Bearings for SAGD Wells
With technological advances in steam-assisted gravity drainage (SAGD), electric submersible pumps (ESPs) are operating at higher temperatures and placing increased demands on the thrust bearings in the seal/protector section and motor.
To sustain high load capacity at these high temperatures, Waukesha Bearings offers the Hidrax™ HT thrust bearing.
Robust Bearing Material
Hidrax HT bearings feature hard ceramic or ceramic-metallic composite (cermet) materials that can retain their surface hardness at oil bath temperatures of 300°C (572°F) and higher. The rated unit load of the Hidrax HT thrust bearing is 8 MPa (1160 psi).
The design uses the well-proven Hidrax platform, with durable ceramic/cermet lining on the tilting pads and the thrust collar.
The superior strength and hardness of ceramic/cermet materials also provide the ability to crush abrasive debris that may enter the system through damage to a mechanical seal or contamination of the lubricating oil.
- Rated maximum oil bath temperature of 300°C (572°F)
- Rated bearing unit load of 8 MPa (1160 psi)
- Tungsten carbide lining
- Sizes up to 200 mm (8″)
- Center or offset pivot
- Drop-in replacement option
Thrust Bearings for ESPs
Waukesha Bearings offers a range of material options to maximize thrust bearing life in electric submersible pumps (ESPs), increasing efficiency, production and the operating life of the pump.
Intro to Bearing Materials
The selection of the bearing materials plays a significant role in the performance of fluid film bearings. Load, speed, operating temperature, insulation requirements, and lubricant type and cleanliness may all play into the material choice.
