Estudo de caso do método Sea Bed Logging (SBL) e da Geologia da Bacia de Santos

Abstract

The technique called sea bed logging (SBL) is a geophysical eletromagnetic method. Based on the great electric resistivity contrast between the petroleum bearing reservoirs and the other water bearing rocks, it is possible to directly identify hidrocarbons in subsurface. ln this work, we show an application of SBL and a study of Santos basin·s geology. First, we discuss the main characteristics of the basin: the stratigraphy, structural geology, historical geology and petroleum geology. Next, the principies of the eletromagnetic technique are shown. Finally, we describe the results of a SBL aquisition over the Troll gas field, at North Sea, as a possible case in Santos basin, recognized as a good potential place for gas production. The SBL proved that it is an efficient method for petroleum exploration.
