Water saturation estimation in tight shaly gas sandstones by application of Progressive Quasi-Static (PQS) algorithm - A case study

The saturation results from Indonesian model that is the best traditional log-derived saturation model in tight shaly sandstones were compared with this simulation results. It is concluded that there is a good match between log derived and simulation results. The simulation results show that it can be used as a tool for prediction of water saturation only with knowing the geometry of sedimentary environment in pore scale.
