Patent ID: 10329856

Abstract:
A downhole communication system has a plurality of repeaters adapted to store segments of logging-while-tripping (LWT) data during tripping. The LWT data are transmitted to the repeaters during tripping and then read out from the repeaters at the surface. The segments and repeaters are read using one or more surface communication devices, such as a rack board, a stand verifier, a box cap, or a pin cap, each adapted to access and test segments of wired drill pipe each having one or more repeaters. The rack board includes an array of communication couplers that are each adapted to exchange signals with a pin coupler of a pipe segment. In turn, each communication coupler is connected with communication equipment adapted to process and display data stored in the one or more repeaters of the pipe segments during tripping. The stand verifier includes a communication coupler and is connected to communication equipment adapted to (1) verify the functionality of communication circuitry of the pipe segment before run-in and/or after trip-out, and/or (2) download after trip-out logging-while-tripping data stored in the one or more repeaters of the pipe segment during tripping, and/or (3) download parameters stored in the one or more repeaters of the pipe segment.
