Interpretação Sísmica e Avaliação de Oportunidades Exploratórias na Área do Pré-Sal, Norte da Bacia de Santos

This study presents an exploratory workflow performed in a dataset acquired in northern Santos basin, near the Oliva field, southeast of Brazil. The workflow consists of geoscience activities, comprehending mainly the fields of Geology, Geophysics, Petrophysics and Geostatistics applied to the available dataset (2D seismic lines in Strike and Dip directions, 3D seismic volume and data obtained from eight wells drilled around the area, including stratigraphic markers and well-logs). As results, two opportunities were defined: two leads in the Pre-Salt Play, which were named as, Açaí and Guaraná, respectively. The volumetric analysis establishes a VOIP of 427 MMbbl (P50) for Açaí and 453 MMbbl (P50) for Guaraná structure. Comparisons between the volumetric data obtained during this research and those forecasted by ANP (National Petroleum Agency) and PETROBRAS concerning the pre-salt reservoirs came to assist and enhance the reliability of the present study.
