Our Technology

To build the WRESP (Wireline Retrievable ESP) conveyance system, we developed technologies that can overcome traditional ESP limitations.​

Each part of our system is designed, manufactured and tested for demanding environments like the ones found in offshore, remote onshore and high-production ESP wells.

The cornerstone of our system is a permanent magnet motor. This serves as a compact, efficient alternative to conventional ESP induction motors.

Altogether, our ESP engineering resulted in a power delivery system and deployment technique that’s demonstrated performance for 20 years.

Operator-Driven R&D Initiatives

  • We’re developing deepwater, high-horsepower permanent magnet motors for larger casing and tubing sizes, with increased power densities of over 30 HP per foot.
  • We’re studying systems for use in subsea wells, where a riserless, light-water intervention vessel can be used without pulling the subsea tree.
  • The encapsulated power cable developed in collaboration with major operators has been the seed for a long-life permanent completions project, where cable and connector reliability limit ESP applications.

Motor Test System

  • Our system is an industry-leading, multi-million dollar motor test and qualification system designed for accelerated testing of PMMs and drives.
  • We developed a unique qualification process, consisting of eight test batteries, to qualify PMMs and the compatibility of drives with PMMs.
  • Major operators have adopted our testing protocols for their internal testing.
  • We’ve completed qualification tests for a number of operators for a range of PMMs and drives.

Test Well

  • In 2013, the company made the investment to develop a test site specifically tailored to the qualification of WRESP technology.
  • The site, an hour south of Houston, includes a 10,000-foot-deep cased well (never produced), plus 30 surface acres and a 35,200-square-foot pad.
  • We performed internal tests and client field and R&D tests at this location for multiple operators.

Applications of Our ESP Engineering

Using ESPs can significantly improve deepwater production and recovery. Operator concerns about system, pump or motor failure driving intervention costs and impacting production has limited the application of ESPs. With a reliable wireline intervention ESP system, riserless light well intervention becomes a viable option for many subsea fields.

Unconventional reservoirs produce significant debris and solids, in particular during the initial production period. The ability to replace ESPs with slickline has the potential to extend their application to many basins not considered candidates today.
