Patent number: 7654158Abstract: Apparatus and methods for measuring in-situ applied torque in tubular operations. A torque cylinder has a first end and a second end. A torque rod is at least partially contained in the torque cylinder and is coupled to the first end of the torque cylinder. The torque rod extends longitudinally outward from the second end of the torque cylinder. A strain gauge is connected to the torque rod at a predetermined distance from the first end of the torque cylinder.

Publication number: 20090090555Abstract: Methods and systems for drilling to a target location include a control system that receives an input comprising a planned drilling path to a target location and determines a projected location of a bottom hole assembly of a drilling system. The projected location of the bottom hole assembly is compared to the planned drilling path to determine a deviation amount. A modified drilling path is created to the target location as selected based on the amount of deviation from the planned drilling path, and drilling rig control signals that steer the bottom hole assembly of the drilling system to the target location along the modified drilling path are generated.Type: ApplicationFiled: September 19, 2008Publication date: April 9, 2009Applicant: Nabors Global Holdings, Ltd.Inventors: Scott Gilbert BOONE, Brian Ellis, Colin Gillan, Beat Kuttel
