Abstract
The offshore East margin basins, especially Campos, Santos and Espírito Santo, are the main oil producers in siliciclastics reservoirs in Brazil. However, in recent times large volumes of light oil in carbonate reservoirs in the Aptian presalt section in Santos (BM-S-11, Tupi prospect) have also called the attention of the oil industry due to its potential hydrocarbon content. To the geophysical community, imaging this kind of reservoir represents a new exploration frontier in its characterization and its seismic signature. The main challenge here is the<br>imaging under salt followed by the mapping of amplitude anomalies (e.g., AVO) related to carbonate reservoirs, which are extremely anisotropic in nature. This paper then presents the results of a simple modeling of a representative offshore presalt prospect considering its main geological characteristics.
