AccessESP Delivers Cost-Effective Pump Replacement Solution

AccessESP, the provider of rigless electric submersible pump (ESP) conveyance solutions, has showcased its rigless ESP conveyance system in the industry’s first pump swap for an operator on the North Slope of Alaska.

In two days, through a live well intervention, the AccessESP system enabled retrieval of the existing ESP pump and the install of a newly optimized ESP pump using only a slickline unit, lubricator and a crane, marking the industry’s first ESP pump swap on a commercial well.

Surface diagnostics determined that the Access375 permanent magnet motor was fully functional and did not require replacement.

In this case, the ESP pump had not failed but was proactively replaced with an optimized pump. By utilizing a standard slickline unit, lubricator and crane, the AccessESP rigless conveyance system reduced the cost, time and risk associated with ESP resizing, the company said.

Greg Nutter, vice president operations, AccessESP, said: “In this project, the operator saved approximately $2 million in workover costs by using our slickline deployed system. Our system allows the operator to replace only the ESP pump, leaving the permanent magnet motor in the well. This pump replacement demonstrates our system is a flexible and reliable choice for operators looking to optimize production and reduce downtime and associated costs.”
