Electrical Properties Of The Lower Eocene Rocks In Qatar

Abstract

Thirteen limestone samples representing the Rus Formation (Lower Eocene) are selected' from four locations in Qatar Peninsula. These samples are subjected to electrical resistivity, porosity, shaliness factor and water saturation measurements. Very reliable formation resistivity factor—porosity relations have been obtained at two successive resistivity measuring cycles of rock samples saturated with two different brine concentrations. The limestones of the Rus Formation in each studied area are distinguished by a characteristic mean value of shaliness. A resistivity index—water saturation relation has been performed at the actual formation water resistivity.
