Abstract

The evaluation of shaly sand formation has a very close relationship with the study of electrical properties exhibits by the formation itself. The project done is based on the earliest resistivity model which proposed by Archie in 1942. Since this equation is only valid for clean sand, the model was modified by Patnode and Wyllie in 1950 to encounter the shale conductivity effect in shaly sand formation. However, this resistivity model contains limitation which is in high salinity of water, the shale conductivity will not able to significantly affect the total conductivity of the formation. In other words, when the water salinity is sufficiently high, the resistivity model of shaly sand formation will reduced closely to Archie‟s equation. Based on this hypothesis, the theory is brought into laboratory work where shaly sand core sample is tested for its resistivity in high salinity of water. Three types of core sample were being prepared by varying the shale content. The general properties of the samples were recorded as references. The result of core sample resistivity measurement will be able to describe concisely the accuracy of this model and generally draw its limitation or exception to be made for the model especially when the shaly sand formation encounters high water salinity.
