Methods of inhibiting scale with alkyl diphenyloxide sulfonates

Abstract

A method of inhibiting the formation of scale, in particular barium sulfate and strontium sulfate scale, in an oil and gas well servicing fluid, the method involving adding a scale inhibitor composition that includes an alkyl diphenyloxide sulfonate into the oil and gas well servicing fluid. The alkyl diphenyloxide sulfonate is at one of a monoalkyl diphenyloxide monosulfonate, a monoalkyl diphenyloxide disulfonate, a dialkyl diphenyloxide monosulfonate, and a dialkyl diphenyloxide disulfonate.
