The course provides the fundamentals of rock behaviour in relation to field operations in reservoirs. The main objective of the course is to teach students: 1) how rocks respond to the modification of the underground state of stress in relation to oil and gas production and gas storage 2) the models and methods used to solve practical problems. To reach this objective the following subjects are explained during the course: fundamentals of continuum mechanics, the role of fluids in rock behaviour, drained and undrained conditions, interpretation of laboratory tests, elasto-plastic models for predicting rock behaviour and methods of analysis for evaluating rock failure in oil and gas reservoirs.
The course provides the fundamentals of rock behaviour in relation to underground geostructures for energy production and gas storage operations. The main objective of the course is to teach students: 1) how rocks respond to the modification of the underground state of stress in relation to hydrocarbon production and gas storage 2) the models and methods used to solve practical problems. To reach this objective the following subjects are explained during the course: fundamentals of continuum mechanics, the role of fluids in rock behaviour, drained and undrained conditions, interpretation of laboratory tests, elasto-plastic models for predicting rock behaviour and methods of stability analysis for evaluating rock failure in hydrocarbon reservoirs. The subject is linked to resources geology, geophysical exploration and monitoring, reservoir modeling.
Upon completion of the course, the student should be able to: 1) Identify the appropriate rock mechanical properties and select the tests necessary to characterize the rock material with reference to a given field problem; 2) Predict the hydro-mechanical response of porous rocks in field operations; 3) Solve practical problems: wellbore stability, hydraulic fracturing, stress change induced by reservoir production and gas injection.

The course is organized in theoretical and practical lessons. During the practical lessons the students have to solve exercises by applying the theory explained in lectures. The interpretation of lab tests and the solution of practical problems are developed in the Informatic Lab

Compulsory oral exam.
The exam is aimed at evaluating knowledge, competences and skills acquired during the course. The student should be able to carry out stability analyses, to select strength parameters and to evaluate the effect of water pressure in a given case. The exam will be oral in a classroom of the Politecnico di Torino. A calendar will be published on the course page after the term for exam enrollment and every day a group of students will give the exam. The oral exam comprises 3 main questions. Questions are related to the topics explained in class. Questions consist of discussion of a given topic and/or the solution of a practical exercise.
Rules during oral exam:
>closed book;
>the equation sheet provided in the course material is allowed;
>pocket calculator and pen;
>the student must show his/her identity document
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
