Paper presented at the SPE Gulf Coast Section Electric Submersible Pumps Symposium, October 4–8, 2021
Paper Number: SPE-204521-MS
... Abstract SAGD ESPs run at the highest motor temperatures current technology allows. However, they cool very rapidly when shutdown. High cooling rates promote motor oil volumetric contraction, eventually leading to wellbore fluid ingress and short-circuited motors. The Paper presents successful...

Paper presented at the SPE Gulf Coast Section Electric Submersible Pumps Symposium, October 4–8, 2021
Paper Number: SPE-204508-MS
... Abstract Electrical submersible pumps (ESPs) are closely monitored in surveillance operations because they operate in challenging environments and are subject to stressful events that, if left without intervention, may lead to unplanned shutdowns, decreased run life, or even failures...

Paper presented at the SPE Gulf Coast Section Electric Submersible Pumps Symposium, October 4–8, 2021
Paper Number: SPE-204483-MS
... Abstract Build a more robust ESP or reduce the stress it endures? Run-life improvement requires finding the right balance to suit the local well conditions and economics. Utilizing key case studies, the paper examines how operational stress caused by low flow rates can be avoided...
