Abstract

Currently, hydrocarbon reservoir modeling is the main tool used in oilfield management, from predicting its performance, planning and location of wells, to improving its recovery. However, data obtained in subsurface areas, such as well data and reflection seismic data, are not sufficient to infer the internal features of reservoirs that may contain important heterogeneities at various scales, such as body geometries and their connectivity, facies that make up the architectural elements and diagenetic features (of microscopic scales) that interfere in different ways in the flow. The use of the LIDAR technique allows the generation of a digital model of the surfaces with high quality of visualization, so that it is sufficient for the geological analysis and interpretation, allowing to interpret areas of the outcrop that are inaccessible with the same visual quality of areas where a geologist could access during a field work, making it possible to establish precise measurements, such as height, extension, thickness of sedimentary strata, orientation of planes. The use of the Laser Scanner for data analysis is due to a variety of advantages over traditional methods of analysis, such as rapid data capture, in addition to computational mobility that allows interpretation to be more coherent and accurate. It is possible to check the continuity of surfaces that are being interpreted in different faces of the same outcrop or of different outcrops in the same region. This is an advantage that the conventional field work does not allow because of the limitation of the visual field that the human being has in relation to the distance of the object of study or the distances between different points of the study region.
