Australian LNG player Woodside said that the estimated gross contingent resource dry gas volume for the Scarborough field has increased to 11.1 Tcf, 53 percent up from 7.3 Tcf.
Woodside’s interest in Greater Scarborough (covering the Scarborough, Thebe and Jupiter fields) comprises a 75 percent interest in WA-1-R (which contains the majority of the Scarborough field) and a 50 percent interest in each of WA-61-R, WA-62-R and WA-63-R, Woodside, the operator of these retention leases, said in its statement.
As a result of the Scarborough resource volume increase, Greater Scarborough contains an estimated gross dry gas contingent resource volume of 13.0 Tcf, a 41 percent increase from the previous 9.2 Tcf.
The increased volume estimates follow the completion of integrated subsurface studies incorporating full-waveform inversion (FWI) 3D seismic reprocessing and updated petrophysical interpretation.
The new FWI 3D seismic reprocessing improved the reservoir imaging quality and increased reservoir sand distribution. In addition, a comprehensive integrated review of the wireline log data and measurements from special core analysis has increased net sand proportion and gas saturations.
Woodside’s overall Corporate Contingent Resources (2C) have increased by 503 MMboe to 6,020 MMboe.
Woodside is targeting a final investment decision for the development of the Scarborough gas resource in the first half of 2020.
Scarborough gas would be initially processed on a deep-water floating production unit and transported through an approximately 430 km pipeline to a proposed second LNG production train at the existing Woodside-operated Pluto LNG facility on Western Australia’s Burrup Peninsula.
