Origin searches for new gas reserves which can be quickly developed and delivered to customers to help us meet the increasing demand for energy. We operate several offshore exploration permits in Australia, New Zealand and the Pacific and have a portfolio of onshore gas producing facilities that process the gas for our customers to use.

Exploring for new energy sources

Origin is constantly searching for new sources of energy in Australia and increasingly internationally, to help meet the growing energy demand of our customers. Exploration activity is carried out on land (called onshore exploration) as well as in the water (called offshore exploration). We target gas reserves located close to markets so that any new discoveries can quickly be developed.

Origin's exploration portfolio includes the Bowen, Surat and Cooper/Eromanga basins in Central Australia, the Otway and Bass basins in Southern Australia, as well as interests in the Perth Basin in Western Australia and the Bonaparte Basin in the Northern Territory. We also have exploration projects located in New Zealand in the Taranaki, Northland and Canterbury basins, as well as in Lao PDR, Thailand, Kenya and Vietnam.

Energy reserves

Origin is one of the largest holders of gas reserves in eastern Australia and a leading gas producer. Alongside our domestic gas operations, we are working with ConocoPhillips in a joint venture to deliver one of Australia's largest coal seam gas (CSG) to liquefied natural gas (LNG) export projects in Queensland.

Origin is Australia's largest producer of CSG. We have interests in major CSG fields at Spring Gully, Fairview and Peat in the Bowen Basin in central Queensland. Origin's current 2P (Proved plus Probable) reserves across its areas of interest total 6,158 petajoules equivalent (PJe). These reserves are primarily made up of CSG from the central Queensland fields, together with offshore fields with reserves of gas, condensate and LPG such as in the Bass Basin, Otway Basin and Taranaki Basin. We also have small reserves positioned in the Perth Basin and the onshore Taranaki Basin.

Gas producing operations

Origin operates several major gas producing facilities in Australia and New Zealand:

• BassGas Project (Victoria)
• Kupe Gas Project (New Zealand)
• Otway Gas Project (Victoria)
• Coal Seam Gas operations (Queensland)

Other onshore production facilities in which Origin has an interest are located in the Surat and Bowen Basins in Queensland (the latter including the Denison Trough), the Perth Basin in Western Australia and the Taranaki Basin in NZ.
