Quadrant Energy has decided to change its drilling plans in the Carnarvon Basin offshore Western Australia.
The firm had proposed to drill the Palmerston-1 well. After a technical evaluations and engagement with the regulator, Quadrant now plans to drill the Driftwood-1 well, says partner on the license, WA-320-P, Tap Oil (9.778% participating interest). The well is a commitment well, due in WA-320-P by Q4 2016.
The Driftwood-1 well has an expected total well cost of A$15.47 million (gross), which is substantially lower than the estimated cost for Palmerston-1 of A$98.2 million, says Tap Oil.
Driftwood-1 is in WA-320-P in the Barrow sub-basin of the Northern Carnarvon Basin, offshore Western Australia, approximately 1km north of the Rosily-1A exploration well which had minor oil shows.
Quadrant Energy is due to use the Noble Tom Prosser jackup drilling rig, with operations starting 1 August.
The well objective is to test the Early Cretaceous sandstones of the Mardie Greensand Member, Birdrong Member and Zeepaard Formation in a low-relief, northeast-southwest trending four-way dip closure.
