Abstract
A plunger sleeve for use in an artificial lift system for the production of hydrocarbons which includes an elongate body having an upper end, a lower end, and a central opening through the elongate body. The lower end includes a structural section forming at least a portion of the outer surface of the elongate body and a polymeric section forming at least a portion of an inner surface of the elongate body. At least a portion of the inner surface of the elongate body formed by the polymeric section within the lower end is configured to sealingly conform with a portion of an outer surface of a wellbore sealing device. An artificial lift system including the plunger sleeve and a method of proving artificial lift using the plunger sleeve is described.
