Texas Energy Mutual is an oil and gas company founded by energy industry veterans with over 150 years of collective experience. It focuses on exploration and production projects in Texas and Oklahoma, using its expertise to maximize results for shareholders. Exploration and production companies discover oil and gas reservoirs, drill wells, and produce and sell petroleum. They report daily, monthly, and quarterly production in barrels of oil, with a barrel equivalent to 42 gallons, and sometimes use the term barrel of oil equivalent to describe natural gas production. Reserves are the remaining quantities of oil and gas in the ground, which deplete over time through production, so companies also focus on exploration to locate new reserves and acquire existing producing properties.
