Investigation of fractured carbonate reservoirs by applying shear-wave splitting concept

In this study, fracture orientations in carbonate reservoirs were determined using a multicomponent velocity analysis based on shear wave splitting. The is the estimated velocities of large seismic events with different polarizations. fractured zone dominant orientation, weak amplitude split events, including noise, result waves that are polarized toward symmetry and anisotropy axes propagate common fast slow velocity, respectively. Thus, stack should show high coherency anomalies directions parallel orthogonal to strike. Furthermore, because applied locally at specific depth range, it less susceptible effects overburden noise. from four oilfields compared those interpreted fullbore microimager core data. Fractures two offshore strike NNE-SSW NW-SE, which related Zagros stress. onshore reservoir strikes NE-SW, while deeper fractures aligned N-S direction. findings study promising, particularly for especially located Abu Dhabi, characterized by heterogeneity complex network tectonic history. order obtain geometrical parameters scale, recommended implement adapted after acquiring three component zero-offset vertical profiling.
