Abstract
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.
