What Castex Energy does
Castex Energy, Inc. is a privately held, independent oil and gas exploration and production company founded in 1987 by John Stoika and headquartered in Houston, Texas. The company operates exclusively across the Louisiana and Texas Gulf Coast — including onshore, inland waters, and offshore Gulf of Mexico — acquiring, developing, exploring for, and monetizing conventional oil and gas assets and mineral interests. Its core technology is an extensive 3-D seismic portfolio that underpins a robust prospect inventory in its focus areas, and the company reports a track record of discovering over 3.1 Tcfe in resources and executing more than $1.3 billion in cumulative asset sales across commodity price cycles.
The company's revenue model is built on two primary streams: oil and gas production from owned and operated Gulf Coast assets, and the acquisition and monetization of conventional oil and gas properties and mineral interests. Customers are primarily institutional limited partners and joint venture partners who co-invest in Castex's asset acquisitions and development projects. Pricing is determined by commodity markets rather than disclosed contractual pricing. The company is led by a 13-person senior team with deep Gulf Coast expertise, including alumni of Exxon, BP, Apache, ENI Petroleum, and Freeport-McMoRan.
In 2021, Castex established Castex Carbon Solutions, a wholly owned subsidiary executing carbon capture and storage projects along the Gulf Coast with plans to capture and store over 3 million tons of CO2 annually. The company also maintains a Health, Safety & Environmental practice that includes operating one of the first mitigation banks in South Louisiana. Castex Carbon Solutions represents a strategic diversification into energy transition infrastructure, complementing the core conventional upstream business. The company remains privately held with no disclosed funding rounds, parent company, or public listing.
