Abstract: Methods, systems, devices, and products for performing well logging in a borehole intersecting an earth formation to obtain and transmit an acoustic reflection image of the formation. Methods include identifying a set of features in the acoustic reflection image substantially fitting a pattern, wherein the set of features corresponds to a portion of at least one reflecting structural interface of the formation; and using a representation of the pattern as the compressed representation of the acoustic reflection image. The features may be amplitude peaks in the acoustic reflection image, and the pattern may be a line segment therein that is obtained from the amplitude peaks. Identifying the set of features may include generating a binary image of the amplitude peaks.

Abstract: Methods, systems, devices, and products for formation evaluation. Methods include automatically characterizing an acoustic reflective boundary in the earth formation by: generating a plurality of multipole acoustic signals within the borehole; generating acoustic wave data at at least one acoustic receiver on the logging tool in response to a plurality of acoustic reflections of acoustic waves from a corresponding plurality of reflection points along the boundary responsive to the multipole acoustic signals; estimating from the acoustic wave data a location in the formation for each reflection point of the plurality of reflection points, which may include performing coherence processing on at least a portion of the acoustic wave data to generate a coherence map; and identifying acoustic reflections from the coherence map; and using the location in the formation for each reflection point to estimate at least one property of the acoustic reflective boundary.
