Video Unveiling the Most Energy-Efficient ESPCP for Any API Gravity
New innovative ESPCP system lifts low flow rate production of any API gravity more reliably and sustainably.
ESPCP rodless lift of any fluid at lower power consumption
Reda PowerEdge energy-efficient wide-range ESPCP system
Overview
Lift better rodless
The Reda™ PowerEdge™ energy-efficient wide-range ESPCP system gives operators a more efficient and reliable alternative to rod lift systems (also called sucker rod pumps) typically used for the lower production rates of mature wells. This approach to rodless lifting gives operators an extended operational range for optimizing production, including light API gravity oils and at temperatures up to 250 degF [121 degC]. The high-efficiency performance of both the ESPCP system’s innovative pump redesign and high-performance permanent magnet motor (PMM) lowers energy consumption to also reduce related CO2 emissions.
Applications

- Heavy, medium, and light oil; coal seam gas; and coalbed methane (CBM)

FAQs
What is the primary benefit of replacing rod lift?
By eliminating the use of sucker rods in a well, the PowerEdge ESPCP system removes the cause of up to 80% of rod lift system failures from holes in the tubing and parted rods. In turn, operators avoid the required workovers and production deferments that resulted.
How do maintenance requirements for rod lift and the PowerEdge ESPCP system compare?
The high-reliability pump and motor of the PowerEdge ESPCP system require far less routine maintenance than the components of a rod lift system.
What is the expanded lift application provided by the PowerEdge ESPCP system?
Rod lift systems typically encounter difficulties when used in deep, highly deviated wells with solids and high gas content. The PowerEdge ESPCP system simplifies installation in wellbore geometries that limit rod lift access and functionality. The new PCP stator elastomer and design make the system compatible with any API gravity oil and at temperatures up to 250 degF. The ESPCP system can handle high solids content and GVF without experiencing gas locking.
How does the pump redesign contribute to ESPCP system reliability?
The pump of the PowerEdge ESPCP system incorporates a composite stator that delivers high-reliability performance:
- SLB developed and patented a new manufacturing process.
- Elastomer viscosity is 4× higher than the standard elastomer.
- Elastomer chemical structure is more resistant to aromatics.
- Even and thin elastomer design results in uniform elastomer swelling with better heat dissipation.
- New chemical bonding replaces traditional adhesive (glue).
The system’s hollow rotor enables the pump to rotate reliably at higher speeds because its lighter weight significantly reduces vibration, which can also shorten pump life. This access to higher operating speeds supports the pump’s expanded operating range.
Why does the ESPCP system use a PMM?
The field-proven PMM powering the PowerEdge ESPCP system delivers constant torque across the system’s entire recommended speed range of 100 rpm to 1,000 rpm. This capability eliminates the need for a mechanical gear reducer, which can be an unreliable component and prone to early failure.
How does changing out an ESP with a PowerEdge ESPCP system save on installation costs?
Installation costs are minimized for the surface components when a PowerEdge ESPCP system replaces an ESP. Existing ESP surface equipment and downhole cables can be reused, and the PMM of the ESPCP is compatible with most third-party variable speed drives (VSDs). This technology alignment also negates the need for extensive civil work at the wellsite for conversion from ESP lift.
What makes the PowerEdge ESPCP system a more sustainable option than rod lift?
This more efficient lift system consumes up to 55% less power than rod lift to similarly reduce related CO2 emissions.
How does the PowerEdge ESPCP system improve drawdown potential?
Because the PowerEdge ESPCP system does not use rods to power the pump, the entire system is significantly shorter. These differences in configuration and length mean the ESPCP system does not have the same well depth and deviation limitations as rod lift. It can be installed farther into the well, closer to the producing zone, to improve drawdown potential.
The innovative pump of the PowerEdge energy-efficient wide-range ESPCP system pairs a composite stator with a hollow rotor to increase lift reliability and efficiency.
