Triangle Energy Global Ltd. is set to begin drilling its first prospective Perth basin well in June or July having secured the Ventia 106 rig to drill the Booth-1 well in Permit L7 in Western Australia. This is the first prospect to be targeted using the 3D seismic acquired over the L7 and EP437 permits in 2022.
The Booth prospect, in the east of L7, will be the first well in the upcoming joint venture’s drilling campaign, targeting gas at the Kingia-High Cliff reservoirs with potential for oil or gas in the overlying Dongara and Jurassic sandstones, the company said in a release Apr. 17.
The Booth prospect has potential for both oil and gas, with a prospective resource range of 113-540 bcf of gas with a best estimate of 279 bcf (gross 100%, on-block).
The previously identified Becos oil prospect in EP 437 is intended to be the second well in the program, targeting the Bookara sandstone. Triangle expects to drill Becos in the September quarter 2024, subject to approvals. Becos has a prospective resource of 1-21 million bbl with a mid-case of 5 million bbl oil (gross 100%).
The first two wells are expected to be drilled using separate rigs. The Booth prospect, with a total depth of 2,900 m, requires a medium to large rig. The Becos prospect, with a prognosed depth of just over 1,000 m, is more suited to a smaller, more mobile rig, the company said.
Other gas prospects in the L7 permit are also potential targets for the third well.
Notable is Huntswell Deep, which is a previously unmapped structure that has been identified on the 3D seismic, also MH-2 Updip and Mountain Bridge South, in the southern portion of L7.
Triangle is operator of the L7 production license and the adjacent EP 437 exploration license with 50% interest.
L7 partners are New Zealand Oil & Gas Ltd. (25%), and Strike Energy Ltd. (25%).
