stratigraphy and well correlation
Decreasing uncertainty in your model
It is essential to develop a good
understanding of the geometry,
continuity and depositional
settings of the sediment
packages in order to build
predictive geological and basin
models, and minimise the risk
of well target and performance
failure in exploration and
production projects.
GNS Science offers extensive
experience in combining wireline logs,
cuttings and core interpretation with
bio-, litho- and seismic stratigraphy
for building a geometric model and
reservoir/seal inventory, and providing
at a glance
Consistency It is essential that
seismic and existing well data
are made internally consistent
before work on a prospect or asset
evaluation can begin.
Input to basin modelling Paleo-water
depth maps are generated from well
and seismic data to highlight seabed
morphology and potential migration
path trends.

information about basin evolution in
terms of paleo-water depths and seabed
topography.
GNS Science is well-versed in seismic
and well sequence stratigraphy and has
carried out numerous multidisciplinary
stratigraphic projects in New Zealand
and overseas.
Both local and full-basin interpretations
can be carried out to place source
rocks, reservoirs and seals in a
sequence stratigraphic context and
determine burial history and basin
evolution. Digital outputs include litho-,
bio- and chronostratigraphic well tops
tied to the seismic data, log correlation
sections, and paleo-water depth maps.
Stratigraphy to seismic integration
New and existing well data are
reassessed and integrated to the
seismic dataset and horizons
interpretation in 2D and 3D.
Input to reservoir simulation We
have expertise in modelling in Petrel
software a variety of static scenarios
that provide a valid layering scheme
to be populated with reservoir
properties.
Save you time We overcome the
problem of multiple data vintages
and provide a standardised, qualitychecked
set of well data ready to be
loaded into your modelling software
package.
Input to CO 2 storage site assessment
We identify reservoir and seal pairs
and evaluate the storage potential
in deep saline aquifers and depleted
hydrocarbon reservoirs.

A review of litho-, biostratigraphy
and paleobathymetry based on well
data from central Taranaki Basin (Tui,
Maui and Maari petroleum fields) has
been carried out to reassess existing
stratigraphic framework and seismicto-well
ties. New stratigraphic dataset
and well correlation sections have been
created. The data are compatible with
seismic mapping in Geoframe/SeisWare,
static geo-modelling in Petrel and basin
modelling in PetroMod.
about us
about us
GNS Science has been conducting leading edge research in hydrocarbon exploration for over 30 years and more recently in CO2 storage. With a team of over 60 staff in the Natural Resources Group, we apply experience in satisfying client requirements to
provide a seamless link between scientific research and end-user needs in all aspects of exploration.

technical advice on how basin modelling
will bring new understanding to your
exploration area.
We developed a comprehensive well
summary sheet database for Taranaki
and New Zealand frontier basins,
identifying reservoirs and seals. The
database links multiple vintages of
drilling operations, acquisitions and
post-well study data and currently
includes 110 exploration and appraisal
wells.

An integrated workflow has been
applied to characterise clastic
reservoirs in the Kupe region, southern
Taranaki Basin. The methodology uses
simultaneous integration of geological
and geophysical data in 3D to define the
distribution of source rocks, reservoirs
and seals; extract facies from seismic
attributes; build a static geo-model
on a regional scale and construct
a 4D petroleum system model of
hydrocarbons generation and migration.
