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 ...
relative dielectric permittivity
Oil & gas; Oilfield
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 ...
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 ...
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 ...
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 ...
