Exploration Geology

The teaching path is organized into four conceptual modules that integrate theory and practical application: From Seismic to Structural Model: Introduction to reservoirs and geological traps. Methods for seismic interpretation and the construction of structural maps, with particular attention to the representation of faults and complex geological structures. Geomechanical and Petrophysical Reservoir Characterization: Analysis of techniques for measuring seismic velocities and fundamental petrophysical properties (porosity, permeability), comparing laboratory data and well measurements. This module also covers the determination of the in-situ stress field through the study of wellbore breakouts and the assessment of wellbore stability. Faults, Pore Pressures, and Fluid Flow: Study of the role of discontinuities (faults and fractures) as conduits or barriers to fluid flow. Analysis of overpressure in reservoirs, its causes, and methodologies for its estimation, with a focus on the pore pressure regime in sedimentary basins. Reservoir Modelling and Capacity Assessment: Principles for building geological models (structural, facies, property). Introduction to the methodologies for calculating reserves and storage capacity, considering the effects of exploitation (depletion) on reservoir behaviour.

Basic knowledge of Structural Geology and Rock Mechanics is recommended.

Not mandatory but strongly suggested

The assessment of learning outcomes is carried out through a combined exam, consisting of a written test and an oral exam, each contributing 50% to the final grade. Written Test: This test assesses the ability to apply knowledge to quantitative reservoir characterization problems. The student will be required to, for example, estimate storage capacity or calculate maximum sustainable mechanical pressures, demonstrating mastery of the learned methodologies, mathematical formalisms, and calculation procedures. Oral Exam: Accessible after passing the written test with a score of ≥ 18/30, it aims to evaluate: The in-depth knowledge of reservoir geology and geomechanics principles. The ability to analyze, integrate, and critically evaluate complex datasets and geological scenarios. The command of technical language and clarity of argumentation in presenting the topics.

In addition to lectures, lab activities and an excursion are planned
