This course is designed for geologists and geophysicists with interests in potential fields and regional tectonics. Presented as a two-day seminar, we concentrate on fundamentals for the first day and tackle advanced topics during the second day. Attendees with little previous experience in gravity and magnetics will find the pace comfortable and the concepts quite accessible. Attendees who have already worked with potential field data will find the first day to be a helpful review of basic concepts and the second day to be quite challenging and thought-provoking.

This virtual conference is open to students studying at all Latin American universities. It is open to all final year undergraduate, Masters, and PhD students across Latin America. Students who have not yet been able to present at a major conference but would like to share their work are encouraged to attend. Equally it is a great opportunity for more experienced students to present within their network. Everyone is welcome to register and attend this free conference to support their peers.

Participants will learn the uses of rock physics in interpreting the elastic properties of earth, as sensed by seismic reflections, for lithology, fluid, and porosity determination. Presented are the basics of rock physics as well as applications of rock physics at various scales – from pore to core to reservoir. Discussed are new cases studies concerning seismic-based porosity and fluid determination in clastics and carbonates. Also, presented are new developments in rock physics of gas shale. A special section is dedicated to digital rock physics and its relevance at wireline and reservoir scales.

This course presents a simple and informal discussion of the fundamental concepts which underlie the quantitative part of geophysical analysis and interpretation. These general concepts are applicable for an analytical approach to any phenomena that can be measured and recorded and includes examples and exercises created and analysed using Microsoft Excel.

This course introduces intuitive quality controls and quantitative spreadsheet analysis to plan and ensure stable depth solutions during the iterative depth-imaging process. Advanced database-validation methods, such as cross plots between horizon interpretations and well tops, are used to identify and remove inconsistencies before deriving anisotropic parameters. A related database topic is defining the polarity and phase of the seismic and investigating the importance and precision of synthetic seismogram ties using P Impedance volumes and logs.

Elastic anisotropy, widely recognized as a typical feature of sedimentary formations, has a strong influence on seismic velocities and amplitudes. For example, the difference between stacking and vertical velocity in anisotropic media most commonly is the reason for misties in time-to-depth conversion. This course provides the necessary background information regarding anisotropic wave propagation and discusses modeling, inversion, and processing of seismic reflection data in the presence of anisotropy.

Stimulations of rocks by fluid injections (e.g., hydraulic fracturing) belong to a standard reservoir-development practice. Productions of shale oil, shale gas, heavy oil, and geothermal energy require broad applications of this technology. Production of conventional hydrocarbons, carbon sequestration, saltwater disposal and development of geological gas storages require massive fluid operations in the underground as well. The fact that fluid injections and productions can induce seismicity has been well-established for several decades. Understanding and monitoring of fluid-induced seismicity is necessary for hydraulic characterization of reservoirs, for assessments of reservoir stimulation results and for controlling the seismic risk of underground fluid injections and productions. The course provides systematic quantitative rock-physical and geomechanical fundamentals of these aspects.
