Abstract: The present invention is directed to a process for producing and separating oil. An aqueous fluid having an ionic content of at most 0.15 M and a total dissolved solids content of from 200 ppm to 10,000 ppm is introduced into an oil-bearing formation. Oil and water are produced from the formation subsequent to the introduction of the aqueous fluid into the formation. A demulsifier and a brine solution having a total dissolved solids content of greater than 10,000 ppm are mixed with the oil and water produced from the formation. Oil is then separated from the mixture of oil, water, demulsifier, and brine solution.

Abstract: The present invention is directed to a system for producing and separating oil. The system comprises an oil-bearing formation, a low salinity aqueous fluid having an ionic strength of less than 0.15M and having a total dissolved solids content of from 200 ppm to 10000 ppm, a brine solution having a total dissolved solids content of greater than 10000 ppm, and a demulsifier. The system further comprises a mechanism for introducing the low salinity aqueous fluid into and oil-bearing formation, a mechanism for producing oil and water from the formation subsequent to introducing the low salinity aqueous fluid into the formation, and a mechanism for contacting the brine solution and the demulsifier with the oil and water produced from the formation and for separating the produced oil from the produced water.

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.
Abstract translation: 本发明涉及从含油地层生产含有油和水的流体并从产生的流体中分离油相和水相的方法。 通过将聚合物混合在总溶解固体含量为200ppm至15,000ppm的水中形成水性聚合物混合物。 将含水聚合物混合物注入含油地层中，并且在将含水聚合物混合物注入到地层中之后，由含有油相和含水聚合物相的含油地层产生流体。 盐水与所生产的流体混合以增强油相与聚合物水相的分离。
