The aim of the course consists in giving the fundamental concepts necessary to characterize, to understand and to describe analytically and numerically the behavior of fluids in porous media and, in particular the dynamic behavior of hydrocarbon reservoirs. The course is divided in some main chapters such as: reservoir fluids PVT properties; rock properties; rock fluid interaction properties; diffusivity equations for slightly compressible and compressible fluids.
The course has to be considered as introductory to most of the other course of the petroleum engineering program.

The course is divided in 55-60% of theoretical background and 40-45% of exercises in the computer laib. During the exercises the students have to approach practical problems by applying the theory discussed during the lessons.

The exam is aimed at evaluating knowledge, competences and skills acquired during the course. The exam will be oral through BBB platform. Oral questions are concerned with the theoretical parts and their application to synthetic problems. Furthermore, in order to access to the oral interview, each student has to prepare a report (word or pdf file) containing solutions of the assignments (exercises including numerical and/or symbolic calculations) given during the course. The report will be evaluated and the solution of the exercises could be part of the discussion during oral examination.
Rules during online oral exams: students must show their identification document and this will be compared with the student’s photo available in the database of the University; a witness (who is not a member of the Board of Examiners) will be present during the exam; students must declare that they are not using any aid or support tool and that nobody is in the room to help them during the exam. Student must be alone in the room, on a table clean from papers/pad /phone or whatever else than pocket calculator, white papers, and a pen. The student might be asked to share the screen during questions. If the connection is lost, the exam will have to be restarted from the beginning. It is decision of the professor to offer opportunities for redoing the exam in case of technical problems.
