Abstract: A process of recovering oil from an oil-bearing formation which process comprises injecting a surfactant containing enhanced oil recovery formulation into the formation via an injection well and recovering oil and optionally gas via a recovery well which process comprises determining the apparent viscosity of the enhanced oil recovery formulation at various ratios of enhanced oil recovery formulation to oil wherein the highest apparent viscosity is at most 4 times the lowest apparent viscosity measured.

Abstract: A process for recovering oil from an oil-bearing formation is provided. A first oil recovery fluid is introduced into a formation through a first well for a first time period and oil is produced from a second well. A second oil recovery fluid different from the first oil recovery fluid is introduced into the formation through the second well for a second time period after the first time period, and oil is produced from a third well, where the second well is located on a fluid flow path extending between the first and third wells.

Abstract: The present invention is directed to a process for producing a fluid containing oil and water from an oil-bearing formation and separating an oil phase and an aqueous phase from the produced fluid. An aqueous polymer mixture is formed by mixing polymer in water having a total dissolved solids content of from 200 ppm to 15,000 ppm. The aqueous polymer mixture is injected into an oil-bearing formation, and, after injecting the aqueous polymer mixture into the formation, a fluid is produced from the oil-bearing formation containing an oil phase and an aqueous polymer-containing phase. Brine is mixed with the produced fluid to enhance separation of the oil phase from the aqueous polymer phase.
