EQT Corporation, formerly known as Equitable Resources, produces and sells natural gas. It earns 28% of its revenues through its natural gas and oil exploration and production business, 26% through its marketed natural gas segment, 23% through its residential gas deliveries, and the rest through various other businesses like natural gas transportation. The income it earns from its E&P business, however, is larger than the combined income of the rest of its segments.

Its petroleum business is the largest landholder in the Appalachian basin; while other producers in the region must spend millions on exploring for new reserves, EQT has drilled no exploratory wells in the past three years and still has a reserve life of 32 years. Decreasing world production and increasing world demand have driven oil prices through the roof and caused natural gas prices to fluctuate erratically, though the general trend has been upward. The company sells its petroleum on the open market because it can get higher profits.
