Basement Delimitation of the Taubaté Basin

The aim of this study is to define the basement map of the Taubaté Basin applying geostatistics to seismic, gravimetricand deep wells data. The study consisted of the interpretation of eleven seismic sections obtained in the central andnortheastern portions of the basin. The altitude of the basement and the distribution of faults was determined based onthese sections. New information was obtained from 79 wells located mainly in the regions of S o José dos Campos andJacareí. The method of kriging with an external drift was applied, using seismic and well data as the main variables andthe gravimetric map as the secondary variable. The basement contour map obtained has a strong correlation with the mainfaults. It was possible to obtain a better resolution in the region of S o José dos Campos and in the northeast area, wherethe vast majority of wells are located.
