Search Result for Gas Oil Ratio
opening ratio
The ratio between the pressure required to open the preventer and the well pressure under the rams.
GLR
Gas-liquid-ratio
compressability factor
The ratio of the actual volume of gas at a given temperature and pressure to the volume of gas when calculated by the ideal gas law.
gas-oil ratio
A measure of the volume of gas produced with oil, expressed in cubic feet per barrel of cubic meters per tonne.
relative density
2. the ratio of the mass of a given volume of a substance to the mass of a like volume of a standard substance, such as water or air.
gravity - specific
Density expressed as the ratio of the weight of a volume of substance to the weight of an equal volume of another standard substance. In the case of liquids and solids, the standard is water. In the case of natural gas or other gas materials, the standard is air.
relative permeability
The ratio of effective permeability to absolute permeability. The relative permeability of rock to a single fluid is 1.0 when only that fluid is present, and 0.0 when the presence of another fluid prevents all flow of the given fluid. Compare absolute permeability, effective permeability.
relative density
1. the ratio of the weight of a given volume of a substance at a given temperature to the weight of an equal volume of a standard substance at the same temperature. For example, if 1 cubic inch of water at 39 degrees F weighs 1 unit and 1 cubic inch of another solid or liquid at 39 degrees F weight 0.95 unit, then the relative density of the substance is 0.95. In determining the relative density of gases, the comparison is made with the standard of air or hydrogen.
