A simple apparatus for measuring the permeability of borehole core

Jermy, C. A. / Venter, B. J.

Abstract The measurement of permeability forms the basis for many engineering and geological engineering investigations. Most of these investigations require that a large number of determinations be made rapidly and accurately. The permeameter discussed here is a modification of the one designed by Ohle (1951). The permeameter allows for rapid sample change and is capable of measuring the permeability of a core sample using any fluid. The permeameter has been used successfully to test permeabilities as low as $ 10^{−5} $ millidarcies to permeabilities as high as 10 millidarcies at fluid pressures up to 10 MPa. The reproducibility of the tests was found to be in the order of 90%.
