Paper Number: SPE-70040-MS
... is that the resistivity logs indicate high water saturation, but water free hydrocarbon will be produced. This paper discusses the different reasons sandstone reservoirs can have low resistivity. The mechanisms resposibles for low resistivity phenomenon are described as being caused by the inclusion of clay or pyrite...

... core plug from depth 5308 ft. Brine based on the Lamunyon 50 water analysis and reservoir crude oil from the field were used in the test. The core was saturated with brine, then brought to irreducible water saturation by injecting oil. After aging in oil the core was placed in a brine-filled imbibition...
