    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.

    Abstract: In one embodiment, there is provided a system for liner drilling in a wellbore that includes a drill bit, a mud motor, a reamer, a drill pipe work string including an expandable liner hanger running tool, and a thruster coupled to an expandable liner hanger and liner. A release pin may be provided in the expandable liner hanger running tool that can be sheared to de-couple the expandable liner hanger from the expandable liner hanger running tool allowing the drill pipe work string to be removed from the borehole while the liner remains in place. A latch coupling is also provided for coupling the expandable liner hanger running tool to the expandable liner hanger when the drill pipe work string is tripped back into the borehole so the liner drilling can be performed using the thruster until the thruster is at full stroke.
