n: termination of a jurisdictional sale or service. Under Section 7(b) of the Natural Gas Act, the Federal Energy Regulatory Commission must determine in advance that the present or future public convenience and necessity" or depletion of gas supplies requires termination.

n: a hypothetical temperature at which there is a total absence of heal Since heat is a result of energy caused by molecular motion, there is no motion of molecules with respect to each other at absolute zero.

zero point on the absolute temperature scale;equal to -273.16 degrees C, or 0 degrees K (Kelvin),or -459.69 degrees F, or 0 degrees R (Rankine).

the ratio of the energy absorbed by a formation in relationship to the total energy passing through it.

n: a device that measures mechanical force. The energy measured is absorbed by frictional or electrical resistance.

n: a chemical additive that reduces the setting time of cement. See cement, cementing materials.

n: A downhole tool used in conjunction with a jar to store energy that is released suddenly when the jar operates.

an energy increasing device, with sudden energy release, used in a jarring string while fishing.

n: 1. a vessel or tank that receives and temporarily stores a liquid used in a continuous process in a gas plant. See drip accumulator. 2. on a drilling rig, the storage device for nitrogen-pressurised hydraulic fluid, which is used in operating the blow out preventers. See blowout preventer control unit.

n: Used to store nitrogen that provide the hydraulic oil energy for BOP operation.

near formation area is irradiated with neutrons that transform some nuclei into isotopes. The isotopes produced can be detected by radioactive energy levels and decay time. The original elements can be described from this behavior.

the range of wavelength energy that can be adsorbed by a given formation.
