ConocoPhillips said it intends to broaden oil exploration across Alaska’s Arctic North Slope, targeting prospects adjacent to its large Willow development. The company is betting the region holds significant undiscovered reserves that could bolster its long-term production profile. The program will require multiple federal and state permits and is expected to draw close scrutiny from environmental groups and regulators concerned about drilling in the fragile Arctic ecosystem. Even if approvals are granted, new barrels would not reach the market for several years, but the move underscores the producer’s confidence in continued global demand for crude.
