Oilfield

bimetallism

Oil & gas; Oilfield

The electromagnetic force created by two different metals in contact with each other. If two such metals are in contact in a logging tool, and also communicate along a conductive borehole, then a ...

skewness

Oil & gas; Oilfield

The degree to which a distribution has lost the bilateral symmetry of a normal distribution. Skewness is usually expressed qualitatively rather than quantitatively.

relative dielectric permittivity

The degree to which a medium resists the flow of electric charge divided by the degree to which free space resists such charge. The degree, or dielectric permittivity, is defined as the ratio of the ...

thermal maturity

Oil & gas; Oilfield

The degree of heating of a source rock in the process of transforming kerogen into hydrocarbon. Thermal maturity is commonly evaluated by measuring vitrinite reflectance or by pyrolysis.

collector

Oil & gas; Oilfield

The electrical device used on the axle of a spool or reel to provide electrical continuity between the rotating reel core and the stationary reel chassis. When using a coiled tubing string equipped ...

equivalent water resistivity

Oil & gas; Oilfield

The effective resistivity of the formation water or the mud filtrate, as it affects the electrochemical potential. The electrochemical potential is the main source of the spontaneous potential log. ...

polarization horn

Oil & gas; Oilfield

The effect on a propagation resistivity or induction log of charge buildup at the boundary between two formation layers with different dielectric properties. In a vertical well with horizontal ...
