Red McCombs began his energy ventures in the mid-1960s by investing in South Texas well production. Soon after, he started his own company to operate wells. Some of the major discoveries were the McCaskill Field in Karnes County and the Charline Field and Schreiner Ranch Field in Live Oak County.
Today, McCombs Energy has many long-standing relationships with exploration and production companies, and working interest production in Texas, New Mexico, Oklahoma, Alabama, and other states in the South and Southwest U.S.
In addition to the upstream activities in Texas, Red has oil and gas investments across the continental U.S., offshore, and in international plays as well.
