    Abstract: Embodiments of the present invention generally relate to an earth removal member with features for facilitating drill-through. In one embodiment, an earth removal member for drilling a wellbore with casing or liner includes a tubular body and a head. The head is fastened to or formed with an end of the body, has a face and a side, is made from a high strength material, and has a port formed through the face. The earth removal member further includes a blade. The blade is formed on the head, extends from the side and along the face, and is made from the high strength material. The earth removal member further includes cutters disposed along the blade; and a nozzle adapter. The nozzle adapter has a port formed therethrough, is longitudinally and rotationally coupled to the head, and is made from a drillable material. The earth removal member further includes a nozzle disposed in the adapter port and fastened to the nozzle adapter.

    Abstract: Methods and apparatus are provided to place a conductor pipe and a casing in a subsea environment. In one embodiment, a conductor pipe is jetted or drilled into the subsea floor. Thereafter, a casing drilling assembly comprising a drill casing and a drilling assembly is connected to the drill pipe using a crossover. The drilling assembly urged into the seafloor until a casing latch on the drilling assembly is engaged with a casing profile of the conductor pipe. During drilling, instrumentation in the drilling assembly may be used to measure geophysical data. The measured data may be used to optimize the drilling process. After the drill casing is engaged with the conductor pipe, cementing may be performed to set the drill casing.

    IPC: E21B10/32

    Abstract: Embodiments of the present invention generally relate to extendable cutting tools for use in a well bore. In one embodiment, a tool for use in a wellbore includes a tubular body having a bore therethrough, an opening through a wall thereof, and a connector at each longitudinal end thereof; and an arm. The arm is pivotally connected to a first piston and rotationally coupled to the body, is disposed in the opening in a retracted position, and is movable to an extended position where an outer surface of the arm extends outward past an outer surface of the body. The tool further includes the first piston. The first piston is disposed in the body bore, has a bore therethrough, and is operable to move the arm from the retracted position to the extended position in response to fluid pressure in the piston bore exceeding fluid pressure in the opening. The tool further includes a lock operable to retain the first piston in the retracted position; and a second piston operably coupled to the lock.

    Abstract: In one embodiment, a method of forming a wellbore includes running a liner drilling assembly into the wellbore, the liner drilling assembly having a liner, a conveying member, one or more connection members, and a drilling member. The method includes temporarily suspending the liner at a location below the rig floor; releasing the conveying member and the drilling member from the liner; re-connecting the conveying member to the liner; releasing the liner from its location of temporary suspension; and advancing the liner drilling assembly.
