This course presents the fundamentals of physics and numerical simulation of wave propagation in anisotropic, inelastic and porous media, including the analogy between acoustic waves (in the general sense) and electromagnetic (EM) waves. The emphasis is on geophysical applications for hydrocarbon exploration but will also include the fields of earthquake seismology, rock physics and material science. Moreover, the course illustrates the use of seismic and EM modelling, with an account of the numerical algorithms for computing the synthetic seismograms and radargrams, including applications in the field of geophysical prospecting, seismology and rock physics, such as evaluation of methane hydrate content, upscaling techniques, detection of overpressure, Antarctic and permafrost exploration, exploration of the Earths deep crust and time-lapse for monitoring of CO2 injection.
On completion of the course, participants will be able to:
- Understand the physics of seismic (and EM) wave propagation and diffusion fields in real media, such as many types of rocks;
- Solve complex models using numerical methods, such as the finite-difference and Fourier techniques;
- Apply the concepts to seismic and EM prospecting, simulation of earthquakes, surface radar applications, EM low-frequency methods for environmental and prospection problems and rock physics.

The course is useful for geologists, geophysicists, petrophysicists, reservoir engineers, mathematicians and physicists. The emphasis is on geophysical applications for hydrocarbon exploration but researchers in the fields of earthquake seismology, rock acoustics and material science — including many branches of acoustics of fluids and solids (acoustics of materials, non-destructive testing, etc.) — may also find this course useful.
Participants should have knowledge of the basic concepts of wave theory.

Presently, he is Director of Research at OGS. He was awarded the Alexander von Humboldt scholarship for a post-doc at Hamburg University (1987-1989). In 2007, he received the EAGE Anstey award in London. He published more than 230 journal articles on acoustic and electromagnetic numerical modeling, with applications to oil exploration and environmental geophysics. He is the author of the books “Wave fields in Real Media — Theory and numerical simulation of wave propagation in anisotropic, anelastic, porous and electromagnetic media” (see (Elsevier, 2015, 3rd edition), and “Seismic Exploration of Hydrocarbons in Heterogeneous Reservoirs” (Elsevier, 2015) He has been editor of “Geophysics” since 1999. He has coordinated many projects funded by the EU and private companies. Carcione has an H-index: 49, according to Google Scholar. In 2017 he received the EAGE Conrad Schlumberger award.
Participants are recommended to preferably read "Elastic waves in the Earth" (1979) by Pilant, "Physical properties of rocks" (2011) by Schon, and "Wave fields in real media" by Carcione (2015), before attending the course.

3D printing is an emerging tool in the geoscience research, reservoir characterization, education, and technical communication. This course covers fundamentals of available techniques and materials for 3D printing and their relative merits. Participants will learn about applications of 3D printing in studies of reservoir rocks, fossils, and geomorphology. The practical section of the course will allow participants: 1) to design 3D-printable models of reservoir rocks that contain pore and fracture networks using CAD and computed tomography data; 2) to render 3D terrain models using GIS data; and 3) to test the accuracy of digital and 3D-printed models.

Hands-on microfacies characterization using industry data sets. Analysis: mineralogy, components, pore types, diagenesis. Participants are instructed on how to capture observations such that patterns and rules might be detected. The course encourages participants to think of processes and products during thin section characterization. Industry data sets are used to illustrate the use of microfacies characterization to help solve operational issues of carbonate fields. Production increase is demanded. Wells (fully cored) show contrary production behavior. The stratigraphy is ‘layer cake’ and both wells are perforated in the highest perm interval of a few meters thick. Thin sections are linked with petrophysical data, openhole logs and production data. Course participants are encouraged to use thin section descriptions to develop a conceptual model for permeability based on a depositional model architecture based on the investigation of available this sections.

Digital rock technology offers promise to overcome limitations of conventional core flooding – in particular, sensitivity to coring, core preservation, handling and preparation procedures. This course will provide an in-depth description of digital rock analysis techniques with an emphasis on the fundamentals, tools and practical methods utilized in this workflow. Advanced methods and current limitations will also be discussed. The course will then highlight how this technology can aid the geoscientist and reservoir engineer today by complementing traditional measurements and using the results intelligently to predict and interpret field-scale recovery processes. We describe examples where reconciliation and integration of the different types of data from a fundamental understanding of the pore scale has added value. In particular, the work is used to offer fast turnaround times, aided in our understanding of unconventional reservoir core material and to explain uncertainties and trends from laboratory measurements (e.g., issues with heterogeneity, representative elemental volume, wettability, distribution of remaining oil saturation, EOR processes). We conclude with a discussion on how to extend this technology for reliable prediction of petrophysical & SCAL data along continuous lengths of core material and to integrate the data with other forms of data at increasingly larger scales (log characterization, geomodels and ultimately reservoir simulators).

The field of rock physics represents the link between qualitative geologic parameters and quantitative geophysical measurements. Increasingly over the last decade, rock physics stands out as a key technology in petroleum geophysics, as it has become an integral part of quantitative seismic interpretation. Ultimately, the application of rock physics tools can reduce exploration risk and improve reservoir forecasting in the petroleum industry.
