The “PIK-UES” automated device for measuring core samples electrical resistance

The PIK-UES device is designed to measure electrical resistance of rock samples and reservoir water samples (or its models) at atmospheric conditions in accordance with GOST 25494-82. The measured values of samples electrical resistance are used to calculate resistivity, as well as porosity and saturation parameters, the Dakhnov-Archie indicators of a, m and n dependence. Measurements accuracy is achieved by using a pneumatic electrode close to the sample surface, providing stable clamping force.
