  • Patent number: 11725462
    Abstract: Electrical wet connection (EWC) with multiple power and communication lines for connecting Logging While Drilling tools (LWD) and/or Measurement While Drilling tools (MWD) is described. The contacts between the modules may be made by, for example, using pressure bulkheads to ensure protection of the tools if the pressure protection is reduced or lost. The contacts may be locked together in a convenient manner to eliminate downhole vibrations and/or shocks. The may make the signal transmission quality approaching, as good as, or even better than wireline tools. The connection may be sealed from the well muds under high pressure and this protection may be enhanced such as by doubling or even tripling for extreme reliability in difficult environments. The designs described herein may advantageously allow for a large amount in collar lengths to be compensated and/or provide two degrees of freedom-rotational and/or may be longitudinal for ready connection on the well site.
