What Enerplus does
Enerplus is an independent oil and gas exploration and production company that historically focused on developing high-quality assets in the Williston Basin, a major oil-producing region spanning parts of North Dakota and Montana. The company was founded in 1986, headquartered in Calgary, Canada, and traded on the NYSE under the ticker ERF. Enerplus's core technology centered on horizontal drilling and completion operations, supported by differentiated technical knowledge specific to the Williston Basin geology and reservoir characteristics. The company expanded its position through organic growth and acquisitions, including the $465 million acquisition of Bruin E&P HoldCo, LLC in January 2021.
In January 2026, Chord Energy completed its acquisition of Enerplus, creating a larger, more concentrated Williston Basin-focused operator. The combined entity is headquartered in Houston, Texas, and positions itself as a premier Williston Basin operator with a best-in-class balance sheet, disciplined capital allocation, and a diversified asset base. Revenue is generated through the sale of crude oil, natural gas, and natural gas liquids (NGLs) into global commodity markets via refineries, processors, and energy trading counterparties at market-based pricing. The combined company maintains an active capital return framework and serves global energy demand for abundant, affordable, and reliable hydrocarbon supply.
The business model is fundamentally commodity-driven: Enerplus produces oil and gas from its Williston Basin acreage and sells into commodity markets with no publicly disclosed long-term contracts or pricing tiers. Post-merger, the combined entity emphasizes capital discipline, operational excellence, and resilience to commodity price volatility as core operating principles. Following the merger, Enerplus ceased to exist as an independent publicly traded entity and now operates as a wholly-owned subsidiary of Chord Energy.
