A Discrete-Domain Approach to Three-Phase Hysteresis in Porous Media
Helland, Johan Olav; Jettestuen, Espen; Friis, Helmer Andre` (Peer reviewed; Journal article, 2021)We present a discrete-domain approach to three-phase displacements and hysteresis in porous media. In this method, constrained energy minimization leads to evolution equations for local saturations that describe a wide ... -
A locally conservative multiphase level set method for capillary-controlled displacements in porous media
Jettestuen, Espen; Friis, Helmer Andre`; Helland, Johan Olav (Peer reviewed; Journal article, 2021)We present a multiphase level set method with local volume conservation for capillary-controlled displacement in porous structures. Standard numerical formulations of the level set method for capillary-controlled (or, ...
