  • Method of controlling torque applied to a tubular connection
    Patent number: 8297347
    Abstract: Embodiments of the present invention generally relate to a method for controlling the torque applied to a tubular connection. In one embodiment, a method of connecting a first threaded tubular to a second threaded tubular supported by a spider on a drilling rig includes engaging the first threaded tubular with the second threaded tubular; making up the connection by rotating the first tubular using a top drive; and controlling unwinding of the first tubular after the connection is made up.
    Type: Grant

    Date of Patent: October 30, 2012
    Assignee: Weatherford/Lamb, Inc.
    Inventors: Graham Ruark, Merlin Perry, Aaron Dauphine
  • System and method for deflection compensation in power drive system for connection of tubulars
    Patent number: 8167038
    Abstract: The present invention generally provides methods and apparatus for connecting threaded members while ensuring that a proper connection is made, particularly for premium grade connections. In one embodiment, a method of connecting threaded tubular members for use in a wellbore or a riser system is provided. The method includes the acts of operating a power drive unit, thereby rotating a first threaded tubular member relative to a second threaded tubular member; measuring the rotation of the first threaded tubular member; and compensating the rotation measurement by subtracting a deflection of at least one of: the power drive unit, and one of the tubular members.
