... concentration and slug size, oil viscosity, chemical adsorption, and its reversibility, among others. For high flow capacity thief zones and mobility ratios higher than 10, oil recoveries can be improved by increasing chemical concentration or slug size of treatments, or both. Low K v /K h (< 0.1) and high...

... injection location will alternatively change in each cycle of injection. Different design parameters are considered and studied including mobility ratio between water and oil phases, location of the water and the gas injectors, injection rate, WAG injection cycle. The results show that the proposed...

... miscible displacement. Experimental results determined the relationship of porous media characteristics such as dip angle and porous medium heterogeneities on the process at pore scale. The results were analysed using dimensionless Darcy Rayleigh number and mobility ratio to extend the results at larger...

... on demulsification. Mechanism by which chemical agent enhance oil recovery of heavy oil reservoir are: (1) significantly decreasing viscosity of heavy oil to improve mobility ratio volumetric and improve sweep efficiency; (2) decreasing oil-water interfacial tension to increase capillary number and improve oil...
