The “PIK-GGC-6” group gravimetric capillarymeter

The group capillarymeter PIK-GGC-6 is designed to determine core samples capillary properties and residual water saturation using a semipermeable membrane at atmospheric conditions in accordance with OST 39-204-86. The method is considered classical and is based on displacement of the fluid saturating sample pore space under influence of excess gas pressure with periodic weighing of samples to assess their current saturation. The results of research are capillary pressure curves and values ​​of the residual (irreducible) water saturation of each sample. Sample electrical resistance (PIK-UES) is usually measured simultaneously with its weighing to determine saturation parameter and calculate the Dakhnov-Archie dependence. Capillary properties are determined in the excess gas pressure range from 0.0007 to 1.38 MPa in the entire range of sample permeability and water saturation of samples pore space from 100% to residual values.
