METHOD OF IMPROVING INJECTION PRESSURE AND ASPHALTENE REMEDIATION

Abstract: a method of removing deposits from a substrate includes contacting the deposits with a treatment fluid containing a solvent and an additive composition including at least one of an alkylbenzene sulfonic acid or an alkylbenzene sulfonate; and separating the deposits from the substrate with the treatment fluid to remove the deposits from the substrate, wherein the deposits includes asphaltenes. the deposits can be removed during a fracturing, acidizing, sand control, remedial, completion, or refracturing operation. the treatment fluid can also reduce the viscosity of crude oil and enhance oil recovery.
