Use of ground-penetrating radar for 3-D sedimentological characterization of clastic reservoir analogs

Clastic reservoir analogs based on 2-D outcrop studies provide valuable definitions of geometric and petrophysical heterogeneities at interwell scales. Integration of 3-D ground-penetrating radar (GPR) surveys with sedimentological and stratigraphic data provides information on the internal heterogeneities of sedimentary sequences at scales that allow dissection of the 3-D anatomy of elastic depositional systems. Two 3-D GPR data volumes were acquired in the Ferron sandstone of east-central Utah, The data show prominent lenticular features, a variety of lithologies, and structural elements such as channels and shale drapes that match well with those seen at the same stratigraphic levels in adjacent cliff faces.
