  • Re-settable and anti-rotational contraction joint with control lines
    Patent number: 8061430
    Abstract: A downhole contraction joint. The downhole contraction joint can include at least one anti-rotation assembly. The anti-rotation assembly can include a first tubular member at least partially disposed within a second tubular member. An axial slot can be formed through at least a portion of the first tubular member, and at least one key can be at least partially disposed within the second tubular member and the axial slot. The downhole contraction joint can also have at least one resetting assembly disposed at a first end of the anti-rotation assembly. The resetting assembly can include a c-ring secured to the second tubular member. The first tubular member can be secured to the lock ring, and the lock ring can be aligned with the c-ring. The downhole contraction joint can also include at least one control line assembly disposed about a portion of the anti-rotation assembly.
