Simultaneous Joint Inversion of Seismic and Gravity Data for Long Offset Pre-Stack Depth Migration in Northern Oman

Summary The problem of data-driven velocity model building for depth-imaging applications is approached from the point of view of simultaneous joint inversion of separate geophysical domains. For this purpose a general formulation of the joint inversion problem is provided. The method is then applied to a real (long offsets) seismic dataset from Omani thrust-belt where seismic travel-time residuals (first-break and Common Image Gather residuals) are jointly inverted with gravity data (in the form of Bouguer anomaly) for improving velocity model building and the corresponding depth-domain seismic image.
