Two potentially significant wildcats (SapuraOMV’s Kanga-1 and Western Gas Corp.’s Sasanof-1) are due to spud offshore Western Australia this month.

Kanga-1 will utilize Diamond Offshore’s Ocean Apex semisubmersible rig on location in permit WA-412-P in the Dampier subbasin.

Billed as a large oil prospect, Kanga lies 20 km west of Mutineer-Exeter and Fletcher-Finucane oil fields. The structure is also on trend and to the northeast of Woodside Group’s Goodwyn-Perseus-North Rankin gas and condensate fields.

The primary objective is the Jurassic-age Legendre formation. Independent consultant ERCE Australia Pty Ltd. estimated best case prospective resources of 170 million bbl.

Finder Energy farmed out the permit to SapauraOMV in December 2018 for a carry in the well which has been negotiated with a cap of US$940,000 for Finder’s contribution while retaining a 15% interest in the Kanga-1 well.

SapauraOMV is operator with 70%. Fugro Exploration Pty Ltd. holds the remaining 15% interest.

Further to the southwest, Western Gas expects to spud Sasanof-1 in permit WA-519-P on May 24. The Valaris MS-1 semisubmersible rig will begin its tow to location May 16.

The Sasanof gas prospect covers an area of about 400 sq km and is updip of Western Gas’ Mentorc field in retention lease WA-70-R which is part of the Equus field group.

ERC Equipoise Ltd. estimated Sasanof to contain a 2U prospective resource of 7.2 tcf of gas and 176 million bbl of condensate on a P50 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.

Western Gas will fund 25% of the well cost with farminees Global Oil and Gas Ltd. funding 50% and Prominence Energy Ltd. 25%.

Working interests in the well are WGC 62.5%, Global Oil and Gas 25%, and Prominence 12.5%.
