Abstract

The reconstruction of meander belts was approached by detailed
geological mapping, the interpretation of exposed sandstone bodies and the
application of sedimentological concepts. The single reconstructed meander belts
were integrated, considering stratigraphic position and thickness in a threedimensional
model of the depositional architecture. Some useful reservoir
parameters, such as volume of meander loops, areas of interconnection and fluid
flow barriers, are calculated from the obtained model. Sandstone porosity is mainly
of primary origin and mechanical compaction is the most iotense diagenetic feature.
Models of estimated permeability evolution in the point bar sequences have been
developed. Gamma ray readiogs from different lithologies were obtained and
grouped accordiog to their palaeoenvitonmental classification. The results are
comparable to well logs and aid subenvitonmental characterization of continental
deposits.
