Rod string
PCM supplies a complete range of products suitable for your rod string completion.
PCM provides conventional sucker rods, polished rods, couplings & centralizers for various applications. Selecting suitable rods can be critical to manage tubing wear, torsional strength and well geometry, which may have very high Dog-Leg Severity (DLS).
PCM also provides rods for high temperature application requirements.
Polished rods
Ensure an appropriate sealing
Key features & benefits:
- Transmit sufficient torque to drive PCP
- Handle the complete rod string load
- Ensure sealing with Drivehead sealing device
- Ensure Flush-By operation (thanks to Polished Rod longer than downhole Rotor)
- 11 to 44 ft length
- 1”¼, 1”½ and other size available on request
Sucker rods
Handle torque and weight
Key features & benefits:
- Deliver sufficient torque to drive PCP
- High strength sucker rod available
- High Alloy sucker rods available for corrosive environment (option)
- Pony rods allow to adjust the rod string length to ensure the correct position of the rotor and suitable polished rod stick-up
- Size adapted to torque requirements and tubing size.
- Grad D or high strength available
- ¾”, 7/8”,1”, 1”1/8, 1" 1/4, 1" 1/2
- Pony Rods to adjust string length (2,4,6,8,10,12 ft)
Couplings
Connect rod string elements
Key features & benefits:
- Polished rod to sucker rod
- Sucker rod to sucker rod or to centralizers
Centralizers
Prevent tubing wear
Key features & benefits:
- Non-rotating centralizers
- Spindle/sleeve type
- Available for high temperature (metallic sleeve)
- Protect the surface Drivehead from excessive rod vibrations
- Eliminate or reduce tubing wear and rod string wear
- Reduce torque especially in deviated wells
- Limit eccentricity vibration and propagation into the rod string
Advanced options
Continuous rods
For highly deviated well & faster RIH
Key features & benefits:
- High torque compatibility
- continuous design to reduce tubing wear
