TERM DEFINITION
Gate Station
Generally a location at which gas changes ownership, from one party to
another, neither of which is the ultimate consumer. It should be noted, however,
that the gas may change from one system to another at this point without
changing ownership. Also referred to as city gate station, town border station,
or delivery point.
Gathering
The act of operating extensive low-pressure gas lines which aggregate the
production of several separate gas wells into one larger receipt point into an
interstate pipeline.
Gathering Agreement
Agreement between a producer and a gathering system operator specifying the
terms and conditions for entry of the producer's gas into the gathering system.
Gathering Line
A pipeline, usually of small diameter, used in gathering gas from the field to a
central point.
Gathering Station
A compressor station at which gas is gathered from wells by means of suction
because pressure is not sufficient to produce the desired rate of flow into a
transmission or distribution system.
Gathering System
The gathering pipelines plus any pumps, tanks, or additional equipment used to
move oil or gas from the wellhead to the main pipeline for delivery to a
processing facility or consumer.
Gauge Factor
A measure of the ratio of the relative change of resistance to the relative
change in length of a piezoresistive strain gage.
Gauge Pressure
Absolute pressure minus local atmospheric pressure.
Gauge, Pressure
Instrument for measuring the relative pressure of a fluid. Types include gauge,
absolute, and differential.
Gauging Tape
Measurements
This refers to a manual method of measuring the level of a liquid in a tank.
These measurements may be used to calibrate float levels.
GC
See Gas Chromatograph.
GC Module Assembly
The GC Module is comprised of 3 parts; Columns, Valves and Electronic
Interface. The Valves control flow of gas within the system. The Columns
perform the separation of the gas into component parts for analysis. The
Electronic Interface contains pressure and temperature sensors to monitor and
detect the different gas components as they leave the GC Columns.
