The present paper investigates the oil migration and lineament distribution in fault zones within a sedimentary basin, showcasing the results from an integrated use of geochemical, and remote sensing data along the Fazenda Belém Fault Zone (FBFZ) in the Potiguar Basin, Brazilian Equatorial Margin. Lineaments were detected from a LiDAR digital elevation model data set using the quantitative method of morphology recognition based on horizontal and vertical curvature calculation and mapping. The polynomial regression-based spatial distribution of 20S/(20S + 20R) C29 steranes is successfully used in oils from offshore and onshore reservoirs of the Potiguar Basin, tracing field-scale oil migration direction. These multidisciplinary analyses revealed that the oil initially migrated from an offshore area along the NE-oriented fault zone, and then parts moved along the branches of this zone to finally reach the areas of the onshore reservoirs. In addition, NE-oriented lineaments enhanced the near-surface fluid circulation, while they commonly correspond to the topographic features and fault zones. Anisotropy tensors and slip- and dilation tendency calculated from the lineament map also indicate that the geometric complexity of the lineament pattern is influenced by present-day and partitioned stress fields in the Potiguar Basin. The integration of remote-sensing and geochemistry analyses at the FBFZ area proved to be effective in approaching the tectonic aspects of a fault zone in a petroleum basin, as well as in investigating the field-scale migration of oil along the fracture corridor in a fault zone.
