Abstract
A core sample of a porous media of identified porosity at atmospheric conditions is saturated with a fluid having an identified X-ray attenuation coefficient. The fluid saturated sample is scanned with X-rays. Confining stress is applied to the sample and the sample is again scanned with X-rays. Porosity of the sample at confining stress is then determined from the porosity at zero confining stress, the X-ray attenuation coefficient of the saturating fluid, and X-ray attenuation coefficients determined from the scanning of the sample at both atmospheric conditions and at confining stress. Pore volume compressibility is determined from the changes in porosity and X-ray attenuation coefficients from atmospheric to confining stress conditions.
