99502 - SUBSURFACE ENERGY SYSTEMS

Conoscenze e abilità da conseguire

Al termine del corso lo studente possiede e gestisce le conoscenze di base dei sistemi energetici presenti o realizzabili nel sottosuolo (sistemi petroliferi naturali, stoccaggi di energia nel sottosuolo, incluso lo stoccaggio di idrogeno e gas naturale, tecnologie CCSU, cattura, stoccaggio e utilizzo della CO2). Questi temi rappresentano elementi strategici per il futuro dell’approvvigionamento mondiale di energia pulita. In particolare, lo studente sarà in grado di: • gestire la tecnologia utilizzata per la produzione e lo stoccaggio dei fluidi sotterranei e valutare i conseguenti impatti ambientali; • supportare e valutare le opzioni per l’utilizzo dei sistemi energetici del sottosuolo in termini di sostenibilità ambientale, sociale ed economica; • utilizzare la modellazione numerica per lo studio dei sistemi energetici del sottosuolo.

Contenuti

Part 1 (Prof. Ezio Mesini)

Origin and geology of hydrocarbons reservoirs. Overview of Exploration & Production industry (Upstream). Oil and gas exploration and drilling techniques. Petrophysical properties reservoir rocks. Thermodynamic classification of hydrocarbon reservoirs.

CCUS technologies to isolate CO₂ from heavy industry emissions, inject it into permanent underground storage sites and utilize it in the creation of high-value products like building materials and fuel. Particular focus on: 1- capture techniques, 2- transportation, 3- underground storage involving injecting captured CO₂ into geological formations, like saline formations and depleted natural gas reservoirs, for permanent storage. Enviromental issues.

Underground storage of natural gas: fundamentals, Italian field plants. Environmental issues.

 

Part 2 (Prof. Villiam Bortolotti)

Fundamentals of fluid flow in porous media. Flow equations. Simulation of reservoir behavior using numerical modeling: basic concepts of discretization, numerical simulation of single-phase and multi-phase flow, model calibration and history matching.

Some basic applications for numerical simulations of underground storage of natural gas, carbon dioxide and hydrogen. Numerical simulations in laboratory by using free software.

Metodi didattici

Classroom lectures, laboratory practice (in small groups). The lectures will focus on general aspects of oil and gas industry (upstream sector). The lectures will be supplemented with practical exercises.

Modalità di verifica e valutazione dell'apprendimento

Students must sit a written and/or oral exam comprising of a series of questions that aim to ascertain students’ understanding of the theory of the technological and design principles presented during lectures, and a practical problem similar to the ones dealt with during the practical exercises related to the course lectures.

Moreover, the exam is aimed to assess the methodological and critical skills acquired by the student. The student will be invited to discuss the topics covered during the lessons and to move within the sources and bibliographical material in order to be able to identify in them the useful information that will enable to illustrate typical aspects of the course. The achievement of an organic vision of the issues addressed during the classes and their critical use, which demonstrate ownership of a mastery of expression and specific language, will be assessed with marks of excellence. Mechanical and / or mnemonic knowledge of matter, synthesis and analysis of non-articulating and / or correct language but not always appropriate will lead to discrete assessments; training gaps and / or inappropriate language - although in a context of minimal knowledge of the material - will lead to votes that will not exceed the sufficiency. Training gaps, inappropriate language, lack of guidance within the reference materials offered during the course will lead to failed assessments.

Strumenti a supporto della didattica

Classroom classical lectures and presentations. PC simulations.
