Abstract
A composition is described as including a mixture of citrus terpene hydrocarbons and an alcohol ethoxylate. The alcohol ethoxylate is represented by the formula R(C2H4O)nOH, where R is a branched or linear alkyl chain having from 12 to 15 carbons, and n is from 3 to 14. A method of removing pipe dope from a wellbore surface is also described. The method involves contacting the wellbore surface with the composition, and circulating the composition with respect to the wellbore surface. The pipe dope detaches from the wellbore surface and is dispersed in the composition, facilitating its removal.
