Western Gas Corp. Pty Ltd. (WGC) has secured commitments to fully fund drilling of the Sasanof-1 wildcat in Carnarvon basin permit WA-519-P offshore Western Australia.
WGC will fund 25% of the cost. Farminees Global Oil and Gas Ltd. and Prominence Energy Ltd. will pay 50% and 25%, respectively.
Working interests are WGC 62.5%, Global Oil and Gas 25%, and Prominence 12.5%.
All major service and supply contracts for the drilling program have been awarded and the well is scheduled to spud in May using the Valaris MS-1 semisubmersible rig.
Sasanof-1 is west and southwest of WGC’s Equus gas fields, all of which lie between Woodside group’s Scarborough fields and Chevron group’s Gorgon-Io-Jansz fields.
The prospect covers an area of about 400 sq km and is updip of WGC’s Mentorc field in retention lease WA-70-R—part of Equus field group.
ERC Equipoise Ltd. estimated the prospect to contain a 2U prospective resource of 7.2 tcf of gas and 176 million bbl of condensate on a P50 basis. The high 3U prospective resource estimate is 17.8 tcf of gas and 449 million bbl of condensate on a P10 basis.
The prospect is a seismic amplitude-supported structural-stratigraphic trap in high quality sands at the top of the Cretaceous Lower Barrow group formation within the Exmouth Plateau.
