Abstract: A fluid pressure pulse generator apparatus for a telemetry tool comprising a stator and a rotor. Rotor projections are axially adjacent and rotatable relative to stator projections between an open flow position where the rotor projections axially align with the stator projections and a restricted flow position where the rotor projections axially align with the stator flow channels to create fluid pressure pulses in fluid flowing through the stator flow channels. At least one uphole radial face comprises a stopper portion which is uphole relative to at least a portion of the axially aligned downhole radial face and/or at least one downhole radial face comprises a stopper portion which is downhole relative to at least a portion of the axially aligned uphole radial face, such that the stopper portion limits the span of rotation of the rotor relative to the stator.

Abstract: A telemetry method transmits data by MP telemetry to a telemetry relay system which retransmits the data by EM telemetry. The method avoids the need to incorporate MP telemetry pressure transducers into rig equipment and permits telemetry from regions unfavourable for EM telemetry because of depth and/or characteristics surrounding formations.

Abstract: An assembly for use in subsurface drilling includes a downhole probe having an EM telemetry signal generator and electrical contacts for carrying telemetry signals from the EM telemetry signal generator to first and second parts of a gap sub in a drill string. An outside surface of the probe and an inside surface of the gap sub are covered with layers of electrically-insulating material. Electrical conduction paths internal to the gap sub are removed, thereby increasing efficiency of EM telemetry.

Abstract: A fluid pressure pulse generator apparatus for a telemetry tool comprising a stator and a rotor. The stator comprises a stator body and a plurality of radially extending stator projections spaced around the stator body and the spaced stator projections define stator flow channels extending therebetween. The rotor comprises a rotor body and a plurality of radially extending rotor projections spaced around the rotor body. The rotor projections are axially adjacent the stator projections and the rotor is rotatable relative to the stator such that the rotor projections move in and out of fluid communication with the stator flow channels to create fluid pressure pulses in fluid flowing through the stator flow channels. At least one of the rotor projections and at least one of the stator projections has a standard outer diameter. At least one of the rotor projections and/or at least one of the stator projections has a reduced outer diameter. The reduced outer diameter rotor and/or stator projections provide bypass channels for flow of fluid and allow for generation of a pattern of different fluid pressure pulses.
