Paper presented at the SPE Gulf Coast Section Electric Submersible Pumps Symposium, October 4–8, 2021
Paper Number: SPE-204494-MS
...Abstract Abstract Mechanical Shaft Seals (MSSs) are critical sub-components in Electric Submersible Pump (ESP) Seal Chamber Sections (SCSs), as they are the primary barriers used to isolate wellbore fluids from the motor oil. However, several ESP operators have observed relatively high MSS...

Paper presented at the SPE Gulf Coast Section Electric Submersible Pumps Symposium, May 13–17, 2019
Paper Number: SPE-194404-MS
... Abstract One of the main functions of an ESP Seal Chamber Section (also known as a "Protector") is to provide a rotating mechanical seal to protect the motor oil from contamination. These seals are susceptible to damage due to a high concentration of fines in production fluids scoring...

... is being covered in the new international standard for ESPs (ISO 15551-1). The ISO ESP committee has been working hard over the past 11/2 years to draft a standard that contains requirements for pumps, gas handlers, intakes, mechanical gas separators, cables and motor-lead extensions, seal-chamber sections...

... in the electrical components and sub-components, including the motor. It is unclear, however, how big of an impact this would have in the motor reliability, and therefore how much of a concern this should be. Seal Chamber Section The main concern with this component is related to the leakage through the mechanical...
