- APA Corporation and its partners Lagniappe Alaska and Oil Search announced a significant oil discovery at the Sockeye-2 exploratory well in Alaska's North Slope. - The Sockeye-2 well reached a depth of about 10,500 feet and found approximately 25 feet of net oil pay in a high-quality reservoir. - The reservoir is characterized by an average porosity of 20% and shows better-than-expected porosity and permeability compared to similar regional fields. - Additional zones of potential pay were identified in the shallower Staines Tongue formation. - The Sockeye prospect spans 25,000 to 30,000 acres and confirms the partners' geological and geophysical models, reducing risk for other prospects in the area. - Wireline logging has been completed and further data collection, including core acquisition and planned flow testing, is underway. - This exploratory well is the second successful drilling in a larger position on state lands held by the partnership. - Bill Armstrong, CEO of Armstrong Oil & Gas, highlighted the potential of the North Slope with existing infrastructure to support these discoveries. - John J. Christmann, CEO of APA Corporation, expressed encouragement by Sockeye-2 results and looks forward to the flow test results. - APA Corporation is involved in exploring and producing oil and natural gas across various regions including the United States, Egypt, and the United Kingdom.

APA Corporation and Partners Lagniappe Alaska and Oil Search Announce Significant Oil Discovery in Alaska’s North Slope at Sockeye-2 Exploration Well; Partners Proceeding with Further Evaluation and Testing:

HOUSTON, March 17, 2025 (GLOBE NEWSWIRE) -- APA Corporation (NYSE, Nasdaq: APA) and its partners Lagniappe Alaska, LLC, an Armstong company, and Oil Search (Alaska), LLC, a subsidiary of Santos Limited, today announced preliminary results of the Sockeye-2 exploratory well. Apache holds a 50% working interest, operator Lagniappe and partner Santos each hold 25%.

The Sockeye-2 well was drilled to a depth of approximately 10,500 feet and successfully encountered a high-quality reservoir with approximately 25 feet of net oil pay in one blocky, Paleocene-aged sand with an average porosity of 20%. As compared to recent regional field analogues in the Brookian play, the porosity and permeability are both better than expected, with the permeability to be confirmed through a planned flow test. Additional zones of potential pay were also encountered in the shallower Staines Tongue formation.

The Sockeye prospect is amplitude supported across 25,000 to 30,000 acres, and confirms the partners’ geologic and geophysical models, derisking numerous additional prospects in the area. Wireline logging is complete and additional data collection is underway, including acquiring core and flow testing the well. The partners will provide further updates following the flow test results.

“The Sockeye-2 test is the second successful exploratory well drilled by the partnership on a 325,411-acre position on state lands. The first well, King Street-1, was a new field discovery with oil in two separate Brookian Zones. The Sockeye-2 well further demonstrates the potential of the play, presenting an exciting opportunity in an active area of the North Slope with significant existing infrastructure,” said Bill Armstrong, CEO of Armstrong Oil & Gas.

“We are very encouraged by the results at the Sockeye-2 well, which further proves our geologic and geophysical models and confirms a working hydrocarbon system. We look forward to the results of the flow test and sharing more information about the broader opportunity in Alaska,” added John J. Christmann, APA Corporation CEO.
