Course content
As part of a more extensive course on Fractured Reservoirs, I have developed the geophysical part called "Seismic Fracture Detection". It discusses the seismic acquisition requirements for multi-azimuth analysis using NMO velocity anisotropy to determine the fracture orientation of vertical fracture systems and Amplitude versus Angle of Incidence (AVA) for improved resolution and determination of fracture density. The use of P-wave, PS-wave (Converted-wave) and S-wave data are discussed and used in AVA exercises. The program, which could be given Face-to-Face or Virtual, is as follows
