Abstract: A drill pipe includes a pin end connector, a box end connector, a first communication connector and a second communication connector. The pin end connector includes a first region to form a threaded connection to join sections of the drill pipe together, and the first region includes at least one thread that begins at one end of the first region and ends at the other end of the first region. The box end connector receives the pin end connector, and the box end connector includes a second region to mate with the first region to form the threaded connection. The first communication connector is attached to the pin end connector and is located in the first region; and the second communication connector is attached to the box end connector and located in the second region to form a communication connection with the first communication connector.

Abstract: A downhole tool string component has at least one end adapted to connect to an adjacent tool sting component and a bore adapted to accommodate a flow of drilling fluid. A turbine is disposed within the bore and an actuating assembly is arranged such that a clutch may mechanically connect and disconnect with the turbine.

Abstract: In one aspect of the invention, a downhole tool string component has at least one end adapted to connect to an adjacent tool sting component and a bore adapted to accommodate a flow of drilling fluid. A turbine is disposed within the bore and an actuating assembly is arranged such that a clutch may mechanically connect and disconnect with the turbine.

Abstract: A tool comprising a fluid path defined by a bore formed within a tubular body includes a guided sleeve and a reciprocating sleeve disposed within the bore. A gearwheel is located on an outer surface of the guided sleeve and at least one pawl located on an inner surface of the reciprocating sleeve. When the reciprocating sleeve translates axially, it rotates in a first direction. As the reciprocating sleeve rotates, the at least one pawl pushes the gearwheel and causes the guided sleeve to rotate in the first direction into a new position.

Abstract: A wellbore perforation tool comprises an explosive charge, a tool body containing the explosive charge, and a flowable material carried with the tool. The flowable material is released by detonation of the explosive charge and, after perforation of the tool body by the explosive charge to form an aperture in the tool body, flows to form at least a partial barrier of the aperture.

Abstract: A shaped charge assembly for use in a perforating gun that further comprises a charge carrier, and gun housing. The charge carrier substantially encapsulates the closed portion of the shaped charge and extends from the outer periphery of the shaped charge to the inner diameter of the associated gun housing. Encapsulating the shaped charge substantially reduces the introduction of debris into the wellbore resulting from detonation of the perforating gun shaped charges. The charge carrier can include a multiplicity of shaped charges therein.

Abstract: A packer tool for use in a wellbore having a bottomhole pressure p, includes: a mandrel assembly; a stabilizer on the mandrel assembly, for releasably engaging the wellbore; a packing element in an annular recess having a floor and two facing walls, the annular recess being transversely compressible into a compressed position and disposed about the mandrel assembly; and a piston assembly for driving compression of the packing element annular recess. The piston assembly has a plurality of piston faces moveable together in the same direction, the plurality of piston faces having a total piston face surface area a such that an application of pressure of p? to the piston assembly generates a force f greater than p.

Abstract: High productivity core drilling systems include a drill string, an inner core barrel assembly, an outer core barrel assembly, and a retrieval tool that connects the inner core barrel assembly to a wireline cable and hoist. The drill string comprises multiple variable geometry drill rods. The inner core barrel assembly comprises a non-dragging latching mechanism, such as a fluid-driven latching mechanism that contains a detent mechanism that retains the latches in either an engaged or a retracted position. The inner core barrel assembly also comprised high efficiency fluid porting.
