Learning objectives
At the end of the course, the student will be able to:
- be able to evaluate the quality of the geological information available on a study area;
- be able to work in a team for addressing complex geological problems;
- produce geological models of buried structures and related balanced cross-sections;
- perform quantitative structural analysis of brittle deformational features associated with folds and fault systems at the reservoir scale;
- perform statistical analysis of field data to obtain empirical scaling laws;
- develop conceptual models of fluid flow patterns in reservoir-scale structures.
Prerequisites
Previously achieved Structural Geology exam
Course unit content
Workflow of fracture pattern predictions in reservoirs including the construction of balanced cross-section and the study of natural analogues exposed at the surface to obtain empirical laws suitable to be used to populate reservoir models.
Full programme
1 – Crustal-scale geological cross-sections: purposes, boundary geological information and techniques for the geometric construction.
2 – Cross-section balancing techniques and application to the Palazzuolo Anticline, Northern Apennines.
3 – Predicting fracture patterns in buried geological structures: conceptual templates, kinematic models, numerical models and natural analogues.
4 – Techniques for the quantification of fracture abundance in natural analogues: linear and circular scan lines, circular scan windows, topology of fracture sets.
5 – Probability distribution functions of fracture spacing data and indexes for quantifying fracture abundance: P10, FSR, H/S FSI, S/T, JSR, Cv, JPI, JRI.
6 – One week of field work in the Palazzuolo anticline: quantification of fracture abundance in this natural analogue and discussion of the implication of the results for the buried structures predicted in the previously produced balanced cross-section.
Bibliography
Scientific papers on specific subjects and teaching material (PPT slides).
The slides of the lectures will be uploaded on Elly every week. To download the slides, the registration to the online course is required. The slides are part of the teaching material but they do not replace the recommended books. Students are invited to periodically check the teaching material available in Elly.
Teaching methods
Lectures and heuristic-Socratic lectures, case studies, cooperative learning, field activity.
Assessment methods and criteria
The final evaluation results from:
1 – results of the construction of the balanced geological cross-section of the Palazzuolo Anticline;
2 - written report on the results of the field activity and discussion of the implications for the prediction of fracture patterns in the buried structures of the balanced geological cross-section;
3 – oral exam.
Other information
The field work week will be spent in the Santerno river valley, south of Imola, Italy.
