br />
slightly to pervasively fractured, with weak to strong<br />
faulting and folding. Their competence as lateral seals is<br />
dependent upon a combination of lithologic and structural<br />
factors.<br />
Potential traps in the Warburton Basin include large<br />
hanging wall anticlines associated with northeasterly<br />
trending thrust faults and upthrown fault blocks on wrench<br />
fault zones.<br />
A thick impermeable weathered profile on the top<br />
Warburton unconformity surface forms a semi-regional seal<br />
and is distinguished on logs by its low uniform resistivity.<br />
UNDISCOVERED POTENTIAL<br />
Introduction<br />
The Cooper Basin is a mature petroleum province,<br />
however potential remains high for discoveries in<br />
stratigraphic and sub-unconformity traps, which have<br />
received increasing interest in the past five years. Pinchout<br />
plays along the margins of the Cooper Basin have been<br />
tested with commercial success. 3D seismic will have a<br />
critical role to play in delineating more subtle traps in the<br />
future.<br />
Remaining South Australian Cooper–Eromanga<br />
reserves estimated by Santos at 1 January 1997 were 2534 PJ<br />
of sales gas, 5.08 x 10 6 t of LPG, 5.61 x 10 6 kL of<br />
condensate, 5.33 x 10 6 kL of crude oil and 349 PJ of ethane.<br />
Undiscovered reserves of hydrocarbons have also been<br />
estimated by PIRSA, the Bureau of Resource Sciences<br />
(BRS) and Stratigraphic Research International AS<br />
(APRAS) to predict the undiscovered potential of the<br />
Cooper and Eromanga Basins. Results are summarised<br />
below. For more detail, refer to The Petroleum Geology of<br />
SA – Volume 4, Cooper Basin.<br />
Cooper Basin gas<br />
The present discovered recoverable raw gas reserves (as<br />
at 1/1/98) of the basin are 229 billion cubic metres (8.2 TCF)<br />
comprising 129 billion cubic metres (4.6 TCF) of produced<br />
gas and 101 billion cubic metres (3.6 TCF) of gas yet to be<br />
produced from known discoveries. The average recovery<br />
factor for gas fields is 64%. There have been 121 Cooper<br />
Basin gas fields discovered in South Australia to 1/1/98 from<br />

Cooper–Eromanga Basin oil<br />
The present recoverable oil reserves (as at 1/1/98) of the<br />
basin are 6.9 million cubic metres (43.9 MMSTB)<br />
comprising 4.6 million cubic metres (29.1 MMSTB) of<br />
produced oil and 2.3 million cubic metres (14.8 MMSTB) of<br />
oil yet to be produced from known discoveries. The<br />
combined average primary and secondary recovery factor<br />
for oil fields is 21%. More than 80% of the oil reserves are<br />
contained in the Tirrawarra Field. There have been 25<br />
Cooper oil fields discovered in South Australia up to 1/1/98<br />
from 297 new field wildcats. In the overlying Eromanga<br />
Basin, there have been 33 oil fields discovered from 293<br />
wildcats (to 1/1/93).<br />
Results<br />
Potential (undiscovered) resources should not be<br />
compared to traditional Proved, Probable and Possible<br />
reserves in known discoveries. Undiscovered resources are<br />
calculated to give a quantitative indication of the potential of<br />
the basin, and require considerable exploration to establish<br />
their existence. The results of methods considered to be<br />
reasonably reliable are summarised below.<br />

Some of the potential attributed to the Cooper Basin may<br />
have already been discovered in the Eromanga Basin. The<br />
current discovered recoverable oil reserves of the Eromanga<br />
Basin in the Cooper Basin region are 14.5 million cubic<br />
metres (92.5 mmstb).<br />
INFRASTRUCTURE AND MARKETS<br />
Production Facilities<br />
A total of 5090 km of pipeline have been laid to gas<br />
markets in SA and NSW and to the liquids load out facility at<br />
Port Bonython. Key pipelines are listed in Table 4 and<br />
shown on Figure 1.<br />
Gas emerges at the wellhead at pressures up to<br />
25000 kPa and temperatures up to 120°C. Gas from<br />
individual wells passes via field gathering systems<br />
(flowlines) to satellite stations which separate gas, free water<br />
and condensate. Evaporation ponds are used for water<br />
disposal. The essentially water-free gas and condensate pass<br />
to the Moomba treatment plant through trunklines. Crude<br />
oil is transported by either pipeline or truck to the Moomba<br />

operation in the Cooper and Eromanga Basins.<br />
Approximately 1010 km of trunklines and 1135 m of<br />
flowlines have been laid to date in the region.<br />
At the Moomba plant free condensate and water are<br />
initially removed from the raw gas at the slug catchers. The<br />
gas then proceeds to the Benfield unit to ensure that no<br />
greater than 3% by volume of CO2 remains in the sales gas<br />
stream. The gas is dehydrated at molecular sieves before it<br />
proceeds to the liquid recovery plant where 100% of the<br />
remaining condensate, 98% of the LPG (C3 and C4) and<br />
75% of the ethane are removed, leaving sales gas for<br />
Adelaide and Sydney with a heating value %.5 megajoules<br />
per cubic metre. The plant has been designed to process 25.4<br />
x 10 6 m 3 (902 mmcf) of raw gas and 6000 kL (42 000 bbl) of<br />
condensate and crude oil per day. Condensate, LPG, crude<br />
and some ethane are transported as a ‘cocktail’ via a pipeline<br />
to Port Bonython where they are separated and marketed.<br />
The feedstock delivered to Port Bonython is first<br />
sampled, filtered and metered to determine flow rates and<br />
composition. It is then pumped through a series of<br />
fractionating towers to separate ethane (which is used as fuel<br />
gas for the plant), propane, butane, light naphtha,<br />
intermediate naphtha, heavy naphtha, and reduced crude.<br />
Once cooled to ambient temperatures, the naphtha and<br />
reduced crude fractions are pumped to the blending section<br />
where they are mixed in precise ratios. The resulting two<br />
products, ‘naphtha’ and ‘crude oil’ are sent to storage tanks<br />
to await shipping.<br />
One destination for Cooper–Eromanga crude oil and<br />
condensate is the refinery at Port Stanvac, which supplies<br />
petroleum products mainly for the South Australian market.<br />
The refinery commenced operations in 1963 and the<br />
adjacent lubricating oil refinery began operations in 1976.<br />
The refinery does not have sufficient capacity to produce all<br />
the State’s requirements for motor spirit, and some must be<br />
imported from interstate. The main refinery products from<br />
Port Stanvac are LPG, solvents, motor gasoline, jet fuel,<br />
kerosene, diesel, lube oil base stocks for Australian and<br />
overseas markets, fuel oil and bitumen.<br />
Mini-refinery technology has proven itself viable in the<br />
Eromanga Basin at Eromanga in southwest Queensland,<br />
where the company, Inland Oil Refiners has been operating<br />
since 1985. The Eromanga mini refinery has a throughput<br />
capacity of 1500 barrels of crude per day and receives<br />
feedstock from a number of Eromanga Basin oil fields,<br />
including the Inland oilfield, discovered by the company in<br />
1994. The principal product is diesel, which is trucked<br />
across western Queensland to regional centres for<br />
marketing. Other products include automotive distillate, jet<br />
fuel, high quality kerosenes and specialised products for<br />
Mount Isa Mines. Heavy residues are processed in Brisbane.<br />
A mini-refinery located adjacent to the Port Bonython<br />
liquids plant produces 95 kL/day (600 bbl/day) of gasoline<br />
by refining naptha feedstock from the liquids plant. The<br />
mini-refinery supplies the northern Spencer Gulf region.<br />
Services in the Cooper Basin<br />
The northern part of South Australia is sparsely<br />
populated and relatively undeveloped due to its remoteness<br />
and harsh climate. The main primary industry in the region<br />
is cattle which are run on large pastoral leases. Eco-tourism<br />
is a growing industry in the region. The township of<br />
Innamincka is located 65 km from Moomba and offers a<br />
hotel, general store and light aircraft airstrip. The Birdsville<br />
and Strzelecki Tracks are unsealed, but provide access for<br />
heavy vehicle transport in the region.<br />
Accommodation and support facilities are located at<br />
Moomba, a fly in-fly out camp operated by the Cooper Basin<br />
Joint Venture. Access to these facilities is by arrangement<br />
with Santos Ltd. The Moomba Camp can accommodate 450<br />
people, with an additional 150 beds mothballed. A full range<br />
of support services is available at Moomba including<br />
logging, wireline, fraccing, cementing, transport, fuel<br />
supply, aviation and emergency services. The sealed airstrip<br />
is 1720 m long and able to accept medium-sized jets.<br />
Groundwater, extracted from the Great Artesian Basin<br />
aquifer system, is critical for petroleum operations in the<br />
region. There are two major aquifers, the lower occurs<br />
within the Algebuckina Sandstone and Cadna-owie<br />
Formation and provides hot (up to 100°C) good quality<br />
(TDS 1000 mg/l) artesian water. The upper aquifer<br />
comprises the Winton and Mackunda Formations and<br />
produces poorer quality water but is shallower.<br />
Markets<br />
A free market was introduced in 1988 for all oil and<br />
condensate produced in Australia. There is no restriction on<br />
imports or exports of crude oil or refined petroleum<br />
products. A similar regime has applied since 1991 for LPG.<br />
Markets for crude oil and condensate exist in South<br />
Australia and Australia and low sulphur light crude oils find<br />
a ready domestic and overseas market.<br />
Ex-field natural gas prices in SA are freely negotiated<br />
between buyer and seller. As a consequence of a gas reform<br />
process in Australia, regulatory policy impediments to the<br />
free trade in gas are being removed and the rights of access<br />
to gas transmission and reticulation pipelines have been<br />
provided, and direct negotiations between consumers and<br />
producers facilitated. The deliverability of a right of access<br />
to upstream facilities is also currently being reviewed.<br />
The Australian Gas Association study of future<br />
Australian gas supplies and demand forecasts that an<br />
Australian gas grid would be economic early next century.<br />
South Australia, with Moomba as a potential hub, is ideally<br />
placed to be a supplier to this grid when it eventuates.<br />
<strong>EXPLORATION</strong> ACCESS<br />
National Parks and Reserves<br />
A number of National Parks and Reserves have been<br />
created to conserve the best examples of vegetation and<br />
landforms in the region (Fig. 9). There are three types of<br />
South Australian reserves including Conservation Parks,<br />
National Parks and Regional Reserves. The conditions of<br />
access vary from park to park, based upon the type of reserve<br />
classification, the activity proposed and its likely impact on<br />
the environment. Access for petroleum exploration and<br />
production is allowed in all parks in the Cooper Basin region<br />
and in all regional reserves in the state. Access issues into<br />
the Coongie Lakes Control Zone are currently under review.<br />

Innamincka and Strzelecki Regional<br />
Reserves<br />
These Regional Reserves provide for the conservation of<br />
wildlife and the natural or historic features of the land while,<br />
at the same time, permitting use of its natural resources.<br />
Petroleum and mineral exploration activity may take place<br />
provided that they are subject to controls consistent with the<br />
management plan for the reserve (much of the production in<br />
the Cooper Basin is sourced from the Innamincka Regional<br />
Reserve).<br />
Part of Block CO98-E lies within the Innamincka<br />
Regional Reserve, and part of Blocks CO98- H, I, J and K lie<br />
within the Strzelecki Regional Reserve (Fig. 9).<br />
Mineral and petroleum exploration licence applications<br />
for areas within Regional Reserves are processed by PIRSA<br />
but are referred to the Minister for Environment, Heritage<br />
and Aboriginal Affairs (MEHAA) for comment.<br />
Exploration work programs are discussed with DEHAA<br />
(Department for Environment, Heritage and Aboriginal<br />
Affairs) as a matter of policy. In the case of production<br />
tenements, approval must be given by the MEHAA. Failing<br />
Ministerial agreement, the issue is referred to the Governor<br />
for decision.<br />
In all other respects exploration and production is carried<br />
out under the provisions of the Petroleum Act and<br />
Regulations.<br />
Parts of the Cooper Basin (Fig. 9) are listed as wetlands<br />
of international significance under the Ramsar Convention<br />
(the 1971 Convention on Wetlands of International<br />
Importance). The Coongie Lakes and part of the Coopers<br />
Creek system have also been included in the Register of the<br />
National Estate (Fig. 9).<br />
European heritage<br />
A number of sites of European heritage significance such<br />
as historic buildings and structures and geological<br />
monuments occur in the region. These are indicated on the<br />
Environmental Sensitivity Maps available from PIRSA.<br />
The majority of the sites are small and easily avoided by<br />
exploration activities.<br />
Aboriginal heritage<br />
In South Australia it is an offence to disturb or destroy<br />
Aboriginal sites, objects or remains. Standard procedures for<br />
determining the presence of Aboriginal heritage prior to the<br />
commencement of activities have been determined. These<br />
procedures involve consulting with the relevant Aboriginal<br />
organisation and maintaining a watch for sites, objects or<br />
remains during activities. Generally the sites are no larger<br />
than a few hundred square metres and are easily avoided.<br />
Since the inception of the Aboriginal Heritage Act in 1988,<br />
there have been no conflicts between Aboriginal heritage<br />
sites and exploration or production activities in South<br />
Australia.<br />
Commonwealth Native Title Act 1993<br />
The Native Title Act 1993 was passed by Federal<br />
Parliament on 22 December 1993. The lengthy and complex<br />
Act provides statutory recognition and protection for the<br />
concept of native title as recognised by the High Court in the<br />
case of Mabo v Queensland in 1992. Native title means<br />
rights held by indigenous inhabitants of Australia at and<br />
since the time of European settlement - it differs from<br />
conventional titles. The nature of native title rights vary<br />
from group to group according to laws and customs,<br />
however there must be a sufficient and relevant connection<br />
to the land in question, continuous since 1836 in South<br />
Australia. Native title may include the right to camp or<br />
travel across land, rights to hunt, fish, gather food and take<br />
materials (timber, bark, ochre etc.) from the land.<br />
Applications by Aboriginal claimants are recorded in the<br />
Register of Native Title Claims. The National Native Title<br />
Tribunal (NNTT) makes determinations on applications<br />
under the Act. A National Native Title Register comprising<br />
a record of all approved determinations made by the NNTT,<br />
Federal Court, High Court, other Courts or Tribunals and<br />
recognised State/Territory arbitral bodies.<br />
The Premier of South Australia declared in April 1994<br />
that SA would enact State legislation to ensure that State<br />
laws were consistent with the Commonwealth’s Racial<br />
Discrimination Act and as far as appropriate, the Native<br />
Title Act, while retaining the option to challenge the Native<br />
Title Act in whole or in part to make it more workable and<br />
less complex. Late in 1994, a package of four Native Title<br />
Bills was introduced into the SA House of Assembly and<br />
were all passed.<br />
In 1995 a ‘safety net’ clause was introduced into the<br />
Petroleum Act which gives a licensee first right to any<br />
licence which may be terminated due to no fault of the<br />
licensee.<br />
Licence holders are encouraged to develop a dialogue<br />
with regard to Aboriginal Heritage and related matters, with<br />
Aboriginal people having associations with their licence<br />
area.<br />
Following passage of the Commonwealth Native Title<br />
Amendment Act, the South Australian Government is<br />
considering establishment of a legislative response. A<br />
number of options are available under the new<br />
Commonwealth legislation to develop alternate State<br />
procedures to handle Native Title matters. A public<br />
announcement of the State’s response is likely later in 1998.<br />
Current Native Title Applications in the Cooper Basin<br />
region are shown on Figure 10.<br />
Environmental regulation<br />
Environmental issues pertinent to petroleum exploration<br />
are well managed in SA, primarily through proper<br />
operational planning in the initial stages. In order to ensure<br />
that activities are undertaken in a manner which avoids or<br />
minimises environmental impacts, several documents are<br />
required before approval to commence operations is given.<br />
First a Declaration of Environmental Factors (DEF) is<br />
required from the licensee. This is the licensee’s assessment<br />
of the environmental impact of the proposed activity. A<br />
Code of Environmental Practice is also required by<br />
regulation. The code describes procedures that the<br />
proponent will adopt during the planning, field management<br />
and monitoring phases of the operation.<br />
Santos Ltd. and their joint venture partners, who are the<br />
major oil and gas producers within the Eromanga and<br />
Cooper Basin, have developed Codes of Environmental<br />

Practice for exploration and production. The codes provide<br />
guidance to licensees on environmental issues that need to<br />
be taken into consideration in planning and undertaking<br />
exploration activities. These codes are currently being<br />
revised in a move towards an outcomes based approach.<br />
However in the interim they provide a standard acceptable to<br />
the Government. A company may either adopt these Codes<br />
or use its own Codes of Environmental Practice subject to<br />
approval by PIRSA.<br />
PIRSA is able to assist licensees by providing examples<br />
of the documentation and advising on their scope. To date<br />
there have been no significant concerns raised with regard to<br />
requirements to minimise the environmental impacts of their<br />
operations.<br />
The Codes are required to be reviewed regularly (at least<br />
every 3 years) to ensure techniques are up-to-date. All<br />
documentation is subject to regulation. A revision of the<br />
Petroleum Act is currently under way and any future<br />
documentation and operations will need to ensure the three<br />
prime objectives of exploration which are:<br />
1. undertake an appropriate planning and<br />
assessment process,<br />
2. avoid or minimise short to medium term<br />
impacts,<br />
3. avoid all long term impacts.<br />

APPENDIX 2 – DATA<br />
PEPS-SA ® (Attribute)<br />
PIRSA has developed PEPS-SA (Petroleum Exploration<br />
and Production System—South Australia), a comprehensive<br />
relational database containing a range of technical data<br />
relevant to the petroleum industry. PEPS-SA is being<br />
continually developed and is available for purchase. The<br />
key data element is the petroleum well, of which there are<br />
~1600 in SA. For each well there may be thousands of<br />
attributes. There are eight key modules comprising 99 data<br />
sets (see below).<br />
Data are supplied with a PEPS-SA menu-driven<br />
windows system. For clients without Paradox, a copy of<br />
Paradox Runtime and software to query and export the data<br />
are provided.<br />
PEPS-SA ® (Spatial)<br />
Bundled with the attribute data are Mapinfo spatial<br />
datasets. Viewing this data in a mapping package allows the<br />
geoscientist to turn on and off various layers of interest,<br />
zoom in and out etc, to allow the generation of a custom built<br />
base map which can be printed.<br />
There are more than 60 separate layers, ranging from<br />
general topographic data such as state boundaries, coastline,<br />
national parks and restricted areas, road, railways and<br />
various tenements, through to geologic layers such as basin<br />
outlines, well locations, seismic lines, seismic horizons,<br />
tectonic provinces, and many more.<br />
The PEPS-SA attribute and spatial data are bundled<br />
together as one package on CD-ROM which costs $3000.<br />
Update of PEPS-SA twice a year costs an additional $300<br />
per year.<br />

Core Photos<br />
The department has recently scanned all petroleum core<br />
photographs and the thumbnail images are present in the<br />
data package if you receive the CD-ROM version. Full size<br />
images are approximately 1500 pixels by 1000 pixels by 256<br />
colours. The total set contains over 1900 images and<br />
occupies 1.4 Gigabytes. These are available for purchase<br />
($250) on CD-ROM (3 disks) together with viewing<br />
software. The software links the photo to the attribute data.<br />

Seismic Mapping<br />
A program commenced in 1989 to consolidate open file<br />
basic and interpreted data into coherent data sets. The aim<br />
was to prepare regional interpretations of basin structure to<br />
attract explorers into prospective basins with vacant acreage.<br />
This program is nearing completion for the major onshore<br />
and large areas of the offshore basins.<br />
Cooper Basin Folio<br />
This folio is the culmination of an extensive seismic<br />
mapping and interpretation of the Cooper and Eromanga<br />
Basins in SA. Whilst this folio is restricted to the immediate<br />
area of PELs 5 and 6, regional datasets covering the<br />
Eromanga and Cooper Basins in SA, Queensland, NSW and<br />
the NT have been prepared as part of the National<br />
Geoscience Mapping Accord.<br />
• Volume 1 of the Cooper Basin Folio contains key<br />
seismic depth structure maps, formation isopachs<br />
and structural elements.<br />
• Volume 2 contains geological datasets including<br />
lithofacies maps and maturity maps of key source<br />
intervals (depths to oil and gas windows).<br />
All data are available in digital format and are<br />
supplemented by individual technical reports available from<br />
PIRSA. Each volume of the folio costs $1999, including<br />
postage and packing. In addition, individual hard copy maps<br />
can be purchased from $100 each, however discounts are<br />
available if map sets are purchased.<br />
Stack Seismic Data<br />
Archive processed data in SEG-y format are available for<br />
4474 seismic lines from the existing PEL 5 and 6 area. In<br />
most cases 3 versions of data are available:<br />
• Filtered Final<br />
• Filtered Migration<br />
• Raw Final for each line (where produced).<br />
PIRSA has a total of some 12300 data files on 12<br />
Exabyte Tapes. All data has had SP/CDP relationships<br />
embedded in the EBCIDIC header, and supporting attribute<br />
data relating to the line and data files. Approximately 10 %<br />
of all the data has been verified as correct and readable in the<br />
Geoquest IESX.<br />

APPENDIX 3 – LICENCE APPLICATION<br />
FORM AND PROCEDURES<br />
Review of Petroleum Act<br />
A Green paper on a review of the Petroleum Act 1940<br />
was released in 1997 and comments from industry and other<br />
interested parties received. Comments have been<br />
considered and Legislation is currently being drafted. It is<br />
anticipated that the draft Bill will be ready for Industry and<br />
other interest groups comments in October 1998.<br />
Key elements to changes in the Petroleum Act include<br />
implementation of objective regulation, with the willing<br />
assistance of industry; changes to the issue of tenements<br />
A draft Bill for a new South Australian Petroleum Act<br />
has very recently been made available for comment. This<br />
follows analysis of submissions following release of a<br />
Discussion Paper in 1996 and a Green paper last year. The<br />
legislation governing onshore petroleum exploration and<br />
production in south Australia had not undergone a major<br />
review since the Petroleum Act was proclaimed in 1940,<br />
although a number of amendments have been made from<br />
time to time. This legislation has served as an effective basis<br />
for regulation of the upstream petroleum industry. It has<br />
become evident, however, that the existing prescriptive<br />
regime is becoming less effective as advances are made in<br />
regulatory practice and community aspirations. The main<br />
thrust of the proposed legislation is to provide a modern,<br />
pro-competitive, efficient and flexible basis for<br />
administration of petroleum exploration and development.<br />
The objective is to establish a business environment that<br />
maximises investment opportunities for the exploration<br />
industry in the State and facilitates the development of<br />
discoveries. The main features of the Bill are:<br />
• establishment of a co-regulatory regime focussing<br />
on achievement of environmental, public safety and<br />
resource management objectives and reduced<br />
compliance costs (this is strongly supported by both<br />
industry and community interest groups);<br />
• licence allocation and management mechanisms to<br />
facilitate competition in line with competition policy<br />
principles;<br />
• rights of third party access to licensed pipelines<br />
(where not covered by the national access regime), to<br />
depleted reservoirs (for gas storage purposes); and to<br />
pipeline easements;<br />
• greater security of tenure for licences though<br />
improved registration procedures;<br />
• public consultation processes with regard to<br />
establishment of environmental objectives and for<br />
significant proposed activities (consistent with<br />
provisions of the Development Act);<br />
• reduced risk to Government for liabilities arising<br />
from the industry’s activities;<br />
• increased royalties from 2001 and a fee structure<br />
designed to encourage the adoption by industry of<br />
management systems to undertake their activities;<br />
and<br />
• the ‘grandfathering’ of existing Petroleum<br />
Exploration and Production Licence rights, with new<br />
exploration licences having rights to Retention<br />
60<br />
Licences but stricter criteria for Production<br />
Licences.<br />
The Occupational Health and Safety (OH&S) provision<br />
of the Petroleum Regulations have been repealed and<br />
substituted by regulation under the OH&S Act.<br />
Application<br />
Although there is no form set by regulation, an<br />
application for a Petroleum Exploration Licence (PEL) may<br />
be lodged in accordance with the attached pro forma, and<br />
should be accompanied by two copies of a plan of the<br />
application area and accompanied by the prescribed fee<br />
(which is currently A$ 2240 for each licence applied for).<br />
An application for a PEL can be lodged at any time over<br />
any area of the State not currently under a PEL or a<br />
Petroleum Production Licence (PPL) unless applications for<br />
the area have been specifically invited and a closing date<br />
nominated for receipt of applications.<br />
An application can be made by an individual(s) or a<br />
company(s) or a combination of an individual(s) or a<br />
company(s). When a foreign company makes an<br />
application, the foreign company must be registered as a<br />
foreign company under the provisions of the Australian<br />
Corporations Law. Information on registration<br />
requirements can be supplied on request.<br />
Technical Qualifications/Experience<br />
The applicant must submit with the application a<br />
summary of the technical qualifications of the applicant (or<br />
consultants/agents of the applicant) to satisfy requirements<br />
that the applicant is capable of satisfying compliance with<br />
the Petroleum Act and the terms and conditions of the<br />
licence.<br />
Financial Position<br />
Evidence of the financial position of the applicant is to be<br />
supplied to demonstrate ability to fulfil the proposed work<br />
program. Such evidence can be in the form of the latest<br />
annual report or a verifiable statement from an independent<br />
accountant/auditor/ financial institution. If financial<br />
resources are not available for the full five year program, the<br />
applicant will have to provide evidence that there are<br />
financial resources available for at least the first licence year<br />
program prior to the grant of the licence.<br />
Work Program<br />
The applicant must submit with the application a<br />
statement of exploratory operations the applicant proposes<br />
to carry out in each year of the five year term of the licence,<br />
including an estimate of exploration expenditure to be<br />
incurred in each year of the licence.<br />
A minimum exploratory expenditure for each of the first<br />
two years of the licence is $16 /km² per year, and $24 /km²<br />
for each of the remaining three years.<br />
Award Criteria<br />
The basic objective in awarding a Petroleum Exploration<br />
Licence is to select the work program most likely to achieve<br />
the fullest assessment of the petroleum potential within the<br />
licence over the initial five year licence term recognising the<br />
essential role of wells in the discovery of petroleum. Work
program bids will be assessed taking account of the criteria<br />
listed below.<br />
The criteria for assessment of work programs, not<br />
necessarily in order of priority are:<br />
• The number of wells to be drilled and their timing;<br />
• The amount and nature of seismic surveying to be<br />
carried out and its timing;<br />
• The number of years that an applicant is willing to<br />
guarantee the work program;<br />
• Other data acquisition and reprocessing to be carried<br />
out;<br />
• The extent to which the proposed work program<br />
reflects the information available from previous<br />
exploration;<br />
• The adequacy of financial resources and technical<br />
expertise available to the applicant.<br />
In addition to the above criteria, where work program<br />
bids are very similar, the benefits of the introduction of new<br />
explorers into the area may be taken into account.<br />
It should be noted that there are no criteria limiting the<br />
number of PELs which may be offered to one applicant<br />
(although in considering Competition Policy Principles it<br />
would require major work program benefits to offer more<br />
than three PELs to the one applicant in the first round of<br />
bidding). There will be no consideration taken of the<br />
success of applicants in the various bidding rounds in<br />
selecting successful applicants.<br />
Once a licence has been granted, a licensee is obliged to<br />
carry out the work program stipulated in the year the licence<br />
is in. Any failure to fulfil the work program for that year<br />
may, if a genuine ‘force majeure’ case is not proved, may<br />
result in cancellation of the licence. Variation of licence<br />
conditions are possible, however this would only generally<br />
be done where extraordinary cause exists, especially for a<br />
licence issued for which there were competing bids.<br />
Santos exploration drilling update<br />
Santos have amended their drilling program and a well<br />
may be drilled north of James 1 in Block CO98-C. Should<br />
this well, or any others proposed in Blocks CO98-A to K<br />
discover hydrocarbons before expiry of PELs 5&6, the PPL<br />
area will be excised from the relevant Block. However,<br />
basic data associated with wells will be available on expiry<br />
of PELs 5&6 on 1 March 1999.<br />
