PETROPHYSICS

Academic Year 2023/2024 - Teacher: Rosalda PUNTURO

Expected Learning Outcomes

Knowledge and skills for understanding the physical properties of minerals and crustal and mantle rocks, the methodologies aimed to the petrophysical characterization of rocks, the fields of applications of petrophysics and the planning of petrophysical investigations.

Course Structure

Interactive classes; practical activities. Problem solving teaching method.

Required Prerequisites

Knowledge of the topics covered in petrography, structural geology, geophysics.

Attendance of Lessons

Attending lessons is a fundamental requirement for an informed and constructive educational path. Course attendance is mandatory and this is explicitly mentioned in the Official Study Plan. Attendance is considered acquired if the student has attended at least 70% of the curricular hours envisaged by the discipline.

Detailed Course Content

Physical properties of rock-forming minerals. Elastic properties of rocks and their relationship with textural and compositional properties as a function of pressure and temperature. Role of shape parameters: elongation, crystal preferred orietnations, modal composition etc.Extrinsic and intrinsic parameters. Mono- and poly-crystal aggregates. Physical properties of rocks (e.g. Vp, Vs, seismic anisotropy, density, magnetism).Porosity: role of pores and microfractures. Interpretation od petrophysical data obtained either from outcrops and from boreholes. Applications to geological modeling. CAse studies. Overview of applications to georesources and cristical materials and to Cultural heritage studies. Overview of main methodologies adopted in petrophysical studies.
