Title: DATA-DRIVEN FOCUSED INVERSIONS
Abstract:
DATA-DRIVEN FOCUSED INVERSIONS A method of processing geophysical data acquired from a subsurface region is disclosed. The method includes receiving geophysical data acquired from a subsurface region, determining data points which have high sensitivity to an anomaly, performing an inversion based on said data points, wherein during inversion focusing towards the anomaly is achieved by increasing the weight of said data points, and determining at least one model of the distribution of a physical property in the subsurface region.
