02-04 d Applied Biostratigraphy

Biostratigraphy

• Microfossil evolution through the Stratigraphical Column
• Building stratigraphical range charts
• First downhole occurrence, last downhole occurrence, fossil assemblages
• Numerical methods, abundance increases and maxima
• Index fossils
• Stratigraphical type sections and the relation between Biostratigraphy and Chronostratigraphy

Biostratigraphical Correlations and Correlation Techniques

• Pitfalls using biostratigraphical data, downhole caving, reworking, contamination
• Definition of biozones
• Integration of sedimentological and petrographical data
• The integration of geochemical information
• Identification of unconformities / hiatus in the sequences

Biostratigraphy, Paleoenvironments and Sequence Stratigraphy

• Using Micropalaeontology for palaeoenvironmental interpretation
• Marine microfossils vs. non-marine microfossils
• Preservation of microfossil groups and different lithologies
• Definition of water depth from the different fossil groups
• The identification of sequence boundaries using biostratigraphical Data
• Using biostratigraphical data to identify condensed sequences and maximum flooding surfaces
• Using biostratigraphical data to identify low stand System and high stand system tracts

Play Definition using Play Based Exploration Techniques

• Hydrocarbon Play definition
• Integrated Biostratigraphy and its use in Play based exploration techniques
• The deltaic to marine Cretaceous Alagamar Play in Potiguar Basin, Equatorial Marginal of Brazil
• The Cenozoic deep-water turbidites and associated salt play, Lower Congo Basin, Angola
• The Early Silurian Hot shales of the Arabian plate, source rock characterization
