Shear‐wave birefringence: A new tool for evaluating fractured reservoirs

摘要: Propagation characteristics of shear waves make them particularly well suited to exploration for and definition fractured reservoirs. The Department Geophysics at Colorado School Mines conducted a three‐component P- S-wave seismic survey in order determine whether shear‐wave polarization splitting (birefringence) caused by fracture induced azimuthal anisotropy could be measured over naturally reservoir. Results indicate that surface recordings can used calculate observation provide information about the location, orientation, intensity subsurface fractures. Data obtained from this investigation measurement birefringence is potentially powerful tool predicting orientation permeability trends.
