Abstract
For an integrated multi-technology interpretation study in the Gulf of Mexico aiming to increase imaging quality and geological reliability, 2D/3D gravity and magnetic modeling, inversion and joint visualization of seismic and additional constraining data is applied. In a combined interpretation approach existing depth models are updated, refined and improved regarding geometries and geophysical properties as velocity, density and susceptibility, with focus on salt features as main imaging problem zones. As a result of this study an improved salt geometry could be delivered for PSDM, optimizing the seismic imaging on the 2D profiles. Also areas of differing model conceptions in gravity/magnetic and seismic interpretation were identified and adjusted. Thus a more reliable regional structural concept was achieved.
