We have interests in offshore production, LNG liquefaction and exploration licences in the North West Shelf (NWS) and Greater Gorgon areas of the Carnarvon Basin, as well as in the Browse Basin and Timor Sea. Woodside is the operator on behalf of the NWS joint venture, which produced more than 500 thousand boe/d of gas and condensates in 2018.
We have a 25% interest in the Gorgon LNG joint venture, which is operated by Chevron. The venture started operating in 2016, producing from the offshore Gorgon and Jansz-Io fields via a three-train LNG plant on Barrow Island.
We are the operator of a permit in the Browse Basin in which two separate gas fields were found: Prelude and Concerto (Shell interest 67.5% in each). Our development concept for these fields is based on our floating liquefied natural gas (FLNG) technology. The Prelude FLNG project, at its peak, is expected to produce about 130 thousand boe/d of gas and NGL, 3.6 mtpa of LNG, 1.3 mtpa of condensate and 0.4 mtpa of liquefied petroleum gas. During 2018, milestones included starting to commission the facilities and successful receipt of LNG and propane into the tanks. In December, wells were opened, entering the start-up phase. Our other interests in the basin include a joint arrangement, with Shell as the operator, for the Crux gas and condensate field (Shell interest 82%).
We are also a partner in the Browse joint arrangement (Shell interest 27%) covering the Brecknock, Calliance and Torosa gas fields, which is operated by Woodside. In November 2018, we agreed to sell our interest in the undeveloped Sunrise gas field in the Timor Sea (Shell interest 26.6%) to the government of Timor-Leste. We are a partner in both Shell-operated and other exploration joint arrangements in multiple basins, including Bonaparte, Browse, Exmouth Plateau, Greater Gorgon and Outer Canning.
We have a 50% interest in train one and a 97.5% interest in train two of the Shell-operated QCLNG venture. The two-train liquefaction plant has an installed capacity of 8.5 mtpa. We also operate the venture’s natural gas operations, which include wells, compression stations and processing plants in Queensland’s Surat Basin. We have interests ranging from 44% to 74% in 24 field compression stations and six central processing plants. Our production of natural gas from the onshore Surat Basin supplies the liquefaction plant and the domestic gas market.
A gas sales agreement between Arrow and QCLNG has been signed, under which gas from Arrow’s Surat Basin fields would flow to the QCLNG venture, that would then sell gas to local customers and export it through its gas plant on Curtis Island.
