Abstract: Embodiments of the present disclosure provide combined multi-coupler assembly for quickly connecting a top drive to a tool. The combined multi-coupler assembly includes a drive stem and a tool dock that may be coupled to each other. When the drive stem and the tool dock are connected, axial loads, torsional loads, and hydraulic, pneumatic, electrical, optical, or other types of communications may be transferred between the drive stem and the tool dock.

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.

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.

Abstract: A method and apparatus for connecting threaded members while ensuring that a proper connection is made. In one embodiment, the applied torque and/or rotation are measured at regular intervals throughout a pipe connection makeup. When a shoulder contact is detected, a predetermined torque value and/or rotation value is added to the measured torque and/or rotation values, respectively, at shoulder contact and rotation continued until this calculated value(s) is reached.
