Abstract

In this work a potential field analysis (gravimetry and magnetism) of the salt structures interpreted in the offshore of the Asturias Basin. For this purpose, 2D processing of the anomaly maps and three models in 2+3/4D GRAV/MAG have been carried out with the data of a 3D seismic cube acquired by Repsol in 2008. The quantitative analysis of the maps and modeling has allowed the structure of the basement and salt structures until adjusting the GRAV/MAG signal. These modifi- cations are significant below the levels of evaporites, highlighting the need to introduce less salt, and a new geometry of the basement top.
