Abstract
Within the scope of multi-technology interpretation projects in Mexico and the Gulf of Mexico, gravity, gravity gradient and magnetic data are jointly modelled and inverted. This iterative seismic and non-seismic interpretation process improves the geological depth model, focusing on salt features as main imaging problem zones. Analysing well logging data results in regionally valid, layer specific density-velocity relations which enable an independent gravity-based control of the seismic velocity model. This results in a final increase of seismic imaging quality.
