APPLICATION:
- Vertical, directional and horizontal wells containing severe doglegs.
- Thermal wells with casing movements due to thermal expansion, contraction, and formation shifting and movements.
- Wells containing voids due to product removal, washing, and formation slumps.
FEATURES:
- Can be run with any casing types and connections. The RBC will be assembled within the casing string, using the same makeup values and equipment used as the liner run.
- Allows bending of the liner (RBC connection) up to 30° without damage to the liner.
- Allows rotation and bending of the RBC connection simultaneously, while holding a connection seal. It has equivalent axial, tensile and compressive strengths as the liner run.
- The load required to bend the RBC connection off its axis, is preset at surface.
BENEFITS:
- Can decrease the chance of liner failures due to, long periods of casing rotations, severe doglegs, formation shifting, thermal movements, and formation voids, both during and after installation.
- Control the loads required to allow bending of the RBC connections/casings down hole.
- Allow rotation of liner down hole where otherwise would cause connection failures (fatigue cracking in the casing connection threads).
