    Abstract: A method and apparatus for a drilling with casing includes therewith a drill shoe (10) configured for later drilling through thereof in situ, with cutter s retainable thereon in response to the forces encountered during borehole drilling, yet moveable from the envelope through which the later drill shoe will pass when cutting through the in situ drill shoe (10). The drill shoe (10) includes one or more profiles thereon, into which blades (26) carrying the formation drilling cutters are disposed. The profiles include at least o ne projection thereon, which is received within a mating slot in the blades. Th e blades (26) also may be configured to have opposed sections which are configured with respect to one another to have an included angle (136) of le ss than ninety degrees.

    Abstract: The present invention generally relates to an apparatus and method for expanding a tubular body in a wellbore. In one aspect, a method includes running the tubular body into the wellbore, the tubular body having a deformed portion. The method further includes reforming the deformed portion and positioning a two-position expander in the reformed portion. Additionally, the method includes shifting the expander to a second, larger diameter position and then expanding the reformed portion by urging the expander therethrough. In another aspect, a method for completing a wellbore is provided. In yet another aspect, a formable launcher section is provided. In a further aspect, a two-position expander tool is provided. In yet another aspect, an expansion system for use in completing a wellbore is provided.

    Abstract: A protection tool is provided to protect a control line in a safe area while one or more slips of a spider are being closed. In another embodiment, a safety interlock system is provided to prevent the closing of the slips before the control line is pulled away from the tubular string. In yet another embodiment, a safety interlock system includes a safety interlock trigger adapted to be actuated by a protection tool. The safety interlock trigger is adapted to detect the physical presence of the protection tool, and thereafter send a signal to the interlock system to enable an operator or a control mechanism to safely close the slips.
