    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.

    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.

    Abstract: An apparatus for use in a wellbore. The apparatus includes a body and a blade assembly. The blade assembly is movable between a collapsed position whereby the expandable apparatus has a smaller outer diameter and an expanded position whereby the expandable apparatus has a larger outer diameter. The apparatus further includes a pressure activated member for selectively allowing the blade assembly to move from the closed position to the open position. A method for using the apparatus, wherein a drill string with an expandable bit at the end thereof is lowered into the wellbore. Thereafter, the pressure activated member is activated to allow the cutting members to move from the collapsed position to the expanded position. Subsequently, the expandable bit is rotated to form a portion of the wellbore. Next, the expandable bit is deactivated and the cutting members are moved from the expanded position to the collapsed position.
