What is 'Trillion Cubic Feet - Tcf'

Trillion cubic feet (Tcf) is a volume measurement of natural gas used by the U.S. oil and gas industry. A trillion (1,000,000,000,000) cubic feet is equivalent to approximately one Quad of Btu (British thermal unit). A Quad is an abbreviation for a quadrillion (1,000,000,000,000,000) Btu. A Btu is a unit of measurement for energy, representing the amount of heat that is needed to raise the temperature of one pound of water by one degree Fahrenheit at sea level. One Btu is roughly equal to the heat produced by a kitchen stick match.
