Pore-scale investigation of selective plugging mechanism in immiscible two-phase flow using phase-field method

Abstract: Biotechnology has had a major effect on improving crude oil displacement to increase petroleum production. The role of biopolymers and bio cells for selective plugging of production zones through biofilm formation has been defined. The ability of microorganisms to improve the volumetric sweep efficiency and increase oil recovery by plugging off high-permeability layers and diverting injection fluid to lower-permeability was studied through experimental tests followed by multiple simulations. The main goal of t… Show more

“…Fluid–fluid interactions define static as well as dynamic interfacial properties at the oil–brine–system interface, considering the possible chemical interactions taking place [ 3 , 4 , 5 , 6 , 7 , 8 ]. Moreover, rock–fluid interactions could result not only in wettability alterations [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ], but also in fine migration, often leading to permeability changes [ 15 , 16 ], and other possible mechanisms related to the transport in porous media. The main contributions of both F–F and R–F on additional oil recovery remain subject to study, especially when hybrid processes are applied/evaluated.…”

“…Phase-field models for twophase flows have been extensively studied in the literature, for instance [18][19][20][21][22]. Thermodynamically consistent phasefield-based diffuse interface models and simulation of twophase flows in porous media have been reported in the literature, for instance [23][24][25][26][27][28][29][30], which introduce free energy potentials to characterize capillarity effect caused by the surface tension. The key ingredient of phase-field models of binary fluids is that a free energy potential is introduced to characterize phase behaviors, especially capillarity effect caused by the surface tension.…”
