Abstract (en)

[origin: US5592381A] A device for processing and interpreting drilling data is mounted at the lower end of a drill-pipe string located in a drilling well and provided with a drill bit and, measuring assembly. The device is arranged to transmit data from the bottom to the surface, but transmits only abbreviated messages to the surface after interpreting the measurements made by the measuring assembly. A method for implementing the device while transmitting data from the bottom of a drilling well to the surface in the form of abbreviated messages after interpreting the measurements made by the measuring assembly.
