  • Downhole acoustic mapping
    Patent number: 10364664
    Abstract: A downhole tool for operation within a wellbore and including a transmitter array and first and second receiver arrays. The transmitter array includes a plurality of transmitters azimuthally distributed around a longitudinal axis of the downhole tool at a first axial location of the downhole tool. The first receiver array includes a plurality of first receivers azimuthally distributed around the longitudinal axis at a second axial location axially offset from the first axial location. The second receiver array includes a plurality of second receivers azimuthally distributed around the longitudinal axis at a third axial location axially offset from the first and second axial locations.
    Type: Grant

  • Methods and systems for acoustically monitoring formations
    Patent number: 8401796
    Abstract: Methods and systems for acoustically determining reservoir parameters of subterranean formations. A tool comprising a plurality of acoustic sources and configured for acoustic measurements is deployed within a wellhole. Acquired acoustic data are processed and utilized for deriving key parameters for the formations. The plurality of acoustic sources include a plurality of hammer sources, where at least one of the hammer sources includes an actuator that is adapted to strike a surface to generate acoustic energy.
