... (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 failure rates in certain applications, resulting in significant impacts on overall ESP system reliability...

... 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...

... companies develop procedures to re-use the most significant components of an Electrical Submersible Pump (ESP) system. These include the pump, cable, seal chamber section, and motor. The motor stator, bearings, and rotors are a high percentage of reclaimable parts in an ESP system. Reclaiming the induction...

... industry documents that provide some level of guidance on seal/protector sections. These documents refer to these components as "seal chambers". This paper will use the terminology of "seal/protector" given the industry standard nomenclature. The two documents are detailed below. American Petroleum...

... tandem sections of seals have been standardized each with a minimum of two Aflas bags (four in total per system) in series in addition to any labyrinth chamber. Examples of seal bags are shown in Figure 3 . Figure 3 Typical seal bag models from two different ESP vendors The seal bags have...

... be added to system, rather than undesirably reducing barrier component redundancy to have chambers communicate in parallel to gain capacity, for example. One historically common approach to mitigating a deficit of seal section adaptive capacity in multichamber seals, where multiple chambers have...

... 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...

... systems included damaged cables, broken Seal Chamber Section (SCS) and pump intake shafts, leaking mechanical shaft seals, broken or worn radial or thrust bearings, and short circuited motors (e.g. associated with stator/rotor contact). An analysis of the operators' most recent run-life data, plotted...

... assembly was successfully designed, sourced, manufactured, installed, and operated. To modify the design from vertical to horizontal applications, components were custom-designed to maintain a sealed chamber. Components deemed most likely to fail are replaceable by slickline intervention. Results indicate...

... Abstract Electric submersible pumps (ESPs) are used in oil production as effective means of artificial lift. All the major componets of an ESP are put in a long and slender housing. Seal section, located between the motor and the pump, consists of a number of chambers. All the chambers...

.... However this level is difficult to achieve and higher levels can occur through both poor deaeration and air leakage into the plant. In the present test program the environment selected to simulate MSF plant conditions is synthetic sea water (DEF1053/B.S.3900/B.S.2011) at 90°C in a sealed environment...
