Methods and systems for taking acoustic measurements related to subterranean formations. The methods and systems provide extracting a portion of the acoustic measurements based on predetermined parameters for selecting reflected arrival waves in the acoustic measurements; generating time projection of the extracted acoustic measurements versus borehole depth; and generating an indication or imaging of acoustic reflectors in the formation based on the time projected acoustic measurements.

Methods and systems for processing acoustic waveform data

A method and apparatus for imaging subsurface fractures using an ST plane for quick looks and quality checks at the wellsite. Incident angles of impinging acoustic waves with respect to receivers are estimated from actual and apparent slowness, and the position of the fracture is estimated from the travel time and incident angle. The fracture can be imaged by plotting values from the ST plane onto the position of the fracture.
