Simulating volume-controlled invasion of a non-wetting fluid in volumetric images using basic image processing tools

A new algorithm is presented for simulating volume-controlled invasion of a non-wetting phase into voxel images. This method complementary to the traditional morphological image opening which mimics pressure-based invasion. key advantage volume-based approach that fluid configuration at any saturation between 0 and 1 can obtained rather than irregularly widely spaced steps by methods. Because incremental increases in saturation, it becomes possible correctly predict defending trapping, not case when are applied. The verified comparing obtains near perfect agreement equal saturations as expected from theory. It also demonstrated capillary pressure curve be displays characteristic jumps pressure. Moreover, envelop peak pressures yields opening, so fact results proposed superset approach. Finally, compared multiphase lattice Boltzmann qualitatively similar were achieved substantially less time. more flexible terms variable contact angle inclusion viscous effects, but quasi-static injection fluid, viable alternative.
