Abstract: Apparatus, systems, and methods for investigating a subsurface volume of interest from a borehole. Apparatus comprise an enclosure configured for conveyance along the borehole; an acoustic source in the enclosure configured to generate acoustic signals; a lens assembly disposed in the enclosure and next to the acoustic source, the lens assembly being formed of a plurality of cells, each cell formed as a column oriented transverse to a direction of travel of the acoustical signals. Each cell comprises a plurality of cell segments with each cell segment of the plurality comprising at least one arcuate wall and at least one radial finger, and wherein the cell segments are oriented in alignment with a rhodonea conformal mapping geometry in a plane transverse to the column to cause acoustic waves to travel at a different speed in each of three orthogonal directions.

Abstract: An apparatus for investigating a subsurface volume may include an acoustic transducer disposed in an enclosure and generating acoustical signals, an electronics assembly disposed in the enclosure and controlling the acoustic transducer, and a lens assembly. The lens assembly may be disposed in the enclosure and next to the acoustic transducer. The lens assembly may be formed of a plurality of cells. Each cell may be formed as a column oriented transverse to a direction of travel of the acoustical signals. Each cell may have a hub, a plurality of spokes radiating from the hub, and a plurality of fingers circumferentially distributed around the hub. The hub, spokes, and fingers may be oriented to cause the acoustic waves to travel at a different speed in each of three orthogonal directions. A related method uses the apparatus in a wellbore.

Abstract: A system and method of estimating properties of a wellbore fluid that directs the fluid through a cavity, and generates acoustic waves in the fluid while in the cavity. The acoustic waves are generated by oscillating an electroactive material over a range of frequencies. An electrical admittance spectra of the electroactive material is measured over the range of frequencies; where the electrical admittance spectra includes the magnitude, real, and imaginary components. Differences between the maximum values for each component and a vacuum electrical spectra are calculated, the differences are substituted into estimator equations to estimate the fluid properties. Electrical admittance spectra of the electroactive material was simulated for a series of known fluids flowing through the cavity, and a multi-regression statistical analysis was then used to derive the estimator equations.

Abstract: An acoustic energy source that amplifies the stroke of electrically reactive elements having a body with an elastomer filled first cavity, a highly incompressible fluid filling a second cavity, and bores intersecting the second cavity that extend radially outward from second cavity. Quill assemblies in the bores each include an electrically reactive element and a tip projecting radially into the second cavity. A dynamic yoke having a lower portion projecting into the second cavity, and a pressure disk projects into the first cavity. A diaphragm on the body and on a side of the dynamic yoke opposite its lower portion. A fluid forms a film between the dynamic yoke, static yoke and quill tips. Applying alternating electricity reciprocates the tips into and out of the second cavity; reciprocates the dynamic yoke and diaphragm to generate the acoustic energy.
