Abstract
Embodiments of a downhole drilling assembly generally include rotatable upper and lower drilling assemblies, and a drill bit, wherein an upper drilling assembly contains a mud motor adapted for clockwise stator rotation and counter-clockwise rotor rotation, whereby a lower drilling assembly is rotatable in the opposite direction of the upper drilling assembly or maintainable in a non-rotating state. The apparatus further includes sensors for continuously transmitting information relating thereto to the surface. Embodiments of a downhole clutch joint generally include a box end sub, a pin end sub, and a ratchet sleeve system containing a clutch joint mechanism, wherein the downhole clutch joint prevents rotation of a downhole drilling assembly in an undesired direction. Method embodiments generally include continuously measuring physical properties and/or drilling parameters, continuously transmitting information relating thereto, and controlling lower drilling assembly rotation in a non-rotating state or in the opposite direction of an upper drilling assembly.
