Workshop 1: Deep Earth Insights – Gravity/Magnetism

This workshop highlights gravity and magnetic methods applied to the exploration of deep structures in the Earth’s crust, particularly in complex geological settings. It offers targeted training on advanced processing of gravity and magnetic signals. Participants will discover integrated 3D modeling tools and recent applications in structural geology, hydrogeology, geothermal exploration, mineral prospecting, oil&gas exploration, and sedimentary basin mapping.

 Workshop 2: Exploring AI for Geosciences

This workshop aims to introduce participants to the fundamentals of artificial intelligence applied to geosciences. It will present practical use cases in geophysical data interpretation, predictive mapping, and hydrogeological modeling. Participants will gain hands-on skills to integrate AI algorithms into their scientific workflows using accessible tools and real datasets.

Workshop 3: Methodological Guide for Preparing a Geophysical Study for Water Well Drilling

This workshop provides a structured approach for designing a geophysical study report aimed at implementing water wells.

Participants will learn how to choose the appropriate geophysical methods (VES, TDEM, ERT, seismic, gravity…) according to the geological and hydrogeological context of the target area. The workshop will also cover key steps in data interpretation and the formulation of technical recommendations for drilling.

 Workshop 4: Geological Hydrogen & Deep Geophysics: A New Energy Paradigm for Tunisia’s Subsurface — Novembre 8, 2025 (9H-12H)

Project: TRAJECTOIRE – Geological Hydrogen from Groundwater (Coordinator Pr. Hakim GABTNI, CERTE-Tunisia) – Projet P2ES2024-D1P1 – Programme d’Encouragement à l’Excellence Scientifique – MESRS. 

General Context: As the global transition towards sustainable and low-carbon energy intensifies, geological hydrogen (also known as natural hydrogen) is gaining momentum as a clean, renewable, and strategically significant energy source. Tunisia, with its rich but underexplored deep geological formations, is emerging as a promising territory for the exploration and valorization of natural hydrogen, particularly from deep groundwater systems.
Workshop Objective: This workshop aims to bring together scientists, energy stakeholders, policymakers, and development partners around a new energy paradigm centered on the deep Earth’s capacity to generate and store hydrogen. It will build on the ongoing research under the P2ES2024-D1P1 project, which integrates advanced geophysical methods, deep geological studies, and strategic analysis of national potential.
