Abstract: The present invention relates to a system for transferring signals through a drill pipe system during drilling of a subsurface well. The drill pipe system comprises a first pipe (1) provided concentric inside a second pipe (2) by means of hanging devices (3, 3a). The first pipe (1) is electrically insulated from the second pipe (2). A first signal transceiver is electrically connected to the top of the drill pipe system. A second signal transceiver is electrically connected along or in the bottom of the drill pipe system. The first and second signal transceivers are electrically connected to the first and second pipes (1, 2) for transferring the signals through the drill pipe system.

Abstract: A dual drill string valve includes an actuator including a piston disposed in a housing. The housing is configured to couple at its ends to an end of a nested dual drill string segment. An upper internal conduit is mounted in the housing proximate one longitudinal end thereof. A lower internal conduit is mounted in the housing proximate the other longitudinal end thereof. The piston is slidably, sealingly engaged between the upper and lower inner conduits and defines a fluid flow passage therethrough. The upper inner conduit, the piston and the lower inner conduit define another flow passage between respective exterior surfaces thereof and an interior of the housing such that application of fluid pressure to the external flow passage causes movement of the piston away from the upper inner conduit. A rotary valve is coupled to the actuator whereby longitudinal movement thereof rotates the rotary valve.

Abstract: A seal assembly for a nested dual drill pipe includes a tube having a female seal assembly and a male seal assembly at the longitudinal ends. The female seal assembly includes a larger internal diameter portion, a taper adjacent thereto and a smaller internal diameter portion adjacent to the taper. The male seal assembly includes a smaller external diameter portion, a seal groove adjacent thereto and a larger external diameter portion adjacent to the seal groove. The smaller internal diameter portion and the larger external diameter portion have diameters selected to enable free longitudinal movement of the male seal assembly into the female seal assembly while limiting axial displacement to maintain the seal ring fully energized.
