  • Patent number: 10168442
    Abstract: Systems and methods for differential energy analysis of dipole acoustic signals to facilitate identification of geological or borehole characteristics are provided. An acoustic downhole tool may be placed into a borehole in a geological formation. A dipole acoustic signal may be emitted using one or more acoustic transmitters of the downhole tool, and the dipole acoustic signal may be measured using one or more acoustic receivers of the downhole tool. Using a processor, a dipole differential energy of the dipole acoustic signal (as measured by two of the one or more acoustic receivers or as emitted by two of the one or more acoustic transmitters, or both) may be computed. The processor may provide an indication of the dipole differential energy to facilitate identification of characteristics of the geological formation or the borehole, or both.
    Type: Grant

  • Patent number: 8731837
    Abstract: A system and a method for associating measurements from a wellbore with times and depths is provided. Tools located in a wellbore obtain the measurements and provide time data used to determine the times. The tools and a surface clock may be synchronized. The times may be used to associate the measurements with corresponding depths of the wellbore.
