About Us

Mustang Fuel Corporation is a privately held company headquartered in Oklahoma City, Oklahoma, along with its wholly owned subsidiaries Mustang Gas Products, LLC, and Mustang Fuel Marketing Company. Mustang’s operations include gas and oil exploration and production, natural gas gathering and processing, and natural gas marketing.



Established as Westoc Oil & Gas Company in 1949 by E.C. Joullian II, Mustang entered the pipeline business to supply natural gas to an electric generating station near Mustang, Oklahoma. During the next six decades, Mustang evolved as one of the Mid-continent’s leading independent oil and gas companies.

Mustang Fuel Corporation began its exploration and production efforts in 1971 with a successful well completion in LeFlore County, Oklahoma. Since then, Mustang has participated in thousands of wells across several states and is the current operator of over 250 properties. It also owns non-operated interest in more than 1,500 other properties and controls more than 100,000 net acres of undeveloped lease-hold through Kansas, Oklahoma, Texas and Utah.

In 2002, Mustang acquired gas gathering and processing assets covering producing areas in ten Oklahoma counties. These assets were combined with Mustang’s existing Spring Valley System in North Central Oklahoma to form Mustang Gas Products, LLC, a wholly-owned subsidiary of Mustang Fuel Corporation.

Mustang Fuel Marketing Company was formed in 1990 as a wholly owned marketing subsidiary of Mustang Fuel Corporation. Mustang Fuel Marketing Company has fast become one of the most recognized gas marketing companies in the Mid-continent by providing personal service and competitive pricing to many independent gas producers with a focus on the Oklahoma Intrastate pipelines.
