METHOD AND APPARATUS FOR A MONODIAMETER WELLBORE, MONODIAMETER CASING, MONOBORE, AND/OR MONOWELL

摘要

An assembly and methods for constructing a MONOWELL includes a monodiamete r casing disposed in a monodiameter wellbore having diametric efficiency with a monobore production delivery system disposed within the monodiameter casing. An assembly for constructing a monodiameter wellbore includes a bottomhole assembly having a overgauge hole drilling member, a directional steering assembly, a measurement while drilli ng tool, and a logging while drilling tool; a work string attached to the bottomhole assembly and extending to the surface; drilling fluids flowing through the work string and bottomhole assembly; chemical casing casing the borehole; expandable casing disposed in the wellbore; and a sealing composition disposed between the expandable casing and the wellbore.
