Seismic fluid identification plays an important role in reservoir exploration and development. Natural vertical fractures are common carbonate rocks, it is essential to consider fracture-induced anisotropy the of fractured reservoirs. We have developed a novel Bayesian elastic impedance variation with angle azimuth (EIVAZ) inversion approach for directly estimating fracture indicator (FFI), whi...

Joint Inversion of Fracture Model Properties for CO2 Storage Monitoring or Oil Recovery History Matching — For oil recovery or CO2 storage, “reservoirs” are commonly used to designate geological structures where oil can be found or CO2 can be stored. All reservoirs present a heterogeneity in terms of rock type and properties (such as porosity and permeability). In addition, some of these reserv...

Seismic methods play an important role in the development of tight fractured reservoirs with substantial spatial variability of fracture density. Here, we apply a comprehensive processing sequence designed for layered azimuthally anisotropic media to wide-azimuth P-wave data acquired over a fractured gas sand formation in the Rulison field, Colorado. The main processing steps include nonhyperbo...

Field, laboratory, and modeling studies of fractured rock have generated great interest from both fundamental and applied perspectives. Many practical applications of these studies are crucial for the exploitation of petroleum and geothermal reservoirs, the safe environmental management of groundwater, the isolation of radioactive waste in under­ ground repositories, cleanup technologies for ot...
