BTU – British Thermal Unit. The amount of energy
required to raise the temperature of one pound of water by one Fahrenheit
degree. One BTU is equivalent
to 252 calories, 0.293 watt-hours or 1,055 joules.
CCF – One Hundred Cubic Feet
One CCF is one hundred cubic feet of natural gas at standard distribution
pressure of 14.73 pounds per square inch and 60° Fahrenheit.
Christmas tree – The arrangement of pipes and
valves at the wellhead to control the flow of oil or natural gas and to prevent
blowouts.
CNG – Compressed Natural Gas
Completion – The procedure by which a
successful well is readied for production.
Compressor station – Stations located along natural gas pipelines
which recompress gas to ensure an even flow.
Conventional Resource – Any area where natural gas can be
drilled and extracted vertically.
Cubic foot – The amount of natural gas required at room temperature
at sea level to fill a volume of one cubic foot.
Derrick/Drilling Rig – A steel structure mounted over the
borehole to support the drill pipe and other equipment that is lowered and
raised during drilling operations (Sebuah
struktur baja dipasang di atas lubang untuk mendukung pipa bor dan peralatan
lainnya yang diturunkan dan dinaikkan selama operasi pengeboran).
Directional drilling – A technique that enables drilling
at an angle to reach a particular underground formation.
