Application of AVAZ and VVAZ Study to Predict Fractured Reservoir Using Full-Azimuth Seismic Data - A Case Study in a Field of Cauvery Basin, India

Natural and induced fractures play a vital role in determining hydrocarbon producibility in basement exploration. An accurate understanding of fracture networks is critical for optimizing development in naturally fractured reservoirs, since the intensity and orientation of fractures significantly affect fluid flow in the reservoir rocks. Assorted techniques are available to characterize these fractures.

This work proposes a novel approach — azimuth-dependent analysis — for sweet spot identification in the basement.
