On June 22 the Alaska Department of Natural Resources' Division of Oil and Gas approved Oil Search (Alaska)'s application to form the Quokka unit in the central North Slope. OSA is a subsidiary of Santos Ltd.
OSA will be the operator of the new unit, which covers approximately 81,110 acres of state land and includes four leases on 1,480 acres committed to the Placer unit, which was terminated with the June 22 approval.
The rest of the Quokka leases, approximately 79,630 acres, are held 51% by OSA and 49% by Repsol, while Finnex has a 100% interest in the Placer acreage.
The new unit lies adjacent to the Southern Miluveach unit (Mustang), the Kuparuk River unit and the Pikka unit.
Based on non-confidential well control and other data, there are multiple reservoirs in the northern part of the new Quokka unit around the Mitquq and Placer wells, and multiple potential hydrocarbon accumulations across the rest of the proposed unit, the division said in its unit approval. (The southern end of the unit has not been drilled.)
The plan of exploration filed for the unit includes drilling two appraisal or exploration wells. One well will be drilled by second quarter 2026, and the other well by second quarter 2027.
Each of the wells will be drilled to a depth sufficient to fully test the entire Nanushuk section (5,500 feet true vertical depth subsea).
Earlier work detailed in the exploration plan lists several "non-drilling" activities, including interpretation of newly merged seismic data, addition of legacy seismic data into a new merged volume, refining static reservoir models and creation of a dynamic model for the Nanushuk 9 in the Mitquq area, a petrography study, and summer field studies to support drilling activities and ice roads.
