This Petrogenium course aims at all those interested in understanding the impact Machine Learning will have on the Geosciences and then specifically the impact on geophysical processing and interpretation. Hence, geologists, geophysicists and petroleum and reservoir engineers, involved in exploration and development of hydrocarbon fields, but also those working in shallow-surface geophysics.

Participants will gain understanding how gravity and magnetic fields can be used to investigate subsurface structures, and to appreciate both their limitations and recent advances in these methods. Specifically, learners should be able to describe the Earth’s gravity and magnetic fields, explain how anomalies relate to density and magnetization contrasts, and recognize the non-uniqueness issues in interpreting potential-field data. Learners should also understand why gravity gradiometry and new magnetic interpretation techniques are promising developments for improving resolution and reducing ambiguity.
