The application of Electric Submersible Pumps to facilitate well production is a long established production technology; however, the onerous requirements of offshore environment makes the current ESP technology and the associated business model not fit to meet these challenges. An enabling technology for those deep water fields, where physical constraints of gas lift starts to be very challenging and for a drastic improvement of reliability in exisiting offshore fields, is what is needed. A Statoil development for a high speed ESP (AESP) is ongoing to primarily re-design the current machinery arrangements so that many of the key failure modes are eliminated and to tailor the design to high value wells, using an engineered approach.

The AESP development focuses on 6000 rpm high speed motor and pump technologies, introduces a seal-less coupling between pump and motor, to build a robust artificial lift system.

The goal is to develop an ESP system with 90% survival probability at 5 years.
