Subsea artificial lift systems
Harness reliable ESP technologies for subsea, deepwater, and ultradeepwater systems.
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.
This rigless ESP replacement system minimizes deferred production, eliminates disruption to operations, and reduces HSE exposure and risk. Additional benefits include the following:
A step forward to reduce well intervention expenditure.
After 520 days in the well, the REDA ESP system was replaced rapidly with an integrated coiled tubing operation rather than a workover rig, Ecuador.
Integrated lifting solutions for enhanced well production.
