Abstract:

A dual-flow valve includes an inner valve body defining a first flow path and an outer valve body circumscribing the inner valve body. The outer valve body and the inner valve body define a second flow path. The dual-flow valve includes a valve element disposed across the first flow path and the second flow path. The valve element has a first passage for selective flow alignment with the first flow path and a second passage for selective flow alignment with the second flow path. A dual flow swivel includes an upper and lower swivel body, with the lower body adapted to rotate relative to the upper body. Two separate flow paths extend through the swivel bodies allowing upwardly and downwardly directed flows through the swivel bodies.

Abstract:

A system and method for communicating with a drill string is provided. The system may have an apparatus including a coupler, a frame and an actuator. The coupler may be operatively connectable to a surface system and a downhole system for communication therewith. The frame may be for supporting the coupler and may be operatively connectable to a handling system. The actuator may be for moving the frame with the coupler between an engaged position operatively connected to an uppermost drill pipe of the downhole system and a disengaged position a distance from the uppermost drill pipe whereby the coupler selectively establishes a communication link between the surface system and the downhole system.
