Description
This 4-day field trip in northwestern Sicily will provide the basics of carbonate reservoir characterisation on the field, by means of spectacular exposures, visits to quarries and seismic scale outcrops. The main aims are to describe and illustrate the peculiar geological and petrophysical control factors occurring in carbonate reservoirs.
The instructor will focus on the main sedimentological characteristics of different carbonate reservoirs (pore diagenesis, facies, primary structures, palaeontology, evolution and sequence stratigraphy) coupled with the role of fracturing (vertical and horizontal). Prediction criteria in fractures orientation will be explained, with limits and constraints. The course focuses on the seismic aspects of carbonate reservoirs and the correlation with the outcrops. The role of permeability and anisotropy in fluids within the reservoir and the relationship between boreholes and fractures will be covered using natural examples. A set of outcrops of shallow water carbonates affected by meso and macro volcano-dykes and atollo-type successions will show you some of the risks and critical factors occurring in reservoirs.
At the end of this course you will be able to describe carbonate reservoirs at different scales, starting with pore networks and rock textures, followed by sedimentary bodies and stratigraphic-structural macro-architectures.
These outcrops provide a natural laboratory to properly learn and experiment with methods for characterising and modelling carbonate reservoirs.
