3-D Modeling of Reflection Coefficients at Thin Fluid Layers Representing a Hydraulic Fracture

Angle-dependent reflection coeffients at thin fluid layers are derived from 3-D synthetic data, deploying an explsion source and a double couple mechanism,and are compared to the analytical solution. The results are in a good agreement and support the idea that microseismic events can be reflected at hydraulic fractures with a high reflection coefficient. Examples from data recording microseimic events that will serve for further investigation with respect to reflection coefficients are shown.
