Abstract

Summary

The result of the proposed workflow provides new insights into the seismic imaging of fractured basement reservoirs. By utilizing elastic full-waveform inversion and common image point tomography, and by integrating both the diffraction and reflection components of the wavefields, this workflow produces superior seismic images compared to vintage processing. The findings of this study are particularly pertinent for regions characterized by fractured basement formations, where precise imaging of complex subsurface structures is vital for minimizing exploration risks and optimizing hydrocarbon extraction.
