Background
To efficiently produce from a well, an operator in Canada needed to pump a high-temperature steam into the reservoir to decrease fluid viscosity enough to enable its movement toward the wellbore. However, the high temperatures that occur during SAGD operations can compromise ESP run life. With the reservoir recovery ratio dependent on the high injection temperature, the operator asked Schlumberger for a high-reliability solution that would improve recovery without compromising run life.

REDA Hotline System Increases Run Life by an Average of 445%

High-temperature ESP system improves recovery and reliability in steam-assisted gravity drainage (SAGD) well

Schlumberger installed the Hotline ESP system with a high-temperature non-weather-dependent integrated motor with downhole monitoring gauge. The integrated motor features a full protector and compensation system configured for immediate deployment in the well, eliminating human error and saving rig time during assembly. The system was installed with a bottom-feeder gas separator along with an AGH device. The Hotline system increased run life by an average of 445% and is still running. This improved the customer’s total cost of ownership by eliminating unnecessary workovers and deferred production.
