摘要： The invention relates to an apparatus for simultaneously injecting fluids into a plurality of samples of porous media, comprising: a plurality of holders for the samples of porous media, each holder comprising a sleeve and first and second platens, the first platen having an inlet for an injection fluid and the second platen having an outlet for a produced fluid, and the samples of porous media being arranged, in use, in each of the holders such that the first platen and second platen of each holder contact a first and second end of the sample of porous medium respectively, the inlet of each first platen being in fluid communication with an injection line for injecting fluid into the sample of porous medium arranged in the holder, the outlet of each second platen being in fluid communication with a dedicated effluent line for removing fluid produced from the sample of porous medium arranged in the holder, on-line and/or off-line analytical means for analyzing the fluids injected into each of the samples of porous media, on-line and/or off-line means for analyzing the fluids removed from each of the samples of porous media. A method of simultaneously injecting injection fluid into the samples of porous media is also provided.

摘要： A method for recovering crude oil from a reservoir that is penetrated by at least one injection well, the method comprising: injecting an aqueous displacement fluid comprising a solution of a zinc salt in an aqueous base fluid into the reservoir from the injection well wherein the aqueous base fluid has a total dissolved solids (TDS) concentration in the range of 200 to 250,000 ppmv (parts per million based on the volume of the aqueous base fluid), and a viscosity in the range of 1.00 to 2.00 centipoise (cP) at standard temperature and pressure; and wherein the aqueous displacement fluid has a dissolved zinc concentration in the range of 10 to 3,750 ppmv.

摘要： A method for recovering crude oil from a reservoir that is penetrated by at least one injection well includes injecting an aqueous displacement fluid into the reservoir from the injection well. The displacement fluid includes a solution of a zinc salt in an aqueous base fluid. The aqueous base fluid has a total dissolved solids (TDS) concentration in the range of 200 to 250,000 ppmv (parts per million based on the volume of the aqueous base fluid) and a viscosity in the range of 1.00 to 2.00 centipoise (cP) at standard temperature and pressure. The aqueous displacement fluid has a dissolved zinc concentration in the range of 10 to 3,750 ppmv. The aqueous displacement fluid includes dissolved chloride. The molar ratio of dissolved chloride to dissolved zinc in the aqueous displacement fluid is at least 5:1.
