Productivity for Horizontal Wells in Low‐Permeability Reservoir with Oil/Water Two‐Phase Flow [PDF]
Mathematical Problems in Engineering, 2014 This paper presents a semianalytical steady‐state productivity of oil/water two‐phase flow in low‐permeability reservoirs with both top and bottom boundaries closed which takes the permeability stress‐sensitive and threshold pressure gradient into account. Using the similar approach as Joshi’s (1988), the three‐dimensional (3D) horizontal well problem

Modeling of Two-Phase Flow in Rough-Walled Fracture Using Level Set Method
Geofluids, 2017 To describe accurately the flow characteristic of fracture scale displacements of immiscible fluids, an incompressible two-phase (crude oil and water) flow model incorporating interfacial forces and nonzero contact angles is developed.

Advanced Functional Materials, EarlyView.A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...
