Studying geological fractures from seismic data not only requires performing forward modeling and backward inversion, but also required an understanding of the rock mechanisms and some geophysical hypotheses related to fractures. In this chapter, many indispensable fundamental concepts are reviewed that are associated with fracture formations, fracture types, fracture parameters, fracture detections, fracture equivalent hypotheses (effective fractures), fractured media composition, and decomposition and fracture interface boundary conditions especially, rock deformations, Anderson’s principal stresses classification (Trans Edinb Geol Soc 8: 387–402, 1905), petrophysics technologies, linear slip theory (Schoenberg in J Acoust Soc Am 68: 1516–1521, 1980), Schoenberg and Muir calculus theory (Geophysics 54: 581–589, 1989), welded contact boundary conditions, and nonwelded contact boundary conditions are explored and integrated to form a substantial body of material supporting the geological fractured media forward modeling in Chap. 3 and seismic inversion in Chap. 4 of this book. |
