ABSTRACT OF THE DISCLOSURE In accordance with illustrative embodiments of the present invention, more accurate directional drilling is carried out by providing a downhole adjustable bent housing that is selectively operated to produce a bend angle in the drill string between a downhole motor and the drill bit, providing a near-bit stabilizer having a full gage condition and an undergage condition, and using the undergage condition of the stabilizer during sliding drilling, particularly when a bend angle is present, and the full gage condition of the stabilizer only when the drill string is rotated. Sensors are located above and below the bent housing to measure inclination and azimuth, and such measurements are telemetered to the surface during drilling for analysis.
