Abstract:
A stabilizer for a pipe being removed from a well comprises a body formed of body segments where the body segments are separable to allow the body to open and be wrapped around the pipe. The stabilizer has a first annular seal formed by first seal elements within the body for receiving and stripping the pipe, and may have a second annular seal. The body segments may be hinged together about a hinge that may be configured to limit the movement of the body segments relative to each other. The hinge may comprise an interdigitated first and second row of fingers.
