n: a measure of the ability of a single fluid (such as water, gas, or oil) to flow through a rock formation when the formation is totally filled (saturated) with that fluid. The permeability measure of a rock filled with a single fluid is different from the permeability measure of the same rock filled with two or more fluids. Compare effective permeability, relative permeability.

permeability to a single phase fluid in a cleaned core.

n: Schlumberger wireline tool that measures phase shift and attenuation of a 1100 MHz wave. Used for Hydrocarbon identification independent of formation water salinity, thin bed detection, Hydrocarbon saturation and mobility and to evaluate invaded zones.

n: 1. in general, a substance added in small amounts to a larger amount of another substance to change some characteristic of the latter. In the oil industry, additives are used in lubricating oil, fuel, drilling mud, and cement. 2. in cementing, a substance added to cement to change its characteristics to satisfy specific conditions in die well. A cement additive may work as an accelerator, retarder, dispersant, or other reactant.

n: The agent put into the drilling fluid in order to change some performances of the drilling fluid or slurry.

a compound incorporated into a gas, liquid, or solid system to alter the properties for a particular purpose.

n: the operation of bringing a measuring instrument, such as a meter, into a satisfactory state of performance and accuracy.

carbon and hydrogen compounds that may be branched of straight chained. Aliphatics may be paraffin (saturated) or olefinic (unsaturated).

n: a series of open-chained hydrocarbons. The two major classes are d1e series with saturated bonds and the series with unsaturated bonds.

a resin formed by reaction of polyhydric alcohols and polybasic salts. Saturated or unsaturated oils or fats are involved.

n: a leading national industry organisation established to disseminate scientific and technical ideas and data in the field of geology as it relates to oil and natural gas exploration and production. Its official publications are the AAPG Bulletin and the AAPG Explorer: Address: P.O. Box 979;Tulsa, OK 74101;(918) 584-2555.
