Accelerated swelling of oil-swellable elastomers in a well

摘要

A method of swelling an oil-swellable elastomer in a well comprising the step of: contacting the oil-swellable elastomer in the well with a treatment fluid, wherein the treatment fluid comprises: (A) an oil selected from the group consisting of alkanes and naphtha, wherein the oil comprises hydrocarbons having anywhere in the range of 5 to 21 carbons; (B) an α-olefin having anywhere in the range of 18 to 26 carbons; and (C) an activator for oil-swelling, the activator selected from the group consisting of: ketones, dodecane, terpenes, terpenoids, haloalkanes having from 9 to 20 carbons, and any combination thereof. An oil-swelled elastomer as produced by the method is also contemplated.
