Diffractor Imaging Using Cross-well Data for Mapping Reservoir Heterogeneities

Most of conventional imaging techniques are designed to locate the reflecting interfaces in the subsurface. But the scattering objects (diffractors), such as faults or salt inclusions, are also of interest for exploration. We have developed the reflection and diffraction imaging methodology for cross-well data. The methodology is based on weighted vector/noise Kirchhoff migration. We have applied these methodology to a multicomponent cross-well data set acquired in an onshore field. The obtained results illustrate the potential of cross-well diffractor imaging for advanced reservoir characterization.
