NW Shelf JV awarded greenhouse gas permit over depleted Angel field
Woodside Energy Ltd. has been awarded an additional greenhouse gas permit (G-10-AP) offshore Western Australia.
The permit covers 1,775 sq km and includes the depleted Angel gas field in northern Carnarvon basin. Field reservoir and geological data has been acquired through decades of production as part of the North West Shelf gas project, Woodside said.
The award ties in with the Woodside-operated North West Shelf joint venture’s plan to pursue potential offshore carbon capture storage (CCS) projects. The JV continues to assess the technical, regulatory, and commercial feasibility of capturing carbon emitted by multiple industries near Karratha in the Pilbara region of Western Australia, the company said.
The JV expects to pursue evaluation and appraisal work to determine the potential for the geological storage of CO2 in the new permit area.
The size of any potential CCS project is dependent upon results of evaluation work, but the aim is to process and store up to 5 million tonnes/year of CO2, the company said.
Permit participants, all with 20% interest, are Woodside, bp, Chevron, MiMi (Mitsubishi/Mitsui), and Shell (OGJ Online, Nov. 5, 2021).
The permit comes on the heels of storage assessment permits awarded in August to Woodside in Browse basin and Inpex in Bonaparte basin (OGJ Online, Aug. 24, 2022; Aug. 24, 2022).
