| 1. A method for achieving a monodiameter wellbore extending through various formations, the method comprising:
extending a work string into the wellbore, the work string having a bottomhole assembly;
flowing drilling fluids through the work string and bottomhole assembly;
drilling the wellbore using an extended gauge drilling member to minimize spiraling of the wellbore;
sending to the surface real-time downhole information from a measurement while drilling tool, a logging while drilling tool,
and one or more sensors in the extended gauge drilling member tool;
altering the direction of drilling based on the real-time downhole information using a directional steering assembly; and
chemically casing the wellbore.
