Event Details

Course overview

This 4 day course in northwestern Sicily will provide the basics of carbonate reservoir characterization on the field, by means of spectacular exposures, and 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 reservoir (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 constrains. The course focuses on the seismic aspects of carbonate reservoir and the correlation with the outcrops. Role of permeability and anisotropy in fluids within the reservoir and relationship between boreholes and fractures will be cover 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 able to describe carbonate reservoir at different scales, starting from the pore networks and rock textures, to the sedimentary bodies and stratigraphic-structural macro-architectures. A robust part on characterization of fractured reservoir with practical exercises is scheduled. These outcrops provide therefore a natural laboratory to learn and experiment methods for characterizing and modelling properly carbonate reservoirs.

How we build your confidence
Clear and impressive field stops allow a visualisation of the different facies typical of Carbonate reservoir.
Graphic material on site, correlation with seismic and well dataset will help you to understand the geological control factors typical of reservoir modeling.
Practical exercises on geometries, fractures and heterogeneities of the reservoir will be conducted in quarries where a multiple exposure and variable geometries of cliffs permit a 3D visualization of critical surfaces.

The course is designed for

This course is suitable for geologists and geoscientists in general with some years of experience, that want to broaden and deepen their knowledge on carbonate reservoir (properties and control factors on modeling). It assumes basic knowledge in geoscience. It’s designed for reservoir engineers and explorationists wishing to improve their geological knowledge.

Course objectives

By the end of the course you will feel more confident in your understanding of geological key elements in characterization of carbonate reservoir. You will improve the capability to analyze and to assess properly the different control factors influencing a fractured reservoir, starting from petrophysical datasets and exporting to the large-scale reservoir.
