Electrical submersible pump (ESPCP)
The PCP solution for highly deviated wells and offshore operations. The Electrical Submersible pump (ESPCP) is a ROD FREE SYSTEM that combines the advantages of ESP downhole motor with the benefits inherent to PCP technology.
Removing the rod string and driving the PCP with a downhole motor provides an alternative PCP system, to avoid the typical problems of parted rods and tubing failures in rod driven systems in high dogleg severity wells. This electrical submersible pump also outperforms ESPs, facing early failures (gas lock, sand wear, low efficiency).
PCM offers an energy-saving solution with an ESPCP system that uses a submersible Permanent Magnet Motor (PMM) and a PCM Slugger PCP with excellent reliability in all applications.
- Higher well performance and reliability including in multiphase conditions
- Improve PCP performance (remove flow area restriction from rod/centralizers)
- No gas lock
- Maintenance free
- Suitable for Offshore
An attractive artificial lift solution for production wells with high Dog Leg Severity, fields requiring power savings as well as for ESP conversion to offset declining wells.
- High performance downhole PMM with sensor-less drive control technology
- Constant torque over a wide range of speed 50-500 RPM
- Lower foot print
