What North West Shelf Venture does
North West Shelf Gas Pty Ltd (NWSG) is a privately held marketing agency established in 1984 by the participants of the North West Shelf (NWS) Project to commercialize LNG and pipeline gas produced from the Carnarvon Basin offshore fields of Western Australia. The company is headquartered in Perth at Level 26, Mia Yellagonga Tower 3, and operates as the commercial interface for the Woodside-operated joint venture, whose participants (Woodside as operator, BP, Chevron, Japan Australia LNG/MIMI, Shell, and CNOOC) each hold a one-sixth share in the underlying infrastructure. NWSG's primary mandate is managing the contractual relationships with foundation Japanese utility customers (JERA, Tokyo Gas, Osaka Gas, Toho Gas, Shizuoka Gas) and historical Korean and Chinese buyers, alongside domestic pipeline gas supply into Western Australia.
The underlying technology platform centers on the Karratha Gas Plant, a multi-train LNG liquefaction and gas processing facility, paired with the North Rankin Complex offshore extraction assets. LNG production involves sequential removal of carbon dioxide, water, and heavy hydrocarbons, followed by staged cooling from -35°C to approximately -161°C, achieving a 600-fold volumetric reduction. The resulting LNG exceeds 85% methane content with heating values of 1067-1167 BTU per standard cubic foot. Pipeline gas, processed by removing water and impurities then separating heavy hydrocarbons, is compressed and metered into the Dampier to Bunbury Natural Gas Pipeline for distribution to Western Australian industrial, mining, power generation, and residential customers. Byproducts include condensate and LPG. The asset base represents over A$34 billion of cumulative investment, making it Australia's largest oil and gas resource development.
NWSG's revenue model operates on three streams: long-term contract LNG sales (primarily Asia Pacific under transaction-fee pricing not publicly disclosed), domestic pipeline gas sales to Western Australian customers, and an emerging third-party Gas Processing Agreement (GPA) tolling/service line that processes third-party gas at the Karratha facility as spare LNG train capacity emerges. The GPA business, formalized in 2020 with volumes of approximately 10.5 million tonnes of LNG and 24.7 petajoules of domestic gas contracted, marks the project's strategic pivot from upstream producer to midstream processor. Customer go-to-market is enterprise field sales with long-term, customized supply contracts; pricing is not publicly disclosed and is described as flexible and internationally competitive. The company has delivered over 5,700 LNG cargoes since the first cargo to Japan in 1989.

Products and services
- Liquefied Natural Gas (LNG) LNG produced at the Karratha Gas Plant through multi-stage liquefaction that removes carbon dioxide, water and heavy hydrocarbons and cools the gas from -35C to approximately -138C, then further to about -161C, condensing it to 1/600th of its original volume. Contains more than 85% methane with a heating value of 1067 to 1167 BTU per standard cubic foot. Sold primarily to Asia Pacific utilities.
- Pipeline Gas Domestic natural gas processed at the Karratha Gas Plant by removing water and impurities, separating heavy hydrocarbons, then compressing and metering before feeding into the Dampier to Bunbury Natural Gas Pipeline. Contains more than 85% methane with a heating value of 37 to 42.3 megajoules per cubic metre. Sold to Western Australian mining, industrial, power generation and residential customers.
- Condensate Condensate produced at the Karratha Gas Plant alongside LNG and pipeline gas as a byproduct of natural gas processing.
- Liquefied Petroleum Gas (LPG) LPG produced at the Karratha Gas Plant, extracted during the natural gas processing that produces LNG and pipeline gas.
- Gas Processing Agreements (GPAs) Third-party gas processing and tolling services offered at the Karratha Gas Plant as spare LNG train capacity emerges. GPAs enable third-party gas owners to monetize stranded offshore gas by leveraging NWS processing infrastructure under structured processing agreements.
