Abstract

Recent observations show that the differential amplitudes between the faster and slower split shear-waves in reflection surveys contain information about lateral variations of crack density in cracked reservoirs (Mueller 1991 ; Li, Crampin and Mueller 1992). However, the variation of amplitude with crack geometry when the crack strike changes with depth has not been investigated previously. In this paper, we derive expressions for reflection and transmission coefficients of plane split shear-waves at vertical incidence at an interface separating two cracked (anisotropic) media with different crack strikes. We also examine the effects on these coefficients of variation in crack strike and crack density .
