Instrument to measure the calorific value and/or the composition of the gas

Gas cap gas is a free natural gas which overlies and is in contact with crude oil in the reservoir. It is a subset of associated gas

A type of reservoir-drive mechanism in which the energy for the transport and production of reservoir fluids is provided by the expansion of gas either in the gas cap or inside the oil phase. In such a drive, the gas cap expands to force oil into the well and to the surface

The gas that accumulates in the upper portions of a reservoir where the pressure, temperature and fluid characteristics are conducive to free gas. The energy provided by the expansion of the gas cap provides the primary drive mechanism for oil recovery in such circumstances

Agreement that defines how any gas production imbalance in the system will be balanced out between the parties to the agreement

The Gas Safety Law sets specific directives regarding safety requirements. An unofficial translation of The Gas Law (Safety and Licensing), Sefer Hachukim, 5749-1989, p. 108, was last updated on January 7, 2008 and is available online at the MNI website

A non-solid, non-liquid combustible energy source that includes natural gas, coke-oven gas, blast-furnace gas, and refinery gas.
