Electric wireline and tractor equipment were chosen to perform through-tubing electric submersible pump change-outs in a remote location with limited access and equipment availability. Electric wireline was available on location where other rigless options such as coiled tubing could not be mobilized. This paper records the retrieval of through-tubing-conveyed electric submersible pumps (TTC ESPs) from three wells and their replacement in two of these wells using a highly adaptable tool string. The application of an existing tool implemented in a novel manner provided benefits to the operator and has potential applications for other operators maintaining through-tubing-conveyed ESPs in deviated wells. The pump assemblies were removed through tubing while the permanently installed equipment, such as seal, motor and cable, remained in situ. All wells contained three individual assemblies to be retrieved including a tubing stop, tubing packoff with check valve and knock-out pressure relief valve, and the pump assembly. The assemblies were re-installed in two wells and the wells placed back in production. The method described herein confirms electric wireline and tractor equipment as a viable alternative for rigless replacement of through-tubing electric submersible pumps.
