Our Technology

In 1995 we realized that ESP well interventions often result in high costs from both deferred production and lengthy intervention processes.

We set out to change that. To build the WRESP conveyance system, we developed technologies that can overcome traditional ESP limitations.

Each part of our technology is field tested and works for offshore, remote onshore, and high-production ESP wells. The cornerstone of our system is a permanent magnet motor, a compact, efficient alternative to conventional ESP induction motors.

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 are 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 (EPC) 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 adopted our testing protocols adopted 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 a significant 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 feet deep, 9 5/8” cased well (never produced), plus 30 surface acres and a 220’ X 160’ pad.
  • We performed internal tests and client field and client R&D tests at this location for major operators.

Future Applications

Using ESPs can significantly improve deepwater production and recovery. Operator concerns of system/pump/motor failure driving intervention costs and significant impact on production has limited the application of ESPs. With a reliable wireline intervention ESP system, riserless light well intervention becomes a valuable option on many subsea fields.

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