  • Publication number: 20120031628
    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.

  • Publication number: 20110017474
    Abstract: Apparatus and methods are provided to prevent an operator from inadvertently dropping a string into a wellbore during assembling and disassembling of tubulars. In one embodiment, 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: 7861618
    Abstract: A method of coupling a tool to a length of tubular comprises securing the tool in a basket; lowering a tong arrangement having a rotary part and a stationary part, relative to the basket to engage respective locking members of the tong arrangement and the basket, thereby fixing the basket and the tool relative to the stationary part of the tong arrangement; and rotating the length of tubular using the rotary part of the tong arrangement so as to couple the tool to the length of tubular. A torque measuring flange may be associated with the tong arrangement. The torque measuring flange comprises a top plate and a bottom plate and one or more cylinders disposed between one or more wedges, whereby rotating the top plate causes the wedges to compress a piston in the cylinder.
