Presentazione
Primary objectives of Petroleum Geology course are to explain selected geological principles and processes, and describe how certain petroleum reservoirs and source rocks are formed.
After a general introduction to the basic concepts of the Physical Geology the course concentrates on sedimentology, sedimentation environments and relationships with hydrocarbons generation and accumulation. The course is mainly focused to provide basic geological skills for engineers involved in the Petroleum industry. The main topics developed are: Plate tectonics, geological time and history, the fundamentals of rock formation and deformation, the essentials of various depositional environments and the reservoirs, the distribution of porosity and permeability in reservoirs produced in different depositional environments, how rock characteristics are related to modern geological processes and applied to the ancient record, petroleum reservoir and source rocks, petroleum origin, migration, and trapping. |

Organizzazione dell'insegnamento
The exercises in the final part of the course were held in small groups directly in the classroom. At the end of the course in the case of good weather it could be possible to make one-day educational tour focused on the examination of the sedimentary sequences of the Ligure-Piemontese Sedimentary Basin.
