SSD – ING-IND/28, 3 CFU (33 hours)
Teacher: prof. Chiara Deangeli
LEARNING CONTENTS PRESENTATION
The course aims at providing elements of advanced geomechanics for the analysis of the mechanical response of rock during oil and gas production and methane, carbon dioxide and hydrogen storage.
EXPECTED LEARNING OUTCOMES
The course aims to provide the student with the knowledge to analyze the mechanical response of the rock in the different phases of fluid production and storage and propose effective solutions
PROGRAMME
- Elements of the elasto-plastic behavior of porous material: Critical State Soil Mechanics
- Hardening Plasticity – CAM CLAY Model
- Stress Paths during production/injection
- Laboratory tests for Carbon dioxide and Hydrogen storage
- Simulation of Reservoir Compaction and Subsidence
- Carbon dioxide injection: evolution of brine-CO2 phases and related effects
- Mechanical properties of rocks from lab tests
- Caprock integrity and thermal effects
- Fault stability during production and injection
TEACHING METHODOLOGY
The course is delivered through lectures with the support of slides. After the explanation of a topic, practical examples are proposed. The student is involved to the discussion for the solution of the problem. A series of lectures is delivered by Eni Staff.
