The mixed-wet nature of reservoir formations imposes a wide range rock wettability from strong resident-fluid wetting to invading-fluid wetting. characteristics two-phase flow in porous media composed mixed-wetting surfaces remain poorly understood. In this study, we investigated the displacement resident ethylene glycol (EG) by hexane two micromodels identical 2.5-D geometry heterogeneity, wit...

Immiscible fluid displacement in porous media occurs several natural and industrial processes. For example, during petroleum extraction from rock reservoirs, water is used to displace oil. In this paper, we investigate the primary drainage imbibition a heterogeneous medium using an improved numerical model based on multicomponent pseudopotential lattice Boltzmann method. We apply recent develop...

the immiscible displacement of oil by water through a porous and permeable reservoir rock can be described by the use of a fractional flow curves (fw versus sw). water flooding project parameters can be obtained from the fractional flow curve. however, developing a representative fractional flow curve for a specific reservoir can be quite challenging when fluid and special core analysis data is...

Abstract. In this work, we study the finite element approximation of a model optimal control problem governed by the system describing the two-phase incompressible flow in porous media, with the aim to maximize production of oil from petroleum reservoirs. We first give the proof for the existence of the solutions of the control problem. The optimality conditions are then obtained and the existe...
