Method for Detecting, Locating and Characterizing Single and Multiple Fluid-Filled Fractures in Fractured Formations

Abstract: 

A method to analyze full waveform multiple (i.e., monopoles, dipoles, quadrupoles) acoustic measurements in a fluid-filled borehole, surrounded by a system of fractures oriented parallel to the axis of the borehole. The method uses new measurement attributes, herein referred to as dual flexure waves and leaky fracture mode.
