1. A method for preventing or mitigating the formation of, and/or removing, metal naphthenates in produced hydrocarbons during an artificial lift procedure, the method comprising:
injecting acid and sour gas simultaneously into produced hydrocarbons in a production well to facilitate lift of the produced hydrocarbons and to control the pH of fluids contained in the produced hydrocarbons to prevent an increase in the pH above a threshold pH value,
to thereby, as a result of said preventing an increase in the pH above the threshold pH value, prevent or mitigate the formation of, and/or remove, metal naphthenates in the produced hydrocarbons,
wherein the threshold pH value is the pH value at which metal naphthenates would otherwise form.
