High Temperature Pump Testing

The High Temperature Flow Loop is used to carefully test the performance of downhole pumping systems over a range of operating temperatures, pressures, flowrates and gas/liquid ratios. 

This custom loop includes an 90 ft long, 244.5 mm OD (9 5/8", 40 lb/ft), casing section that’s orientated at 3° off horizontal to mimic a “typical” SAGD production well where the AL system can be positioned. 

Over the years the C-FER flow loop has been upgraded numerous times, and used to independently test the performance, reliability, and degradation of some of the newest forms of high temperature AL systems (e.g. most commonly ESP’s, MxM PCPs, PCPs, etc.) in the world. 

In many cases this has also included helping the vendors optimize the performance of their AL systems under these very challenging thermal conditions.





Physical Setup

  • 11" 3000# API wellhead flange which allows for a variety of standard wellheads to be installed
  • Fully instrumented to allow real-time pressure, temperature, power, and flow measurements, as well as variables like pump torque, speed, downhole vibration, downhole temperature distribution, ALR, GVF, and all relevant fluid properties – where in some cases C-FER has developed custom high temperature instrumentation to assist with these measurements
  • Allows for downhole gas (steam and air) separation at the pump intake with a simulated submergence of approximately 2m (6.6 ft)
  • C-FER can provide existing equipment (e.g. VFDs and drive-heads) to help lower setup costs, or (preferably) utilize a system entirely provided by the AL vendor.
