Upon release of the stored potential energy the diameter of the spring grows so that contact of the surrounding tubular is made by the spring to at least in part support one string to another. Alternatively, the rotational force from unwinding the spring can drive a slip or other support member radially outwardly into contact with the surrounding tubular and if desired lock the gripping position between the tubulars. Unexpended potential energy of the unwinding spring can also be a residual force to hold the expanded spring to the surrounding tubular. The axial shrinkage of the coiled spring can also be deployed in actuation of the slip in conjunction with rotational movement to advance the slip radially for a grip of the surrounding tubular.

  • Patent number: 9022113
    Abstract: A tubular string is advanced with a bottom hole assembly as the hole is drilled and reamed in a desired direction with the aid of directional drilling equipment adjacent the bit. When the advanced tubular forms the desired lap to the existing tubular, the assembly can be configured to cement the tubular and expansion can then be accomplished to fill the annular space and enhance the cement bonding. The expansion equipment can create a bottom bell on the expanded tubular and expand the top end into a bell of the existing tubular so that a monobore is created as the process is repeated with each added string. Numerous variations are contemplated for each single trip including but not limited to the direction of expansion, whether cementing or expansion occurs first, reforming folded tubing in the hole as well as the nature of the expansion tool and pressure control when drilling.

  • Patent number: 8997856
    Abstract: The present invention provides a system for anchoring an expandable tubular to a borehole wall. The system comprises a support member having a first end fixed relative to the outside of the tubular and a second end comprising a ramping surface. An anchor member has a first end fixed relative to the outside of the tubular and a second end extending toward the support member, said second end being movable relative to the outside of the tubular. Said support member includes a ramp surface that tapers in the direction of said anchor member. Expansion of the portion of the expandable tubular between the first support end and the first anchor end causes the axial device length to shorten, wherein the difference in length is sufficient to cause the second anchor end to move radially outward and engage the borehole wall as a result of engagement with said ramping surface.
