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.

Empirical relationships between the formatu=ion resistivity factor, the porosity, water saturation and the restivity of the fluid in the pore in clean, granular rock.

the area surrounding a well within which drawdown and production has changed the saturation and energy of the system.

a correction factor for the Darcy Equation to account for changes in pressure and fluid saturation along a fracture.

n: the number of centigrams of bromine that are absorbed by 1 gram of oil under certain conditions. This is a test for the degree of unsaturatedness of a given oil.

n: A kind of method measuring degree of unsaturation of bromine. It is a target of choosing oil of oil base drilling fluid.

the pressure necessary to achieve a given non-wetting fluid saturation of a rock.

n: a record that indicates the presence of hydrocarbons by measuring carbon atoms and that reveals the presence of water by measuring oxygen atoms. Oil and water saturations can be closely approximated without the requirement of adequate salinity of known concentration to calculate saturations (as in resistivity and pulsed neutron surveys).

n: laboratory analysis of a core sample to determine porosity, penneability, lithology, fluid content, angle of dip, geological age, and probable productivity of the formation.

n: Refers to the analysis of core in laboratory in order to confirm porosity, permeability, fluid saturation, dip, geologic period, lithology and production capacity of formation.

lab work on a core sample that may yield permeability, porosity, pore size distribution, grain size, density, etc.
