Abstract: A method for transferring data between a surface computer and a downhole assembly may include connecting the surface computer to a single data port in the downhole assembly, transferring data between the surface computer and a first while drilling tool through the data port, and transferring data between the surface computer and a second while drilling tool through the data port.

Abstract: A rotary coupler for transferring electrical power and data between members is presented wherein the coupler has a first member having an internal surface, a first inductor positioned on the internal surface, a second member and a second inductor carried on a portion of the second member and positioned internal of the first inductor, wherein one of the inductors rotates relative to the other inductor.

Abstract: A method for communicating signals between an instrument in a wellbore and a device at the Earth's surface using a wired drill pipe telemetry channel includes allocating signals generated by at least one instrument in the wellbore to a plurality of buffers. Each buffer represents data having a respective communication priority. Signals from each buffer are communicated to the wired drill pipe telemetry channel according to a predetermined priority procedure. The procedure allocates telemetry channel priority related to the communication priority.

Abstract: A system transmits a wireless power transmission from a bottom hole assembly of a drill string. The system has a downhole component having a wireless power transmitter adapted to wirelessly transmit at least one wireless power transmission and a wireless power receiver adapted to receive the at least one wireless power transmission.

Abstract: A connector connects auxiliary flow lines and electrical lines that extend through and terminate at or near opposing ends of two respective components of a downhole tool string. The connector comprises a body assembly for fluidly-connecting the auxiliary flow lines and electrically-connecting the electrical lines of the respective two components, and an assembly for adjusting the length of the body assembly. The two components are discrete modules of a unitary tool, or alternatively, are distinct tools. Additionally, the connector may include a mechanism for closing the auxiliary flow lines of one or both compartments upon disconnection of the fluid connection between the two components.

Abstract: A connector connects auxiliary flow lines—and, in some configurations, electrical lines—that extend through and terminate at or near opposing ends of two respective components of a downhole tool string. The connector comprises a body assembly for fluidly-connecting the auxiliary flow lines and electrically-connecting the electrical lines of the respective two components, and an assembly for adjusting the length of the body assembly. In particular embodiments, the two components are discrete modules of a unitary tool, or alternatively, are distinct tools. Additionally, the connector may include a mechanism for closing the auxiliary flow lines of one or both components upon disconnection of the fluid connection between the two components.
