A Case Study Of The Determination Of Connate Water Resistivi
A convenient and relatively accurate method for determining the connate water resistivity, Rw, values for wells in the Powder River Basin, Wyoming is described. This method is based on the change in the spontaneous potential (SP) response with different mud filtrate resistivities (Rm f) on repeat logging runs. The values of Rw obtained agree closely with those derived from conventional crossplot techniques of resistivity, Rt, and core porosity values.
