This course provides a practical, integrated approach to characterising, classifying, analysing and modelling natural fractures. It uses lectures, modelling software and field examples to deliver an understanding of: geomechanics; the building and use of simple conceptual and more complex finite difference models; and the impact of fractures on well and reservoir productivity and recovery. The course combines field sessions in Somerset looking at world-class fault and joint systems along with classroom sessions assessing the Quantock Field case study that contains different host lithologies and structures that require participants to perform data analysis, fracture model design and creation of a modelling plan.

Participants will learn to:

1. Characterise the presence or influence of fractures from a multitude of data sources (open-hole logs, core, image logs, mud losses, PLT’s, well tests, and production performance).
2. Construct simple conceptual models of fracture origins, types, and distributions for use as input to reservoir modeling.
3. Plan preliminary proposals for selecting the optimal modeling process for specific modeling objectives.
4. Develop simplified implicit fracture property models (i.e. fracture porosity, fracture permeability, and sigma) in geocellular modeling packages.
5. Integrate simplified fracture properties into a finite difference simulator.
6. Evaluate fracture/matrix fluid exchange mechanisms of imbibition and gravity drainage.
7. Instigate and run a finite difference simulator in dual porosity/dual permeability mode.

This course is aimed at subsurface professionals working in Oil & Gas, CCS, Gas Storage and Geothermal to provide a basis for understanding and modelling fault and fracture systems and their influence on fluid flow in reservoirs and caprock systems.
