Overview
Coterra was an American independent oil and gas exploration and production company headquartered in Houston, Texas. It developed from Cabot Oil & Gas Corporation, an exploration subsidiary of Cabot Corporation, and became a separately traded public company through an initial public offering in February 1990. The company subsequently expanded through acquisitions and divestitures, building positions in several major United States shale and conventional producing regions. Its principal operating areas included the Marcellus Shale in Appalachia, the Permian Basin of West Texas and New Mexico, and the Anadarko Basin. Its business was centered on finding, developing and producing hydrocarbons rather than selling consumer-facing energy products. Its production portfolio was weighted heavily toward natural gas, supplemented by crude oil and natural gas liquids. At December 31, 2024, the company reported estimated proved reserves of approximately 2.271 billion barrels of oil equivalent, with natural gas accounting for about 85 percent, petroleum 7 percent and natural gas liquids 8 percent. The company’s history included both portfolio expansion and asset rationalization. It acquired Washington Energy Resources in 1994 and Cody Energy in 2001, while later selling selected properties in Pennsylvania, Oklahoma, West Texas and the Eagle Ford Group. These transactions reflected the broader strategy of concentrating capital on areas where the company believed it could achieve competitive scale and attractive drilling economics. A major transformation occurred in October 2021, when Cabot Oil & Gas combined with Cimarex Energy and adopted the Coterra Energy name. The transaction created a more diversified United States producer with a substantial natural-gas base in Appalachia and oil-oriented assets in the Permian and Anadarko regions. In January 2025, Coterra announced or completed acquisitions of Franklin Mountain Energy and Avant Natural Resources for a combined consideration reported at approximately $3.9 billion, further increasing its exposure to the Permian Basin. Coterra also faced substantial environmental and legal controversy, especially concerning alleged water contamination in Dimock Township, Pennsylvania. The dispute involved methane and other substances detected in private wells in the Marcellus Shale region, became associated with the documentary Gasland, and generated years of regulatory and civil proceedings. In 2022, the company entered a no-contest resolution concerning well-water contamination and agreed to fund infrastructure and long-term water-bill commitments. A separate Pennsylvania case concerning contaminated wells in Lenox Township resulted in a reported fine in 2025. According to the referenced Wikipedia account, Coterra merged with Devon Energy in May 2026. Following that transaction, the Coterra name was retired. It therefore represents a former standalone exploration and production company whose identity was shaped by the consolidation of the United States shale industry, a gas-heavy reserve base, acquisitions in the Permian Basin, and significant environmental scrutiny.
History
Coterra originated as Cabot Oil & Gas Corporation, an oil and gas exploration subsidiary of Cabot Corporation. It became publicly traded through an initial public offering in February 1990, and by March 1991 it was entirely publicly owned. Its early development combined exploration activity with selective acquisitions and sales of producing assets. In 1994, the company acquired Washington Energy Resources in a stock transaction reported at $180 million. The acquisition later became controversial within the company, and chairman and chief executive John Lollar was removed in May 1995, partly because the transaction was viewed as poorly timed. In 1997, Cabot Oil & Gas sold oil reserves and land in northwestern Pennsylvania for approximately $92.5 million. In 2001, it acquired Cody Energy for approximately $230 million, expanding its resource and production portfolio. As unconventional drilling reshaped the American oil and gas industry, the company developed positions in several important basins. It operated in the Marcellus Shale, the Permian Basin and the Anadarko Basin, while periodically selling assets that did not fit its preferred portfolio. In 2013, it sold assets in the Marmaton play of Oklahoma and West Texas for approximately $160 million. In March 2018, it sold its Eagle Ford Group assets to KKR and Venado Oil & Gas for approximately $765 million. These transactions helped focus the business on selected core regions and reduced exposure to less central properties. The company’s best-known environmental dispute involved Dimock Township in Susquehanna County, Pennsylvania, an area above the Marcellus Shale. In 2009, methane was reported in 13 water wells, including one well that reportedly exploded. Investigations also identified substances including arsenic, barium, DEHP, glycol compounds, manganese, phenol and sodium at unacceptable levels in certain wells. Residents received alternative water supplies and compensation arrangements while mitigation systems were installed. The company disputed that hydraulic fracturing caused the contamination and argued that some methane was naturally pre-existing. In May 2012, the United States Environmental Protection Agency reported that methane and arsenic remained in only one well after treatment systems had been installed. The dispute later became associated with the 2010 documentary Gasland and continued through civil and regulatory proceedings. A decisive corporate milestone came in October 2021, when Cabot Oil & Gas combined with Cimarex Energy and changed its name to Coterra Energy. The combination joined a major Appalachian natural-gas business with oil-focused assets in the Permian and Anadarko regions. In January 2025, Coterra acquired Franklin Mountain Energy and Avant Natural Resources for a combined reported consideration of $3.9 billion, increasing its Permian presence. In 2020, Pennsylvania’s attorney general filed suit concerning the Dimock water controversy. In 2022, Coterra entered a no-contest resolution, agreed to provide $16.29 million for a new water-supply system through American Water Works, and accepted a 75-year obligation to pay water bills for affected residents. The related fracking moratorium was scheduled to end in October 2024. In 2025, the company was reportedly fined $299,000 over contamination affecting 13 wells in Lenox Township, Pennsylvania. The referenced Wikipedia account states that Coterra merged with Devon Energy in May 2026. The Coterra name was then retired, ending the company’s existence as a standalone branded oil and gas producer.

Products and positioning
Independent United States oil and gas exploration and production company focused on large-scale shale and unconventional resource positions, with a reserve base dominated by natural gas and supplemented by oil and natural gas liquids.
Hydrocarbon production
Natural gas
Natural gas was Coterra’s principal hydrocarbon output and the dominant component of its proved reserves. The company’s Appalachian Marcellus position gave it a large United States gas resource base, while its operations in other basins added geographic and geological diversity.
Hydrocarbon production
Crude oil
Crude oil was produced alongside natural gas from Coterra’s oil-oriented assets, particularly in the Permian and Anadarko basins. Oil production provided commodity diversification within a portfolio otherwise weighted toward natural gas.
Hydrocarbon production
Natural gas liquids
Natural gas liquids were recovered as associated hydrocarbons from the company’s production streams. They represented a smaller but commercially important portion of Coterra’s proved reserves and supported its broader liquids exposure.
