The Woodside Petroleum-operated North West Shelf JV received approval from the regulatory authority NOPSEMA for drilling its Greater Western Flank Stage 3 development offshore Carnarvon basin 128 km north northwest of Dampier in Western Australia.
Woodside’s Stage 3 program includes three production wells in the Greater Western Flank region in production license WA-5-L and one production well in the Lambert Deep development in WA-16-L.
Water depths are 125 m and 130 m, respectively.
The wells are targeting estimated recoverable reserves of 400 bcf of gas and will be tied back to Goodwyn A and Angel fixed platforms.
The Greater Western Flank project, initiated in 2015, is being developed to support production from the North West Shelf gas-condensate fields that have been flowing since 1984. The work involves gradually connecting an additional eight smaller fields surrounding the main North Rankin and Goodwyn fields.
The work—involving a moored semi-submersible drilling rig, a pipelay vessel, installation vessels and a variety of service craft—will begin in this year’s second quarter and be completed in 2023.
The NWS JV comprises BHP, BP, Chevron, Japan Australia LNG (Mitsui & Mitsubishi), Shell, and Woodside each with one sixth interest.
