Patent ID: 7926578

Claim:
A method of drilling a well and installing a liner, comprising: (a) assembling concentric inner and outer strings of tubulars to define a concentric string assembly, the inner string including a bottom hole assembly axially and rotationally latched to the outer string, the outer string including a string of liner; (b) connecting a running tool to the liner, and with the running tool, lowering the concentric string assembly into a well from a drilling rig, and rotating a drill bit at a lower end of the bottom hole assembly to deepen the well; (c) prior to reaching a total depth for the string of liner, raising the concentric string assembly and supporting an upper end of the outer string at the drilling rig with a slip assembly at a rig floor such that the running tool is located above the rig floor; (d) while the upper end of the outer string is supported at the drilling rig, removing the running tool, then retrieving a remaining portion of the inner string and the bottom hole assembly from the outer string; and (e) re-running the bottom hole assembly on the inner string into the outer string and axially and rotationally re-latching the inner string to the outer string to again define the concentric string assembly, reconnecting the running tool to the liner, lowering the concentric string assembly back into the well, and again rotating the drill bit to deepen the well.
