Electro-Submersible Pumps
Squeeze pumps cover a wide range of flow rates and are very tolerant of higher thrust loads and heavy solids in the produced fluids. Unlike floating pumps, compression pumps can better handle varying thrust loads in rapidly changing flow conditions, as is often the case with gas shocks.
When a compression pump starts to operate with downward thrust, the force is transferred and managed in the thrust bearing of the motor seal. Absorption of this downward thrust force in the clean oil environment of the seal section helps to extend pump life.
The Packet pump is better able to withstand the prolonged downward thrust and abrasive production that ESPs typically experience in unconventional well applications. The package pump is constructed so that as mechanical wear progresses, the stage impellers will lock in groups (configurable packages) to limit axial movement of the package along the shaft. Downward thrust is dynamically managed through a tungsten carbide bearing (T) in the diffuser at the base of each package.
The benefits of ESP design include:
- Increased production even in difficult environments
- Longer ESP life, improving ROI
- Wider pump operating range, reducing intervention costs
