Abstract: Automated control of a drillstring in a borehole, which is not in continuous rotation, the drillstring comprising an angled component (a bent sub or the like) and a downhole means of rotating the bit, such as a motor or turbine, which rotates the bit independently of drillstring rotation. Near the distal end of the drillstring are measurement devices, at least one and in some aspects two or more, which are used to measure the orientation of the drillstring/bent sub/bottomhole assembly/drill bit with respect to a geophysical field of the earth, such as magnetism (magnetic toolface) or gravity (gravitational toolface). These measurement devices may be connected to a communications module which transmits the downhole toolface information to the surface. The drillstring is controlled to provide that based upon the downhole measurements the drilling system drills the borehole in a desired trajectory.

Abstract: A system and method is provided for drilling a wellbore including a rotary drill bit with a bit body having a plurality of mechanical cutters to cut away formation material as the wellbore is formed; and a directed energy mechanism to direct energy into the formation such that energy from the directed energy mechanism causes fracturing of surrounding material to facilitate drilling in the direction of the directed energy. The energy from the directed energy mechanism is used to enhance the cutting of the mechanical cutters by fracturing surrounding material to facilitate drilling in the direction of the directed energy.

Abstract: A drillstring comprising a length of drillpipes and a bottomhole assembly disposed at a downhole end of the length of drillpipes. The bottomhole assembly comprises a transition section proximal to the end of the length of drillpipes to reduce vibration of the bottomhole assembly during drilling. The transition section varies gradually in acoustic impedance between the acoustic impedance of the drillstring above the transition section and the acoustic impedance of the bottomhole assembly below the transition section. The transition section forms at least thirty percent (30%) of the total length of the bottomhole assembly.

Abstract: Resuming communication along a wellbore after a drilling stand or other occurrence that reduces the flow rate of the drilling fluid into a borehole being drilled in a drilling procedure or causes perturbations in the pressure of the drilling fluid in the borehole by measuring a first flow rate of drilling fluid being pumped into the drillstring during the drilling procedure before adding a section of drill pipe to the drillstring or before the pressure perturbation and increasing the flow rate of the drilling fluid being pumped into the drillstring above the first flow rate after the section of drill pipe has been added to the drillstring or the pressure perturbation has occurred.
