Castex Energy

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.

Direct peers

• Talos Energy: Public Gulf of Mexico-focused upstream company with significant offshore operations and an active carbon capture and storage business line (Talos Low Carbon Solutions). Closest comparable peer given the overlapping Gulf of Mexico footprint, conventional E&P base, and parallel CCS strategy.
• W&T Offshore: Pure-play Gulf of Mexico operator with exploration and production assets across the shallow and deepwater Gulf. Directly comparable in basin focus, conventional asset profile, and similar mid-cap independent scale.
• LLOG Exploration: Privately held, Gulf of Mexico-focused exploration and production company. Highly comparable structure (private, GoM-focused) and similar operating approach to deepwater and shelf prospects.
• Murphy Oil: Independent E&P with meaningful Gulf of Mexico deepwater exposure alongside other international assets. Comparable in conventional upstream profile and offshore operating competency, though larger and more diversified.
• EnVen Energy: Privately held independent operator focused on the Gulf of Mexico shelf and deepwater. Directly comparable in basin, scale, and private E&P operator profile.
• Cox Operating: Private Gulf Coast-based exploration and production company with onshore and shallow-water Louisiana operations. Comparable in private status, regional focus, and conventional production profile.
• Kosmos Energy: Independent upstream operator with Gulf of Mexico assets among its portfolio, alongside offshore Africa. Comparable in conventional offshore exploration profile and similar independent scale.
• Magnolia Oil & Gas: Public E&P with material South Texas and Gulf Coast conventional production. Comparable in Gulf Coast basin exposure and conventional onshore operating model.
• Matador Resources: Independent E&P with Gulf Coast basin exposure and a growing emphasis on midstream and energy transition adjacencies. Comparable in Gulf Coast geography and conventional upstream focus.

Broad incumbents

• BPX Energy: U.S. onshore and offshore arm of BP, with significant Gulf of Mexico and Gulf Coast operations including CCS initiatives. Broad incumbent in the same geography whose conventional and emerging CCS activities overlap Castex's footprint.
