A UK-listed company has agreed to acquire an interest in a large offshore exploration gas prospect soon to spud offshore Western Australia while, in a separate venture, SapuraOMV has spudded the Kanga-1 offshore oil exploration well.

The Kanga prospect in Block WA-412-P is about 20 kilometres east of the producing Mutineer/Exeter and Fletcher/Finucane oilfields, and is targeting 170 million barrels of oil on a gross best case scenario, according to joint-venture partner Finder Energy.

The Diamond Offshore-owned semi-submersible Ocean Apex has spudded the well, said Finder.

The operator of the well is the Malaysian-Austrian company SapuraOMV.

Meanwhile, UK-listed Clontarf Energy has agreed to acquire a 10% interest from Western Gas in the large Sasanof-1 gas exploration well due to spud on 24 May 2022 using the semi-submersible Valaris MS-1.

Sasanof has a best estimate prospective resource of 7.2 trillion cubic feet of gas and 176 million barrels of condensate, with a 32% geological chance of success.

The well is located in the Greater Equus area which contains multiple undeveloped gas discoveries.

The investment by Clontarf reflected “international focus this year on the Sasanof prospect”, said Western Gas, the operator.

“Western Gas is delighted to welcome Clontarf Energy to the Sasanof campaign. The start line is in sight with only a matter of days before the rig departs for the Sasanof location on the North West Shelf,” said Will Barker, executive director.

The joint venture will comprise Western Gas (52.5%), Global Oil & Gas (25%), Prominence Energy (12.5%) and Clontarf (10%).
