oa Reservoir Analogues Characterization by Means of GPR

The study of hydrocarbon reservoir analogues is increasing important because often there is a gap between ultra high-resolution data obtained by well logs and the information extracted from reflection seismic data. Ground Penetrating Radar (GPR) can be applied to extend the knowledge attainable from outcrops and boreholes obtaining an improved stratigraphic, tectonic, structural, geomechanical and petrophysical characterization of rock masses that can be considered analogue to hydrocarbon reservoirs. The primary objective of this work is to provide examples of GPR imaging and rock characterization helpful during exploration, exploitation and modelling of hydrocarbon reservoirs. We assess the GPR capability to identify rock layers related to sedimentary processes and features and to karstic/dissolution phenomena or tectonic processes, which can be often associated with higher porosity and permeability zones. Integrated velocity, attenuation and attribute analyses are discussed and validated with outcrops and rock samples data.
