Simultaneous inversion of velocity and angle-dependent reflectivity

We introduce an innovative technique for simultaneous inversion of velocity and angle-dependent reflectivity. The key aspect of our method lies in extracting angle information from the solution of the vector-reflectivity-based wave equation, which is a crucial step in the process. The incorporation of pre-stack angle gathers significantly enhances our understanding of subsurface and reservoir properties. The outcomes of our approach encompass the velocity model, reflectivity image, and pre-stack angle gathers, along with the derived relative density and impedance. These results provide valuable insights for conducting reliable amplitude versus angle (AVA) analysis and quantitative interpretation (QI).
