Abstract
An experimental apparatus was designed and built to measure the in-situ steam and water saturations in The Geysers rock by using an X-ray CT technique. Water saturation was measured at a temperature of about 120oC but at different pressures. The pressure in the core sample ranged from 0 to about 50 psi. The experimental data from The Geysers rock were also compared to the theoretical results from a zero-dimensional model. X-ray beam-hardening effects are frequently reduced by the installation of core systems in water jackets or in sand packs. Such a method may not be convenient and may not work in some cases. A new approach was developed to measure fluid saturations by inclining the core to the scanning plane to reduce X-ray beam-hardening effects.
