... ABSTRACT Current forward modeling techniques within inversions make use of the analytic solution for the gravity field and may face limitations when dealing with large scale problems and complex geometries. By using the finite element method, we derive both the forward and inverse problems...

... in the western GOM, and its base is rarely imaged in seismic at all. As rock salt has low density, the massive salt bodies create density contrasts with the surrounding sediments, which are the sources for anomalies in gravity fields. Thus, gravity data may be used as an independent tool to (1) test the existing...
