Determination of Petrophysical Parameters Using Wireline Logs in Low Salinity Reservoirs

Abstract

Abstract This study defines an approach to determine porosity, fluid saturations and permeabilities from wireline log data in sandstone reservoirs containing low salinity formation brines. An extensive set of measurements were made on low invasion core were analyzed to establish the ground truth, and to control the input parameter choices for log analysis. A recently developed water saturation equation, that accounts for the different geometry of the condu…
