Sydney-listed BPH Energy has received the environmental review report for the Baleen gas exploration well in PEP11 off the coast of New South Wales, it said on April 16.  

Advent Energy is the operator of the permit through its wholly-owned subsidiary, Asset Energy, in a joint venture with Bounty Oil & Gas. BPH holds a passive interest in unlisted Advent.

Advent had engaged with Xodus Group in February to undertake a preliminary environmental screening assessment for the drilling of the Baleen well.  

The report was facilitated by the pre-existing environmental information from the prior technical work in the licence including the environmental plan which was accepted by the authorities for a 2D seismic survey which was commissioned by Advent and carried out in 2018. “The report has confirmed the programme required to undertake an environmental impact assessment to support the required approvals for the Baleen well,” BPH said. 

The report addresses the drill target on the Baleen prospect initially announced with a total depth of 2150 m on seismic data line B4-18. Advent now intends, subject to approvals and funding, to undertake deeper drilling to also undertake an evaluation of the offshore Sydney basin for carbon sequestration (carbon capture and storage). 

"This has resulted in a revised specification of a well to target early Permian sandstones for both hydrocarbon and carbon sequestration potential with a revised total depth being set at 3150 m," the company said.
