PRODUCTION<br />

* During 2009 <strong>Woodside</strong>’s average share of gas production<br />

was approximately 39%. <strong>Woodside</strong>’s exact share of<br />

domestic gas production depends on the quantities and<br />

aggregate rate of production.<br />

This year <strong>Woodside</strong> celebrated its 25 year<br />

operatorship of the North West Shelf<br />

facilities, which have exported more than<br />

2800 LNG cargoes and currently supply<br />

around 65% of Western Australia’s pipeline<br />

gas.<br />

In 2009 there was strong performance<br />

from Trains 1, 2 and 3 and improved<br />

reliability from Trains 4 and 5, delivering<br />

approximately 57% of our foundation<br />

production.<br />

During the year, <strong>Woodside</strong> loaded 246<br />

cargoes of LNG, of which 31 were sold on<br />

the spot market. <strong>Woodside</strong>’s share of 2009<br />

LNG production was 2.40 million tonnes.<br />

Pipeline gas production was lower for the<br />

year due to decreased customer demand<br />

given re-established Varanus Island gas<br />

supply and a reduction of <strong>Woodside</strong>’s<br />

equity share in accordance with foundation<br />

agreements between the joint venture<br />

participants. Condensate production<br />

continued to be strong throughout the<br />

year as a result of the additional Stabiliser 6<br />

capacity and supply from the condensaterich<br />

Searipple and Angel reservoirs.<br />

LPG production also remained strong<br />

throughout the year. <strong>Woodside</strong>’s NWS oil<br />

production was lower in 2009 primarily due<br />

to natural field decline.<br />

Expansion continued with the North<br />

Rankin and NWS oil redevelopment<br />

projects currently underway. Progress<br />

was also made on the proposed Lady<br />

Nora oil development and the Greater<br />

Western Flank (GWF) gas and condensate<br />

development, which will assist in<br />

maintaining offshore supply and onshore<br />

capacity to around 2020.<br />

NWS contribution to <strong>Woodside</strong>'s total<br />

production (MMboe)<br />

NWS gas and condensate 57%<br />

NWS oil 6%<br />

<strong>Woodside</strong> other 37%<br />

During 2009, NWS contributed 50.9 MMboe to <strong>Woodside</strong>’s<br />

80.9 MMboe <strong>annual</strong> production.<br />

Train 5 and Stabiliser 6<br />

Modification of the main cryogenic heat<br />

exchangers on Train 5 was completed<br />

during planned maintenance in May,<br />

bringing the train to nameplate capacity.<br />

Train 5 is now contributing to increased<br />

LNG, condensate and LPG production.<br />

A sixth condensate stabilisation unit at the<br />

Karratha Gas Plant (KGP) was brought into<br />

production in May 2009 adding<br />

25,000 barrels per day of additional<br />

condensate processing capacity.<br />

Angel<br />

The Angel platform, which commenced<br />

production in Q4 2008 and supplies most<br />

of the additional gas needed for a five<br />

train operation, achieved unmanned status<br />

in mid 2009. The platform is remotely<br />

operated from the North Rankin A (NRA)<br />

platform, and gas and condensate from<br />

three wells are exported through a 50 km<br />

subsea pipeline to the NWS second<br />

trunkline.<br />
