The Santos Basin is considered the main potencial basin of of Brazil with several proved oil fields, mainly the pre-salt. With mostly of main fields locates at ultradeep waters, the present work turns it´s approach to the proximals fields inserts in the post-salt sequencies to identify potential. The project used data available from Agência Nacional de Petróleo (ANP), being between those, 2D sismic lines, 3D sismic cube and well data drilling in the área. The development of this work focused in the drif sequence, at the central portion of the basin. The research metodology began with a sismic wich use well-tie and domain coversion deep-velocity. Through these, was posible to identify the sismic horizons and using sismofacies and geobody technique, sand turbites were interpretated as reservoir of the oil system of the presente lead. Then, using the wells, petrophysical calculations were make from the well 1-BRSA-498-SPS, generating values of total porosity, water and oil saturation and Net-to-Gross of the Ilha Bela Member sands. In the conclusion of this work, was estimated the presente oil volumetric, with values of 14616,4 MM STB to oil in place and to volume of recoverable oil a value of 3650,5 MM STB. To achieve this results, were insert calculated parameters of the rock, fluid and thick and área of the reservoir, in the Monte Carlo simulation.
