Questar's History

Questar Corporation's origins date to the 1922 discovery of natural gas in southwestern Wyoming by a predecessor exploration and production company.

The company completed construction of a pipeline in 1929 to transport natural gas to Utah markets. In 1935, various holdings were consolidated under the name Mountain Fuel Supply Company, which the parent company used until reorganizing in 1984 as Questar Corporation.

Today, Questar is a natural gas-focused energy company with five principal businesses: gas and oil exploration, midstream field services, gas and oil marketing and trading, interstate gas transportation and storage, and retail gas distribution.
