Artificial Lift Systems for Harsh Environments
Optimize ESP performance under standard, harsh, and extreme duty conditions.
The environment and conditions under which ESPs must perform vary widely and can be challenging. Wells producing:
- With high (GOR) gas content
- Abundant solids and abrasive particles
- High viscosity fluids
- Corrosive fluids
- With scale and other precipitates
- At higher temperature
present an increasingly harsh environment for ESP operations as concentrations or levels of these conditions rise. Borets ESP systems overcome harsh environment challenges through the combination of product engineering, material selection, application design, and operational methods to optimize performance under standard, harsh, and extreme duty conditions. Aflas O-rings are standard in all products across each duty level.
All Borets pumps are built to ISO 9001:2015 and API Spec Q1 standards.
Standard Duty (SD)
Borets SD ESP systems include standard construction floater and compression pumps using carbon steel heads and bases, housings, and compression nut.
The SD ESP system is recommended when:
- Produced gas volumes are low.
- Produced solids are negligible or in low concentration (smooth sand with low quartz content) and have only mild impact on equipment wear.
- Corrosive fluids or gases (CO2 and H2S) are either absent or in very low concentrations.
- Bottomhole and operating temperatures are low.
Harsh Duty (HD)
The HD ESP system is recommended when:
- Produced gas volumes are mid-range to high.
- Produced solids and sand are noticeable, include particles of different shape and size with significant quartz content, and expected to have moderate impact on equipment wear.
- Moderate levels of CO2 and high levels of H2S are present.
- Bottomhole and operating temperatures are low to moderately higher.
Using gas separators is recommended when free gas will not exceed 72% by volume.
Borets XD ESP systems include compression pumps fitted with TC bearings in every diffuser and the option to use packet pumps fitted with TC bearings every third stage, high-temperature motors, metal bellows, and non-elastomeric motor seals.
The XD ESP system is recommended when:
- Produced gas volumes are high
- Produced solids and sharp sand particles with high quartz content are very abundant and have aggressive impact on equipment wear
- High levels of CO2 and moderate levels of H2S are present
- Bottomhole and operating temperatures are low
Use of the Vapro multiphase gas handler in combination with vortex gas separators is recommended when free gas is present up to 90% by volume.
