ABSTRACT:
The permeability of a core sample is measured during nonsteady state flow of fluid therethrough. A predetermined test pressure is supplied to an upstream end of the core sample while that sample is disposed in a fixed, closed volume and is subjected to a constant, predetermined confining pressure. The change in pressure across the core sample, with the passage of time, is measured; and the permeability of the core sample is determined as a function of the time-related measure of pressure change.
