    Abstract: Systems and methods for determining physical properties of a material in contact with an external surface of a casing disposed in a borehole including inducing, with a transducer, a first shear horizontal (SH) wave in the casing at a first SH order, measuring, with a sensor disposed on the casing, an attenuation of the first SH wave to generate a first measurement, inducing a second SH wave in the casing at a second SH order that is different from the first SH order, measuring an attenuation of the second SH wave to generate a second measurement, and extracting a physical properties of the material in contact with the external surface of the casing from the first and second measurements.

    Abstract: An apparatus for monitoring deployment of filtration media at least partially surrounding a tubular disposed in a borehole penetrating the earth includes a carrier configured to be conveyed through the tubular, a low-frequency acoustic wave source disposed on the carrier and configured to transmit acoustic waves in a frequency that is less than 3000 Hz into the tubular, and an acoustic wave receiver disposed on the carrier a distance from the low-frequency acoustic wave source and configured to receive acoustic waves transmitted by the low-frequency acoustic wave source. The apparatus also includes a controller configured to compare data characterizing the received acoustic waves to reference data characterizing acoustic waves with the filtration media not deployed.

    Abstract: Disclosed herein is a method of delineating a second wellbore from a first wellbore. The method includes, emitting acoustic waves from a tool in the first wellbore, receiving acoustic waves at the tool reflected from the second wellbore, and determining orientation and distance of at least a portion of the second wellbore relative to the tool.

    Abstract: An embodiment of a method of estimating characteristics of an earth formation includes: disposing an acoustic tool in a borehole in an earth formation, the acoustic tool including an acoustic multipole transmitter and at least one multipole acoustic receiver; transmitting acoustic signals into the borehole, the acoustic signals generating at least one acoustic body wave that radiates away from the borehole into a far-field formation region; measuring reflected signals including body waves reflected from reflective boundaries in the far-field formation region; identifying a reflective boundary in the formation and reflection attributes associated with the reflective boundary; and estimating at least one of a thickness, distance and a lateral extent of a hydrocarbon formation feature based on the reflected signals and the reflection attributes.

    Abstract: Disclosed is a method implemented by a processor for imaging a formation penetrated by a borehole. The method includes: obtaining acoustic data in a depth-time domain using an acoustic downhole tool disposed at a depth in the borehole, the acoustic downhole tool having an acoustic source and an acoustic receiver; transforming the acoustic data in the depth-time domain into a Radon domain using a Radon transform; filtering the acoustic data in the Radon domain to increase a signal of interest in the acoustic data in the Radon domain; determining a location of a point in the formation that reflected acoustic energy emitted from the acoustic source to the acoustic receiver, the location of the point being represented in the Radon domain; and inverting the location of the point represented in the Radon domain into a radius-depth domain to image the formation.
