Learning objectives
The course aims to prepare students to approach to the reservoir and seal properties focusing on the sedimentary rocks.
Prerequisites
Basic (first degree) knowledge of sedimentology, stratigraphy, petrography and structural geology.
Course unit content
Living in times characterized by a growing interest toward the storage aimed to sequestrate CO2 wastes or to natural gas stokes, this course will focus on the main sedimentary, stratigraphic, structural aspects useful in the recognition of rock reservoir (in porous media and evaporitic bodies) and seals.
