Exploration & Production
Origin holds significant producing assets; operates onshore processing facilities; and holds a portfolio of onshore and offshore exploration permits.
Reserves
Origin's current 2P (proved plus probable) reserves have been estimated at 5770 PJe . Approximately 90% of Origin Energy's 2P reserves are natural gas, of which about 8% are located in the South Australian and south west Queensland portions of the Cooper Basin. Another 56% of its natural gas reserves are source from the central Queensland coal seam gas fields. Coal seam gas now represents 71% of our 2P reserves.Exploration
Origin’s exploration strategy is to add gas reserves which can access existing infrastructure and local markets. Our exploration portfolio includes offshore and onshore acreage in the Otway and Perth basin, the offshore Bonaparte Bass Basins and the onshore Cooper/ Eromanga and Surat and Bowen Basin in Australia and in the Taranaki, Northland and Canterbury Basins of New Zealand.Projects
Origin Energy has a portfolio and major development projects which are developing oil and gas resources in Australia and New Zealand.The portfolio includes:
Kupe Gas Project (New Zealand)
This project proposes to extract gas from the Kupe gas field for processing through an onshore production station. The final development, budgeted at NZ $980 million, is expected to be operational by mid-2009.more...
Otway Gas Project (Victoria)
Origin Energy holds a 30.75% interest in the project to develop the Thylacine and Geographe gas fields located offshore from Victoria in southern Australia. more...Spring Gully expansion (Queensland)
Located 90km north of Roma in central Queensland, the original Spring Gully gas production facilities were built at a cost of $200 million and delivered on time and on budget in June 2005.A further $114 million was invested in the plant to double Spring Gully’s production capacity to around 85TJ/day. This gas plant was commissioned in August 2007 and maintains Origin's position as one of the major providers of commercially proven coal seam gas.
A further expansion of Spring Gully is underway:
- 60 new wells
- New compressors at the Strathblane Gas Plant
- A new gas plant in the southern part of the field
Producing assets
Origin Energy currently has its major production interests in the Cooper Basin, which has been the principal supplier of natural gas to New South Wales, South Australia and Queensland. The Cooper Basin producers entered into a long-term gas supply arrangement with AGL in December 2002 in which 505 PJ of gas will be supplied between 2003 and 2016.Other onshore production interests are located in the Surat and Bowen
Basins in Queensland (the latter including the Denison Trough), in the
Otway Basin (in the south east of South Australia and western Victoria)
and in the Perth and Carnarvon Basins in Western Australia.
Origin Energy is Australia's largest producer of coal seam gas (CSG).
We have interests in major CSG fields at Spring
Gully, Fairview and Peat
in the Bowen Basin in central Queensland. Origin operates all but one
(Fairview) of its CSG producing assets and has extensive CSG exploration
areas in the Bowen and Surat Basin,
the latter covering the Walloon Coals
which also have a large, as yet undeveloped, potential.
Origin is in a position to further commercialise the large CSG resource
represented by the Walloon coal measures of Queensland's Bowen and Surat
Basins as a source of natural gas supplying Queensland and the eastern
states of Australia. Offshore, Origin is the operator of the Bassgas
Project which was commissioned in 2006 to deliver gas, condensate and
LPG to the Victorian market.
