Rigless ESP replacement system
Retrieve and redeploy any standard electric submersible pump (ESP) system assembly without a rig using the plug-and-play design of the innovative ZEiTECS Shuttle rigless ESP replacement system. The system features two main assemblies: a retrievable ESP assembly and semipermanent completion components, including a docking station.
After the docking station is run to a shallow depth on jointed tubing, the retrievable ESP string with motor connector is assembled, lowered in the tubing, and landed in the docking station. The complete ZEiTECS Shuttle system is then lowered to pump setting depth.
The ESP string can be quickly unplugged from the docking station and retrieved in a few hours. A GS tool lowered on wireline, CT, or sucker rods is latched onto the ESP string, which is then retrieved through the tubing. After service or replacement, the ESP string is redeployed using the same method—eliminating the uncertainties, inconvenience, and economic impact of rig cost and availability.
E&P magazine honored the ZEiTECS Shuttle rigless ESP replacement system with a 2017 Special Meritorious Awards for Engineering Innovation, after judging by an independent team of experts. The system reduces operating costs and eliminates disruptions to operations by enabling any standard ESP assembly to be retrieved and redeployed without a rig—using wireline, coiled tubing, or sucker rods.Read article
