Buru Energy Ltd., Perth, found oil in its Currajong-1 wildcat in permit EP391 in the onshore Canning basin of Western Australia.
Wireline logs indicate porous zones with interpreted oil saturations at the top of the Ungani Dolomite equivalent section. Potential oil-bearing zones are also present in a lower dolomite section equivalent to the porous dolomite interval recorded in the nearby Praslin-1 well.
The log interpretation in these vugular dolomites needs to be validated by flow testing. The company has run 7-in. casing in preparation for a cased-hole test of the interpreted reservoir sections. Testing will take place once regulatory approvals have been obtained.
The well also detected a zone of up to 6% hydrogen in mudgas over an interval about 6 m from the measured depth of 2,014 m, validating the company’s view that the Canning basin could hold a future hydrogen resource.
The rig is being moved to the next well site. Rafael-1 is expected to spud in 2-3 weeks. The prospect is a geologically distinct formation to Currajong and has significantly larger potential resources.
Approvals for the third well in the program—Ungani-8 in production license L21—have been obtained. The well will be drilled at the conclusion of Rafael-1.
Buru is operator of all three wells with 50% interest. Origin Energy holds 50% in both the Currajong and Rafael wells. Roc has 50% interest in Ungani.
