42 Woodside Petroleum Ltd|Annual Report 2018
Woodside’s safe and reliable Pluto LNG facility is
positioned to unlock value from Scarborough.
Scarborough
Woodside assumed operatorship of Scarborough in April 2018,
following the acquisition of an additional 50% participating interest
in WA-1-R.
Woodside is well placed to deliver its preferred development
concept, processing Scarborough gas through a brownfield
expansion of Pluto LNG.
The Scarborough gas resource is located in the oshore
Carnarvon Basin, approximately 375 km west-north-west of the
Burrup Peninsula in Western Australia. This resource is estimated
to contain 7.3 Tcf (100%, 2C) of gas.
The 0.7 Tcf (1.4 Tcf, 100%, 2C) Thebe and 0.2 Tcf (0.5 Tcf, 100%, 2C)
Jupiter gas fields provide opportunities for future tie-backs to
Scarborough infrastructure.
The upstream development concept is to initially develop the
Scarborough gas field with up to seven subsea, high-rate gas
wells, tied back to a semi-submersible floating production unit.
The upstream design capacity will be 7.5 Mtpa (100% project,
including 1 Mtpa of domestic gas).
The proposed export pipeline route traverses the Carnarvon Basin,
in close proximity to undeveloped fields. Provision for future
tie-ins is planned and engagement is progressing with third-party
resource owners.
A geophysical and environmental deep-water survey of the pipeline
route was completed in July 2018, to define the environment
between the Scarborough and Pluto field areas.
Geophysical, geotechnical and metocean survey campaigns were
initiated in Q4 2018 and Q1 2019, to acquire data to support the
engineering design of the pipeline.
In December 2018, the Scarborough Joint Venture referred a
proposal for activities in State waters to the Western Australian
Environmental Protection Authority and the Commonwealth
Department of Environment and Energy.
Woodside awarded contracts in January 2019, in its corporate
capacity and funded on a 100% basis, for front-end engineering
design activities for the floating production unit, the export
trunkline and the subsea umbilical risers and flowlines.
Woodside is targeting FID in 2020 and upstream RFSU in 2023.
