Abstract:
In this work we present results of a prospecting carried out with GPR and field observations, to determine the composition and geometrical characteristics of an eolic-fluvial interaction environment in Argentina. Three depositional subenvironments were defined and investigated: 1) eolian channel, 2) eolian interchannel and 3) muddy interchannel. In each of them, we acquired GPR data with antennas of different nominal frequencies in order to evaluate their resolutions and penetrations. From the GPR data sections, it was possible to identify numerous reflectors that were interpreted in terms of the field data. The applied methodology resulted very efficient for describing the complex deposits and provided relevant information for later constructing models for reservoir characterization. © 2019 24th European Meeting of Environmental and Engineering Geophysics.
