  • Patent number: 8485067
    Abstract: An apparatus for connecting tubulars comprises tongs for gripping the tubulars, having openings which can be aligned to allow tubulars to enter the tongs, and a detection apparatus for detecting the location of a joint between the tubulars. The detection apparatus comprises a set of keys disposed along an axis substantially parallel to the axis of the tubulars, the keys being individually displaceable on contact with the tubulars as the tubulars enter the tongs through the openings. The detection apparatus further comprises a set of sensor means, each arranged to detect displacement of a corresponding key. The position of the joint can then be determined from the displacement of the keys.

  • Patent number: 8356675
    Abstract: Apparatus and methods used to prevent an operator from inadvertently dropping a string into a wellbore during assembling and disassembling of tubulars. In one instance, an interlock system is used to control the operations of a gripping apparatus connected to the top drive and a spider such that at least one of the top drive or the spider retains the tubular. The interlock system allows the spider to open when the gripping apparatus is supporting a load of the tubular or is in position to support a load of the tubular.

  • Patent number: 8281856
    Abstract: A torque sub for use with a top drive is disclosed. A method of connecting threaded tubular members for use in a wellbore includes operating a top drive. The top drive rotates a first threaded tubular member relative to a second threaded tubular member. The method further includes measuring a torque exerted on the first tubular member by the top drive. The torque is measured using a torque shaft rotationally coupled to the top drive and the first tubular. The torque shaft has a strain gage disposed thereon. The method further includes wirelessly transmitting the measured torque from the torque shaft to a stationary interface; measuring rotation of the first tubular member; compensating the rotation measurement by subtracting a deflection of the top drive and/or the first tubular member; determining acceptability of the threaded connection; and stopping rotation of the first threaded member when the threaded connection is complete or if the threaded connection is unacceptable.
