An electric submersible pump (ESP) is a high-volume pump used in offshore, harsh and environmentally sensitive locations. However, with a typical two-year run life, an electric submersible pump’s potential in offshore and remote locations is limited by the requirement for rig mobilization for any intervention. Using a rig to intervene means incurring high costs and deferred production and needing to pull the production tubing to access the reservoir.
ESPs are seldom replaced unless they have failed. Meanwhile, production rates typically fluctuate and the production composition may also change from mostly oil to a mixture of oil and water. This means that for most of the pump’s life, it won’t operate in an optimal range but at a point that’s a compromise between the total flow rate and the life of the pump.
With AccessESP, you can retrieve the electric submersible pump at any time to optimize it for the current known well conditions, while leaving the motor in the well. Therefore, the pump can operate at a higher level of efficiency based on the actual well conditions. This affords the operator an optimized pump design with reduced lifting costs and a longer pump run life.
