Fracture mapping using seismic amplitude variation with offset and azimuth analysis at the Weyburn CO2 storage site
Cap rock integrity is an essential characteristic of any reservoir to be used for long-term CO 2 storage. Seismic AVOA (amplitude variation with offset and azimuth) techniques have been applied to map HTI anisotropy near the cap rock of the Weyburn field in southeast Saskatchewan, Canada, with the purpose of identifying potential fracture zones that may compromise seal integrity. This analysis, su
