Challenge

  • Multiple ESP short runs primarily related to electrical failure 
  • Replacement equipment lead time estimated at six months 
  • No ESP surveillance

Solution

  • Redesigned the application to cover two wells with one GeoESP Box test container, which provides a plug-and-play solution for rapid deployment
  • Custom-designed eccentric centralizers protect cabling and MLE when running into the liner
  • Optimized down-hole performance with GeoController hardware
  • Connect to the Intelevate™ online monitoring platform

Result

  • Reduce the cost of replacement equipment 
  • Better placement of GeoESP in the liner to mitigate electrical failures
  • Immediate support to the thermal plant while MV VSD was replaced
  • Intelevate platform online monitoring and real-time performance visibility

Overview

A German geothermal operator with two wells operated by different electric submersible pumps (ESP) had multiple short runs due to electrical failures with the cable, motor lead extension (MLE), or the motor. With minimal customer support from the incumbent supplier, they turned to Summit ESP®, a Halliburton company, for a solution.

Challenge

When evaluating the customer's equipment, our engineer detected abnormalities in the medium voltage (MV) variable speed drive (VSD) output. The incumbent provider quoted at least six months' lead time to supply a replacement. It was further determined that poorly designed centralizers had not protected the cables or MLEs when the ESPs were set in the liner.

Solution

The team began redesigning the application with one GeoESP for both wells at half the cost for the customer. Custom-designed eccentric centralizers protected the ESP cabling from damage when running into the liner. A GeoESP® Box Test container provided a plug-and-play surface solution with direct adaptation for different grid voltages throughout Europe for immediate support to the thermal plant while the VSD was replaced. GeoController® hardware offered operators a quick, easy interface for field service and connected the plant to the Intelevate™ platform. This provided analysis of real-time test data from a mobile phone, and it set "smart" alarms for testing operations.

Result

The rapid deployment of the GeoBox allowed the customer options in case of surface equipment failure, keeping production online instead of an estimated six months of downtime at an estimated cost of at least €1.5MM in lost production/downtime and workover and equipment costs.
