20410889 - GEOLOGY OF SEDIMENTARY BASNS FOR ENERGY TRANSITION

The course aims to provide a theoretical-practical overview of the quantitative analysis of the spatio-temporal evolution of sedimentary basins. Starting from the different classifications of sedimentary basins, the geological and geodynamic factors that regulate their evolution will be investigated in order to realise models of burial history, subsidence, T-P and acquire the multidisciplinary analytical datasets for the calibration of the models. The study of case histories related to the retrieval of natural gas, geothermal fluids, and critical materials for the energy transition (e.g., lithium) will provide information specific to each resource. The topic of energy transition will also be contextualised in the current global scenario and in the framework of Goals 7 and 13 of the UN 2030 Agenda.

Programme

Sedimentary basins are first-order geological structures capable of hosting abundant reserves of non-renewable (e.g., oil, gas, coal) and renewable (e.g., geothermal energy) energy resources and materials critical for the energy transition. Their sustainable exploitation is of vital importance to meet the growing global energy demand in the coming decades, while respecting the environment, with particular regard to the impact of energy production on climate change, and to ensure a fast and balanced transition from fossil to renewable energy sources. The aim of the course is to provide students with a theoretical and practical basis (through the use of modern quantitative analysis techniques) for the reconstruction of the dynamics, internal architecture and thermality of sedimentary basins for 'responsible' energy exploration and production.
