Developed over a 20-year period, with 21 permanent completions and 35 slickline runs/retrievals, the AccessESP system leads the industry. By collaborating with operators throughout its development, it meets their needs for well design and intervention barrier policies.

Two field proven technologies form the heart of the system; a permanent magnet motor and a side pocket wet connect system. This patented system works in 4.5” tubing, the majority of high value wells. It allows slickline retrieval without killing the well and full bore access when pulled.

Conventional Installation (with Rig)   AccessESP (Rigless)
Wait time for rigs, if you can obtain one   Low-cost standard slickline, coil tubing, or downhole tractor conveyance, readily available
ESP replacement in months   Retrievable assembly replacement in hours
Significant lost production   Minimal lost production
Kill the well prior to replacement   Lubricator provides live well intervention
High intervention costs   Low intervention costs
Large operational footprint   Small operational footprint
Large logistic and mobilization effort   Install and retrieve with a slickline unit and a crane

Permanent Magnet Motor

The AccessESP PMM works with any supplier pump and surface VSD system. Its significantly shorter length and lower weight for equivalent horsepower are key to slickline and riser retrieval/running.

Side Pocket Wet Connect System

The wet connect system and cable to surface are run on the packer/production tubing and form part of the permanent completion. The electrical connection is in a side pocket, designed to mitigate debris risk and enable full bore access when the pump/motor are pulled.

The current generation system has been developed with major operators and has been in use since 2014, proven reliable with multiple interventions.

In parallel with the PMM, an encapsulated power cable has been developed, with superior features and capabilities over its conventional ESP counterpart.
