Short hop telemetry system and method
First Claim
1. A method for communicating information axially along a drill string, comprising the step of conducting an axial electrical signal embodying the information between a first axial position in the drill string and a second axial position in the drill string through an axial conducting loop formed by the drill string, which axial conducting loop extends between the first axial position and the second axial position, wherein the drill string between the first axial position and the second axial position comprises an outer axial conductor and an inner axial conductor rotationally supported within the outer axial conductor and wherein the axial conducting loop is comprised of the inner axial conductor and the outer axial conductor.

Abstract
The invention relates to a data transmission or telemetry system and a method for communicating information axially along a drill string. The method includes the step of conducting an axial electrical signal embodying the information between a first axial position in the drill string and a second axial position in the drill string through an axial conducting loop formed by the drill string, which axial conducting loop extends between the first and second axial positions. The system includes the axial conducting loop for conducting the axial electrical signal embodying the information between the first and second axial positions and a transmitter for transmitting the information to the axial conducting loop. The system further preferably includes a receiver for receiving the information from the axial conducting loop. Finally, the portion of the drill string forming the axial conducting loop is preferably comprised of a downhole motor drilling assembly.
