Abstract

This research aimed to obtain the petrophysical parameters of the capillary pressure of a sandstonefrom 3D modelling of high-resolution rock images. By integrating a number of 2D slice results, a plot of capillarypressure vs water saturation was built. When performing digital simulations using 512 x 512 x 512 pixels, theeffect on the resulting image was clearly seen using interactive thresholding. The obtained porosity was 29.5%while the permeability was obtained through iteration as 3942 mD, a quite large value since it is a synthetic core.Meanwhile, at the depth of free water level of 984 ft, the capillary pressure is found to be 167.36 psi with watersaturation at 4%.
