P05 Abstract SEISMIC SIGNATURES OF TWO ORTHOGONAL SETS OF VERTICAL MICROCORRUGATED FRACTURES R. F. FUCK 1 and I. TSVANKIN 2 1 Reservoir Characterization Project Colorado School of Mines Golden CO 80401-1887 USA 2 Center for Wave Phenomena Colorado School of Mines Golden CO 80401-1887 USA Conventional fracture-characterization techniques operate with the idealized model of penny-shaped (rotationally invariant) cracks and ignore the roughness (microcorrugation) of fracture surfaces. Here we develop analytic solutions based on the linear-slip theory to examine wave propagation through an effective triclinic medium that contains two microcorrugated vertical orthogonal fracture sets in isotropic background rock. The corrugation of
