The Scarborough gas resource is located in the Carnarvon Basin, approximately 375 km west-north-west of the Burrup Peninsula in Western Australia.
Estimated to contain 7.3 Tcf (2C) of dry gas, Woodside is proposing to develop the resource with 12 subsea, high-rate gas wells tied back to a semi-submersible platform moored in 900 m of water close to the Scarborough field.
Woodside’s preferred development concept is a proposed ~430km pipeline route transporting the gas to existing onshore Pluto LNG facilities, where additional LNG processing capacity will be installed. The composition of the Scarborough gas itself is well-suited to Pluto LNG, which is designed for lean gas and nitrogen removal.
The offshore pipeline would be operated by Woodside and would cross close to undeveloped fields in the Carnarvon Basin, creating future opportunities for third parties to tie-in fields too small to warrant stand-alone development.
Woodside is targeting a concept select decision in Q2 2018, front end engineering and design (FEED) entry in Q1 2019 and a final investment decision (FID) in 2020. A phased development drilling program is proposed, comprising seven wells, targeting upstream ready for start-up in 2023.
RFSU for the downstream is targeted in 2024 to meet the expected global LNG supply gap.
Subject to all relevant joint venture approvals being obtained, processing Scarborough through Pluto LNG will extend the life of the Woodside-operated world-class facility, and the supply of gas for domestic and export markets, for the next 30 to 40 years.
