The heat content of dry natural gas delivered in Texas, which uses the largest volume of natural gas in the United States, was among the lowest nationwide in 2023, averaging 1,018 British thermal units per cubic foot (Btu/cf), or 1.7% below the national average (1,036 Btu/cf), according to our Natural Gas Monthly.

The heat content of natural gas is an indicator of its composition and quality and can vary greatly depending on the geology of the producing basin. Wet natural gas is composed primarily of methane, which has a heat content value of 1,010 Btu/cf, as well as other hydrocarbon gases, mainly ethane and propane. Ethane has a heat content of 1,770 Btu/cf, and propane has a heat content of 2,516 Btu/cf. When there is more ethane and propane, the average heat
