Abstract:
This paper presents a study of the gravitational geopotential of the Brazilian Pre-Salt region based on the gravimetric data of the EGM 2008 and Topex models. From these data, maps of gravity anomaly, gravity disturbance, geoid height and bathymetric maps were constructed. The maps allowed us to evaluate the region's water depth and to locate the Pre-Salt region and its main producing fields in a strong and negative anomaly of gravity, both in the Topex model and in the EGM 2008 model. It was demonstrated that the Santos Basin presented greater disturbance and anomaly of gravity than the Campos Basin.
