Mexco Energy Corporation is an independent oil and gas company incorporated in 1972 (originally under the name Miller Oil Company) and now operating under its current name. Its headquarters are in Midland, Texas. Mexco’s business is concentrated on acquiring, exploring, developing, and producing hydrocarbon assets in the United States. It holds interests in working, royalty, and mineral rights across multiple U.S. states, but places particular operational emphasis on the Permian Basin in Texas and New Mexico.
A large share of Mexco’s operations is concentrated in two principal sub-regions of the Permian: the Delaware Basin (in Lea and Eddy Counties, New Mexico, and Reeves and Loving Counties, Texas) and the Midland Basin (in counties such as Midland, Reagan, Upton, and Martin in Texas). As of March 2022, these Permian holdings contribute the vast majority of its discounted future net cash flow from its proved reserves, reflecting the strategic importance of those basins to Mexco’s revenue base. In addition, Mexco holds smaller interests in producing wells across many other states (e.g. Texas, New Mexico, Oklahoma, Louisiana, Alabama, Mississippi, Arkansas, Wyoming, Kansas, Colorado, and more), though many of those non-Permian interests play a lesser role in its core operations.
In practice, Mexco participates in drilling, completion, reactivation, and development projects, often via non-operated interests where third-party operators execute the field work. The company has historically acquired producing properties (royalty, overriding royalty, mineral, and non-operated working interests) to bolster its asset base rather than focusing on high-risk exploration. As of its 2022 report, Mexco reported estimated proved reserves of about 1.616 million barrels of oil equivalent, balanced roughly between oil/natural gas liquids and natural gas. It utilizes horizontal drilling, hydraulic fracturing, and targeted infill or recompletion projects—especially in its Permian acreage—to enhance production from existing fields.
Mexco maintains a lean operational footprint, leveraging acquisitions and partnerships rather than building out large proprietary infrastructure. It also actively seeks to purchase royalty, mineral, and working interests from sellers, underwriting those acquisitions with internal technical evaluations and reserve assessments. Over time, Mexco’s strategy has been to reinforce its Permian base, optimize production in known fields, and incrementally grow through targeted acquisitions and participation in development drilling.
