Abstract
Summary
This paper shows the preliminary results of GPR and ER profiles on asphaltic sandstones. The study area is located in the municipality of Anhembi, situated on the eastern border of the Paraná basin, central-eastern region of the São Paulo state, Brazil. The region has been the subject of studies by Petrobras (Brazilian Oil Exploration Company) due to the presence of cumulative bitumen in sandstones. The results of ER show zones of high conductivity that match with the absences of reflections in GPR profiles. Although preliminary, the results suggest the presence of bacterial action, featuring a biodegradation problem. Despite this, detailed studies are in progress to test the biodegradation hypothesis.
