Whiting Petroleum, an independent oil and gas company, completed the merger with Oasis Petroleum, an independent exploration and production company, in a $6bn deal. "The combination will bring together two excellent operators with complementary and high-quality assets to create a leader in the Williston Basin, poised for significant and resilient cash flow generation. Over the last year, both companies have executed a series of deliberate strategic transactions, reducing costs and establishing a leading framework for ESG and return of capital. The combination of the two companies, together with the ongoing momentum from these strategic actions, will accelerate our efforts and ideally position the combined company to generate strong free cash flow, execute a focused strategy and enhance the return of capital," Danny Brown, Oasis CEO.
