Magnetometria aplicada à Bacia Barinas-Apure

Abstract

ln this work we present a study of the Barinas-Apure bay geology in which its most important characteristics are evidenced by a theoretical study about the magnetic method applied to geophysics and a case study about the applied method. These two studies were directed towards the petroliferous prospection in the Barinas-Apure bay. The objective of our case study was to connect the studied geology to the magnetic method applied to the Barinas-Apure bay and, thereby, verify the method efficiency in petroleum prospection at the Andeans bays. Based on this, one could observe the magnetic method efficiency in recognize and detail lineaments of the basements, as well in interpret the main structures: the graben of San Fernando and the low structural graben. Hence, we could select zones which have their exploration justified by seismic methods. Beyond this, the possibility of different magnetic methods that estimate the distribution of crude oil in zones of exploration was verified.
