About TGTA Tulsa original in natural gas fueling.
Family owned and operated since 1991, TGT has helped make Tulsa a leader in compressed natural gas.
Our story
From a truck stop to ten countries.
TGT’s involvement in CNG began in 1989, when a major oil company asked Tom Sewell — then owner of Sewell Electric, a service-station construction and service contractor — to build a CNG station at the Midway Truck Stop between Tulsa and Oklahoma City.
Tulsa Gas Technologies was established on June 11, 1991, and the first TGT dispenser was built and sold the following month. Since then TGT has grown into the largest manufacturer of CNG dispensers in North America, with equipment across the U.S. and in more than ten countries.
TGT is owned and operated by Tom and Charles Sewell. Tom leads sales and operations; Charles leads service and research & development of new products.
