Abstract

The focus of this study was on developing a Saturation-Height Model (SHM) based on mercury injection capillary pressure (MICP) analysis and core data of three wells drilled in a deep tight gas reservoir of the Amin formation, Oman, that can best fit to the water saturation calculated by logging data. The suggested SHM is a porosity dependent natural logarithmic function. The SHM indicated homogeneous transition zone with a deep fluid contact similar to all three wells.The calibration with logging data allowed for obtaining the GWC and more precise coefficients in the SHM equation for specific wells. The SHM closely simulated log-derived water saturation for entire Amin formation unaffected by rock type, which makes it useful for complex lithologies and un-cored intervals. The developed SHM can be used as a tool for water saturation evaluation independent from electrical rock properties obtained by logging.
