AccessESP Technology Demonstrates Reliability in Harsh Environments in Alaska


HOUSTON, Mar 15, 2018—An Alaska North Slope well initially completed in 2014 recently had its third slickline change-out of the ESP pump. The two previous slickline change-outs of the pump were performed in 2015 and 2016 for the same reason; degraded production performance due to abrasion by the produced fluids.

Surface diagnostics determined that the AccessESP downhole electrical component part of the permanent completion and retrievable PMM were fully functional. This meant that the permanent completion part of the Access375 system and retrievable permanent magnet motor (PMM) would remain in the well. The slickline operation to change-out the pump was completed in two days through a live well intervention using a lubricator and crane.

The Access375 system continues to operate reliably and has exceeded the average run life for the an ESP system in this well. This has enabled the operator significant savings in workover costs and deferred production by using slickline instead of a rig intervention.

“We continue to be pleased with the performance of the Access375 system, in use since 2014. The electrical system and PMM continue with high reliability, limiting the intervention to a slickline pump change only, reducing cost and deferred production.” said David Malone, AccessESP President & CEO. “We look forward to continuing to help our customers maximize the value of their ESP wells.”
