    Abstract: The present disclosure relates to methods and apparatuses for estimating a parameter of interest of an earth formation. The method may include using an acoustic sensor azimuthally positioned relative to a monopole acoustic source to reduce at least one high- order mode due to the monopole acoustic source. The monopole acoustic source may include one or more acoustic elements. The method may include generating a monopole acoustic pulse. The apparatus may include at least one acoustic source element and at least one acoustic sensor disposed on a housing configured for conveyance in a borehole. The at least one acoustic sensor may be azimuthally positioned relative to the at least one acoustic source to reduce at least one high-order mode.

    Abstract: The present disclosure is related to apparatuses and methods measuring and processing a characteristic of subsurface earth formations penetrated by a borehole. More specifically this present disclosure relates to a method and apparatus for measuring and processing an acoustic characteristic such as formation shear wave velocity of subsurface sonic waves after these waves traverse earth formations adjoining a borehole or passing through a portion of the subsurface. The apparatus may include: a bottomhole assembly, a drill bit configured to generate an acoustic signal, at least two acoustic detectors, and a processor. The acoustic signal may include a specific multipole signal that may propagate through an earth formation along the borehole. The method may include use of the apparatus, including steps for estimating a shear velocity of the acoustic signal using signals from the at least two acoustic detectors.

    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.
