Ichnofacies analysis, which is based on animal-sediment interaction and related assemblages of trace fossils, provides critical information about depositional environments and also stratigraphic discontinuities. Ichnofacies analysis is well integrated with paleontology, stratigraphy, and sedimentology and is very useful for high-resolution paleoenvironmental reconstruction. One of the advantages of applying ichnofacies analysis lies in its prospective integration with sedimentological facies analysis (lithofacies). Qualiterra offers high-resolution ichnofacies analysis and combines it with related sedimentological core analysis in order to provide a detailed reservoir characterization of marine and marginal marine environments.
