- It is one of the advised courses for students attending the Master Course of Geology for Energy Resources. It aims to improve the theoretical and practical knowledge on textural features and petrophysic property of the sedimentary rocks.
The main knowledge and skills that students will acquire are:
- specific knowledge of the sedimentary rocks
- ability to evaluate the textural properties of the sedimentary rocks
- ability to recognize the original depositional areas, from the available textural data
- ability to reconstruct the diagenetic history and to predict the variability of porosity and permeability trends.
- to link the acquired knowledge to the exploration of georesources - Prerequisites
- In order to be able to understand the main subjects and to apply the majority of the techniques described in the course the students must have:
- an essential knowledge of the fundamentals of geology
- a basic knowledge in sedimentary geology
- a basic knowledge of the rocks and in particular of the sedimentary rocks and sedimentary processes
- a basic knowledge on the classification schemes of the sedimentary rocks
- confidence in the field geology (in making geologic observations and interpretations)
This precondition is valid for attending and not attending students. - Teaching methods
- The course includes theoretical lessons and practical training. It is organized as follows:
- lectures on all the subjects of the courses
- practical excerices in the laboratory: analyses of the thin sections under microscopes an on the hand samples-
- seminars and working group - Other information
- The course is recommended to students that wish to improve their knowledge on the origin, textures and diagenetic evolution of sedimentary rocks. The acquired knowledge could be applied in all the fields of sedimentary geology and, in particular, for the textural and petrophysical characterization of sedimentary rocks as reservoir for hydrocarbon, water, and for the storage of Carbon Dioxide, Hydrogen and the sustainable elements related to renewable energy sources.
- Learning verification modality
- Written and oral exam.
The exam consists of written test and practical recognignition of sedimentary rocks under microscope.
The exam aims:
- to ascertain the knowledge level and the understanding capability acquired by the students on theoretical and methodological contents listed in the program
- to verify the ability of the student to communicate with propriety of language.
- the ability to understand the problems and develop the solutions - Extended program
