Current through Reg. 49, No. 28; July 12, 2024
The following words and terms, when used in this chapter,
				  shall have the following meanings, unless the context clearly indicates
				  otherwise.
(1) Adjacent estuarine
				zones--This term embraces the area inland from the coast line of Texas and is
				comprised of the bays, inlets, and estuaries along the gulf coast.
(2) By-product--Any element found in a
				geothermal formation which when brought to the surface is not used in
				geothermal heat or pressure inducing energy generation.
(3) Casinghead gas--Any gas or vapor, or
				both, indigenous to an oil stratum and produced from such stratum with
				oil.
(4) Commission--The Railroad
				Commission of Texas.
(5) Common
				reservoir--Any oil, gas, or geothermal resources field or part thereof which
				comprises and includes any area which is underlaid, or which from geological or
				other scientific data or experiments or from drilling operations or other
				evidence appears to be underlaid by a common pool or accumulation of oil, gas,
				or geothermal resources.
(6) Cubic
				foot of gas or standard cubic foot of gas--The volume of gas contained in one
				cubic foot of space at a standard pressure base and at a standard temperature
				base. The standard pressure base shall be 14.65 pounds per square inch
				absolute, and the standard temperature base shall be 60 degrees Fahrenheit.
				Whenever the conditions of pressure and temperature differ from the standard in
				this definition, conversion of the volume from these conditions to the standard
				conditions shall be made in accordance with the ideal gas laws, corrected for
				deviation.
(7) District office--The
				commission-designated office for the geographic area in which the property or
				act subject to regulation is located or arises.
(8) Dry gas--Any natural gas produced from a
				stratum that does not produce crude petroleum oil.
(9) Exploratory well--Any well drilled for
				the purpose of securing geological or geophysical information to be used in the
				exploration or development of oil, gas, geothermal, or other mineral resources,
				except coal and uranium, and includes what is commonly referred to in the
				industry as "slim hole tests," "core hole tests," or "seismic holes." For
				regulations governing coal exploratory wells, see Chapter 12 of this title
				(relating to Coal Mining Regulations), and for regulations governing uranium
				exploratory wells, see Chapter 11, Subchapter C of this title (relating to
				Surface Mining and Reclamation Division, Substantive Rules--Uranium
				Mining).
(10) Gas lift--Gas lift by
				the use of gas not in solution with oil produced.
(11) Gas well--Any well:
(A) which produces natural gas not associated
				or blended with crude petroleum oil at the time of production;
(B) which produces more than 100,000 cubic
				feet of natural gas to each barrel of crude petroleum oil from the same
				producing horizon; or
(C) which
				produces natural gas from a formation or producing horizon productive of gas
				only encountered in a wellbore through which crude petroleum oil also is
				produced through the inside of another string of casing or tubing. A well which
				produces hydrocarbon liquids, a part of which is formed by a condensation from
				a gas phase and a part of which is crude petroleum oil, shall be classified as
				a gas well unless there is produced one barrel or more of crude petroleum oil
				per 100,000 cubic feet of natural gas; and that the term "crude petroleum oil"
				shall not be construed to mean any liquid hydrocarbon mixture or portion
				thereof which is not in the liquid phase in the reservoir, removed from the
				reservoir in such liquid phase, and obtained at the surface as such.
