Training objectives
- The aim of this course is to describe some aspects of hydrocarbon formation, migration and definition of a petroleum system. Emphasis will be given to the multidisciplinary approach inside the geosciences and integration of geoscience and engineering. The goal of the course is make the student able to recognize the main elements composing a petroleum system.
Basic knowledge acquired by the students include:
The role of sedimentary rocks in the developing and storage the hydrocarbons
Improvement of the microscopic knowledge of sedimentary rocks;
The main abilities acquired by the students include:
recognition of the main elements composing a Petroleum System;
field evaluation of naftogenic properties of a source rocks;
microscopic identification and evaluation of primary and secondary porosity in the reservoirs Prerequisites
- Knowledge of the basics of geology of sedimentary rocks. In more detail: depositional and diagenetic processes acting on sediments and sedimentary rocks; sedimentary rocks petrography, and basics of stratigraphy and tectonics
Course programme
- 1.Introduction: sedimentary basins and oil search (4h).
2. Nature and classification of hydrocarbons. Composition and source of organic matter contained in sediments; kerogen classification and processes of source rocks formation (10h).
3. Generation and migration of hydrocarbons , thermal evolution of kerogen and hydrocarbons generation, primary migration. Thermal evolution of organic matter. Quantitative study of sedimentary basins dynamic: burial case histories and modeling of hydrocarbons generation. Source rocks and thermal history of sedimentary basins (14h).
4. Reservoir geology. Petrography and physical properties of reservoir in clastic and carbonate rocks; main type of oil traps (12h) .
5. Subsurface exploration and italian oil fields (4h).
6. Estimate of oil reserves and future perspectives of the unconventional oil and gas fields (4h). Didactic methods
- Teaching hours will be complemented with the microscopic study of the porosity of the main reservoir rocks. The field actvity consists on a visit to a gas well near Ravenna.
Learning assessment procedures
- - 2 written test (multiple choice answer);
- a microscope description of a reservoir rock;
- a report on the visit to the gas well;
- a final oral interview with final grade computed on the base of point average of the previous tests Reference texts
- Lecture Power Point files supplied by the teacher.
