A theoretical foundation is developed for active seismic reconstruction of fractures endowed with spatially-varying interfacial condition (e.g. partially-closed fractures, hydraulic fractures). The proposed indicator functional carries a superior localization property with no significant sensitivity to the fracture's contact condition, measurement errors, and illumination frequency. This is accomplished through the paradigm of the F-factorization technique and the recently developed Generalized…

Differential tomography of micromechanical evolution in elastic materials of unknown micro/macrostructure
TLDR
The proposed differential indicators that specifically recover the 3D support of micromechanical evolution within a network of unknown scatterers are illustrated through a set of numerical experiments for spatiotemporal reconstruction of progressive damage zones featuring randomly distributed cracks and bubbles.
Asymptotic methods in inverse scattering for inhomogeneous media
In this thesis we study three different problems associated to the detection of two types of material defects: interfacial cracks and delaminations. In Chapter 2 we address the problem of interfacial

Characterizing the spatially heterogeneous fracture compliance through use of elastic waves has the potential to illuminate the hydraulic and mechanical properties along a fracture. We formulate the
Seismic characterization of fractured reservoirs by focusing Gaussian beams
ABSTRACTNaturally fractured reservoirs occur worldwide, and they account for the bulk of global oil production. The most important impact of fractures is their influence on fluid flow. To maximize
