ABSTRACT:
The permeability of a rock formation is determined at elevated pressures and temperature by heating a core sample taken from the rock formation and a fluid which is utilized to determine the permeability of the core sample to an elevated temperature. The fluid is injected under pressure and a second pressure which is higher than the injection pressure is applied to the surface area of the core sample. The effect of injecting a fluid such as a corrosion inhibitor or a polymer useful in secondary or tertiary recovery techniques on the permeability of the rock formation can be determined at elevated pressures and temperature by comparing the permeability of the rock formation before the fluid is injected and after the fluid is injected.
