Patent number: 11713660Abstract: The present invention relates to methods for recovering hydrocarbons from subterranean formations. One such example embodiment injects a polymer solution into an upper layer of a subterranean formation and, likewise, injects an aqueous solution into a lower layer of the subterranean formation. Hydrocarbons displaced by at least one of the injected polymer and the injected aqueous solution are collected.Type: GrantFiled: February 14, 2019Date of Patent: August 1, 2023Assignee: TOTALENERGIES SEInventors: Arnaud Lager, Pierre-Edouard Schreiber

Publication number: 20180163523Abstract: 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.Type: ApplicationFiled: February 7, 2018Publication date: June 14, 2018Applicant: BP EXPLORATION OPERATING COMPANY LIMITEDInventors: Ian Ralph Collins, Arnaud Lager
