The group gravimetric capillary meter SKIF-GGK is designed to determine capillary properties and residual water saturation of core samples using a semi-permeable membrane under atmospheric conditions in accordance with OST 39-204-86.
The study results include the capillary pressure curves and the values of residual (irreducible) water saturation for each sample. Capillary properties are assessed across a range of excess gas pressures from 0.0007 to 1.38 MPa, encompassing the entire spectrum of sample permeability and water saturation of the pore space, from 100% to residual values.
