Latest Patents

Bernard Vivet holds 2 patents that showcase his expertise in acoustic well logging. His latest patents include:

1. **Acoustic well logging with threshold adjustment** - This invention provides methods and apparatus for investigating earth formations traversed by a borehole. Acoustic waves are transmitted from different points in the borehole and received at other points, generating a reception signal representative of the received acoustic waves. The time interval between the transmission of measurement waves and the moment the reception signal exceeds a given detection threshold is measured as a function of depth. The detection threshold is adjusted during each measurement sequence based on the amplitude of the noise received during the preceding listening interval.

2. **Apparatus for use in investigating earth formations** - This invention features a substantially rigid member with interruptions in its longitudinal continuity, creating tortuous paths for the passage of acoustic energy. A plurality of masses are periodically spaced along the interior of the member, mechanically integral with opposite sides at locations chosen to enable cooperation as a mechanical filter. This structure provides excellent acoustic delay and attenuation characteristics, along with good mechanical properties.
