Abstract: Systems, devices, and methods for evaluating an earth formation intersected by a borehole using signals produced at a plurality of borehole depths by an ultrasonic transducer in the borehole, the signals produced by the transducer including ringdown signals from the ultrasonic transducer and echo signals from a wall of the borehole from a plurality of azimuthal orientations. Methods include using peak amplitude values and arrival time values from the signals to construct a background modulation template corresponding to at least one depth; estimating, for each respective depth of the plurality of borehole depths, an azimuthally varying interference pattern predominantly resulting from a ringdown signal for each respective depth by mapping the modulation template to arrival time values corresponding to the respective depth; and subtracting, for each respective depth, the estimated varying interference pattern from the peak amplitude values corresponding to the respective depth to generate adjusted peak amplitudes.

Abstract: Methods, systems, and devices for downhole evaluation using a sensor assembly that includes a sensor plate, wherein a surface of the sensor plate forms a portion of an exterior surface of a downhole tool. Methods may include submerging the surface of the sensor plate in a downhole fluid in a borehole; activating the sensor assembly to generate a guided wave that propagates along the sensor plate, wherein propagation of the guided wave along the sensor plate is dependent upon a parameter of interest of the downhole fluid; and using information from the sensor assembly relating to the propagation of the guided wave along the sensor plate to estimate the parameter of interest. Methods may include isolating an opposing surface of the sensor plate from the downhole fluid. The guided wave may be an interface guided wave or may propagate in the plate between the surface and an opposing surface.

Abstract: An apparatus for imaging a borehole wall includes an array of acoustic transducers and a controller. The controller scans a section of the borehole wall with first acoustic beams that are transmitted by a series of sets of acoustic transducers in the array to produce adjacent first acoustic measurements that are spaced a first distance D1 apart along the borehole wall, each set having at least one transducer that is different from an adjacent set, (ii) steers a second acoustic beam along the section of the borehole wall using one set of acoustic transducers in the array to produce adjacent second acoustic measurements that are a second distance D2 apart along the borehole wall, and (iii) images the borehole wall using the first acoustic measurements and the second acoustic measurement to generate a borehole wall image, wherein at least one second acoustic measurement is between adjacent first acoustic measurements.

Abstract: Measurements made by a transducer assembly for downhole imaging are affected by reverberations between the transducer and the window on the outside of the assembly. The reverberations result in a stationary noise on the image. Hardware solutions to improve signal-to-noise ratio includes using a composite transducer, adjusting the distance between the transducer and the window. SNR can also be improved by processing techniques that include stacking, fitting a sinusoid to the reverberation, by envelope peak detection, and by applying a notch filter.
