About Oasis Petroleum Inc.

Oasis Petroleum Inc. (ticker: OAS) was a U.S.-based independent oil and gas exploration and production company listed on the NASDAQ in the United States. For investors, the key analytical point is that the company’s standalone corporate story has changed materially: following its 2022 merger with Whiting Petroleum, Oasis Petroleum Inc. was renamed Chord Energy Corporation. As a result, Oasis is best understood today as a legacy issuer whose historical filings, SEC disclosures, and insider-transaction records remain relevant, even though the original independent company no longer trades under the Oasis Petroleum name. The company was originally formed in 2007 and incorporated in Delaware in 2010. Its business model was centered on the acquisition, development, and production of onshore crude oil and natural gas assets in the United States, with a strong focus on unconventional resources. Over time, Oasis built a concentrated operating profile around the Williston Basin, one of the most important U.S. shale regions, and it also maintained related midstream and services capabilities at various points in its corporate history. Those ancillary activities included gathering, processing, marketing, and certain well-related services, designed to support the core upstream business and capture more value along the hydrocarbon chain. The company’s operational headquarters were in Houston, Texas, reflecting the center of gravity for U.S. energy management, capital allocation, and trading relationships. From a competitive standpoint, Oasis operated as a mid-sized independent E&P player in a sector defined by commodity-price exposure, reserve quality, drilling economics, and capital discipline. Its niche in the Williston Basin gave it scale and operating familiarity in a specific hydrocarbon corridor, but it also made earnings and cash flow highly sensitive to oil and natural-gas price cycles. For that reason, Oasis was typically analyzed as a focused upstream producer rather than a diversified energy conglomerate. Recent milestones are dominated by corporate transformation: the company’s restructuring history, the combination with Chord Energy, and the resulting end of Oasis as a separate listed entity. For French-speaking investors in France, Belgium, and Switzerland, OAS is therefore best viewed as a historical U.S. NASDAQ energy name tied to the United States market, with the most current investment relevance coming from its legacy SEC record and ownership/insider activity rather than from an ongoing independent operating platform.
