Abstract

A method and apparatus for drilling and completing a bore hole are disclosed. The method comprises positioning a work string in the well, with a bottom hole assembly attached. The bottom hole assembly can include a drill bit, a drilling motor, orientation instrumentation, and a completion assembly. A fluid is circulated to drive the drill bit to drill the well to a target formation. Then, the completion assembly is used to produce fluids from the formation. Gravel packing can also be performed with the bottom hole assembly.
