ABSTRACT:
Multi-phase fluid saturation in a sample of a porous media is determined through computed tomographic scanning. The sample is scanned with X-rays of differing energies in both the fluid saturated and fluid-extracted states. Each of the extracted fluids is also scanned at differing X-ray energies. The computed tomographic images produced are utilized in the determination of the X-ray mass attenuation coefficients for the sample and the extracted fluids. From these mass attenuation coefficients, the weight fractions and volume fractions of each of the extracted fluids are determined.
