A process for recovery oil includes recovering an oil/water mixture from an oil well. Thereafter, the method includes separating oil from the oil/water mixture to produce an oil product and produced water having dissolved silica therein. The produced water is directed to an evaporator and produces steam and a concentrated brine. The method or process entails mixing a precipitant or crystallizing reagent with the produced water or the concentrated brine and causing the silica to precipitate from the produced water or the concentrated brine. Steam produced by the evaporator is condensed to form a distillate which is directed to steam generator. At the steam generator the distillate is heated to produce steam which is injected into an injection well, giving rise to the formation of the oil/water mixture.

Procédé de récupération de pétrole comprenant un mélange de pétrole et d'eau d'un puits. Par la suite, la méthode comprend la séparation du pétrole du mélange de pétrole et d'eau afin de produire du pétrole et de l'eau contenant de la silice dissoute. L'eau produite est acheminée vers un évaporateur et produit de la vapeur et de la saumure concentrée. La méthode ou le procédé consiste à mélanger un agent réactif précipitant ou de cristallisation avec l'eau produite ou la saumure concentrée, ce qui provoque la précipitation de la silice de l'eau produite ou de la saumure concentrée. La vapeur produite par l'évaporateur est condensée pour former un distillat qui est acheminé vers le générateur de vapeur, où le distillat est chauffé pour produire de la vapeur, qui est injectée dans un puits d'injection, ce qui provoque la formation d'un mélange d'eau et de pétrole.
