Il a exercé sa carrière dans des sociétés de conseil et est, depuis 2017, directeur général de CPGF-HORIZON. Parallèlement à ses activités professionnelles, il est membre actif de la section française de l'Association internationale des hydrogéologues (AHI) et de plusieurs autres associations (Association des géologues du bassin parisien, Aquassistance, Société géologique de France). Il a travaillé en France et dans plusieurs pays africains, comme consultant ou pour des ONG (Bénin, Togo, Côte d'Ivoire, Sénégal, Niger, Maroc). 2 A01 01 A2352 Jean-Luc Mari Mari, Jean-Luc Jean-Luc Mari Jean-Luc Mari est un géophysicien qui a mené une brillante carrière en géosciences appliquées. Diplômé de l’Institut de Physique du Globe de Strasbourg et de l’IFP School (Géosciences Pétrolières, spécialisation Géophysique, 1978), il a rejoint IFP Energies Nouvelles en 1979 en tant qu’ingénieur de recherche au sein du département de Géophysique. Il a dirigé et participé à des projets de recherche majeurs en imagerie sismique haute résolution, en surveillance des réservoirs et en développement d’outils de forage, en collaboration avec des partenaires industriels tels que GDF-Suez, CGG, Total et ELF Aquitaine. Jean-Luc Mari is a geophysicist with a distinguished career in applied geosciences. A graduate of the Institut de Physique du Globe de Strasbourg and IFP School (Petroleum Geosciences, major in Geophysics, 1978), he joined IFP Energies Nouvelles in 1979 as a research engineer in the Geophysics Department. He led and contributed to key research projects in high-resolution seismic imaging, reservoir monitoring, and borehole tool development, in collaboration with industrial partners such as GDF-Suez, CGG, Total, and ELF Aquitaine. 01 eng 08 191 03 01 24 Izibook:Subject Sciences de la Terre 24 Izibook:SubjectAndCategoryAndTags |Sciences de la Terre| 20 Aquifer;seismic method;groundwater flow;Poitou;limestone;stratigraphy;geodynamic;HES;hydrogeologist 10 2011 SCI019000 10 2011 SCI032000 29 CLIL3067 01 550 05 06 06 03 00 Geophysical and hydrogeological investigations are essential for the characterization of aquifers. Drawing on their extensive experience in geophysics applied to the oil and gas industry, as well as in geotechnical and hydrogeological studies, the authors demonstrate how conventional seismic methods—commonly used in exploration and reservoir imaging—can be adapted to hydrogeological investigations, particularly in karstified geological formations. The Dogger limestone of the Poitou Threshold serves as a compelling case study.This book offers a practical guide on how hydrogeology and geophysics contribute to developing robust regional groundwater flow models. It showcases how an integrated, multidisciplinary geoscientific approach—combining geophysical, hydrogeological, and stratigraphic analyses—can significantly enhance conceptual models of groundwater flow in fractured and karstified media.The book begins with a geological overview of the Poitou Threshold and provides a detailed synthesis of the Middle Jurassic limestone stratigraphy, establishing the broader regional geodynamic context. It then focuses on the area’s hydrogeology, before presenting the Hydrogeological Experimental Site (HES). Subsequent chapters explore the geophysical and hydrogeological methods employed, emphasizing how a Multiphysics approach can delineate karstic horizons’ geometry.The book highlights the importance of high-resolution stratigraphic analysis—through core sampling and optical televiewer (OPTV) imaging from open-hole drilling—in mapping the distribution of karstic zones and refining flow models.More than just a methodological reference, this work encapsulates over two decades of research at the HES. It offers valuable insights into the sustainable management of drinking water resources, stressing the critical role of borehole stratigraphy and well completion design. The collaboration between scientists and engineers presented here exemplifies how applied geophysics can support hydrogeologists, water resource managers, and policymakers in addressing challenges such as groundwater scarcity and contamination.In addition to the detailed case study of the Dogger limestone, the authors provide a replicable framework for seismic and stratigraphic characterization applicable to a wide range of hydrogeological and reservoir studies. As such, this book serves as both a reference and a teaching tool, ideal for academic courses and professional development programs. 02 00 This book offers a practical guide on how hydrogeology and geophysics contribute to developing robust regional groundwater flow models. It showcases how an integrated, multidisciplinary geoscientific approach can significantly enhance conceptual models of groundwater flow in fractured and karstified media. 04 00 See 'Complements' 21 00 06 01 https://laboutique.edpsciences.fr/produit/1555/9782759839353/a-new-concept-of-karst-development-based-on-hydrogeology-and-geophysics 01 00 03 02 https://laboutique.edpsciences.fr/system/product_pictures/data/009/983/563/original/9782759839346-agap5-KarstDevelopment-sofedis.jpg 17 14 20260227T084113+0100 01 P1 EDP Sciences 01 01 P1 EDP Sciences 17 avenue du Hoggar - PA de Courtaboeuf - 91944 Les Ulis cedex A http://publications.edpsciences.org/ 04 11 00 20260302 01 00 20260302 19 00 20260302 2026 06 3052868830012 01 WORLD WORLD 08 EDP Sciences 04 01 00 20260302 03 01 D1 EDP Sciences 20 04 05 01 02 1 00 01 EUR
