摘要
a method of treating aqueous wellbore fluids, comprising (a) converting one or more multivalent cations in a multivalent cation-containing aqueous fluid to form a mixture comprising one or more insoluble compounds and a treated aqueous fluid, (b) separating the treated aqueous fluid from the one or more insoluble compounds, and (c) contacting the treated aqueous fluid with a sulfide-containing aqueous fluid to form a compatibilized aqueous fluid, wherein the multivalent cation-containing aqueous fluid, the sulfide-containing aqueous fluid, or both were recovered from wellbores prior to (c).
