n: 1. the ability to transmit or convey (as heat or electricity). 2. an electricallogging measurement obtained from an induction survey, in which eddy currents produced by an alternating magnetic field induce in a receiver coil a voltage proportionate to the ability of the formation to conduct electricity. See induction log.

n: Measure of the quantity of electricity transferred across unit area per unit potential per unit time. It is the reciprocal of resistivity. Electrolytes may be added to a fluid to alter its conductivity.

the permeability of the pack times its width. Expressed in md-ft.

n: The target of capacity that the liquid pass through the screen mesh.

n: a substance that is an insulator, or nonconductor, of electricity.

a material that does not conduct electricity or has only a low electrical conductivity compared to a metal.

n: the sensing equipments which can measure the conductance of drilling fluid

n: a record of certain electrical charac-teristics (such as resistivity and conductivity) of forma-tions traversed by the borehole. It is made to identify the forma-tions, determine the nature and amount of fluids they contain, and estimate their depth. Also called an electric log or electric survey.

n: 1. a chemical that, when dissolved in water, dissociates into positive and negative ions, thus increasing its electrical conductivity. See dissociation. 2.the electrically conductive solution that must be present for a corrosion cell to exist.

n: A substance that dissociates into charged positive and negative ions when in solution or a fused state. This electrolyte will then conduct an electric current. Acids, bases, and salts are common electrolytes.


a material that, when dissolved in water, causes or increases the fluids’ electrical conductivity.
