The Polish Geological Society is pleased to announce the 1st Core Logging School CoLoS, which will be held on 15-18 September, 2024 in Poland. The School is led by the Polish Geological Society in cooperation with the Institute of Geological Sciences and the Mineral and Energy Economy Research Institute of the Polish Academy of Sciences, and the Faculty of Geology, Geophysics, and Environmental Protection of the AGH University of Krakow.

The Core Logging School CoLoS will provide exposure to the theoretical background and practical skills of sedimentological borehole core logging and is designed for the Geoscientists at various stages of professional career. The CoLoS Programme integrates theory, examples of applications and practical exercises. The lectures will take place in the European Centre for Geological Education of the Warsaw University, beautifully located in the Holy Cross Mountain, in a former quarry of the Devonian dolomite (Inanimate Nature Monument; www.eceg.uw.edu.pl). The two day practical section will be held in the nearby Central Core Depository in Chmielnik. The practical will be conducted on two siliciclastic formations, deposited as shelf-margin deltas and submarine fans, the sedimentological variations of which are great for practical logging exercises and topics for discussion:
• the Ludlow Kociewie Formation from the East European Platform,
• the Miocene Machow Formation from the Carpathian Foredeep.

This three-day School will be conducted by experts with a broad experience of borehole core logging for fundamental research and applied industrial projects:


Invited to participate are Undergraduate and Postgraduate Students as well as Postdocs, Researchers, and Geoscientists from Industry and Academia.


  • Szczepan Porębski (AGH University of Krakow)
  • Marek Wendorff (AGH University of Krakow)
  • Artur Kędzior (Institute of Geological Sciences, Polish Academy of Sciences)
  • Piotr Dziadzio (Oil and Gas Institute National Research Institute)

Szczepan Porębski is Full Professor of Geology at the AGH University of Science and Technology in Kraków (Emeritus since 2024). He received MSc in Geology (1974) from the University of Wroclaw and PhD in Earth Sciences (1979) from the Jagiellonian University, Krakow. Prior joining AGH-UST in 2011, he was with the Institute of Geological Sciences of the Polish Academy of Sciences, where served as the Head of the Krakow Research Centre (1996-2009). He has held post-doctoral positions at the universities of Bergen, Göttingen, Wyoming, and Texas at Austin. He also worked as a consultant for the oil and gas industries of the North Sea, Libya and Middle East through Stavanger-based Z&S Geologi a/s and Eriksfiord a/s (1989-2010). His current research interests are aimed at using clastic sedimentology to address problems in basin analysis and hydrocarbon reservoir prediction. He has wide experience based on outcrop and well core studies in ancient aeolian, deltaic, estuarine, shelf and deep-marine depositional systems.

Marek Wendorff is Full Professor with a PhD and DSc in Sedimentary Geology from the Jagiellonian University, Kraków, Poland. He worked at the Jagiellonian, and Universities of Zambia and Botswana. Marek is currently associated with the AGH University of Science and Technology in Kraków. His research focuses on applied clastic sedimentology, facies analysis, and interplays between tectonics and sedimentation. Major projects include the Carpathian flysch, continental and marine Carboniferous-to-Jurassic suites of Svalbard/Norwegian Arctic and Proterozoic and Phanerozoic successions of Central and SW Africa. He is an author of the new tectonostratigraphy of the Central African Copperbelt, the World’s richest metallogenic province, and co-discoverer of the platinum-group element mineralisation in the Kalahari Copperbelt. Initiated and was Leader of two International Geoscience and Geoparks Programme Projects (by UNESCO-IUGS, no. 302 and 419), and collaborated with several leading Mining Houses and Exploration Companies. His experience of sedimentological borehole logging and related facies analysis ranges from the Neoproterozoic rift and foreland successions of the Lufilian Belt (Zambia and Democratic Republic of the Congo), shallow marine Mesoproterozoic of the Kalahari Copperbelt, the glacial-lacustrine-aeolian Mesozoic Karoo sequence, to the Miocene-age infill of a meteorite impact crater in the Kalahari Desert.

Artur Kędzior has been working as an assistant professor at the Institute of Geological Sciences of the Polish Academy of Sciences since 1995, where he received his PhD (2003) in Geology and DSc (2018) in Earth Sciences. He was Treasurer of the Polish Geological Society for sixteen years (2006-2023). Currently he is interested in clastic sedimentation as a tool for reconstructing the sedimentary environments of Ediacaran rocks on the western margin of the Eastern European Craton and the cyclicity of deposition during the Late Mississippian/Pennsylvanian coal-bearing succession of the Upper Silesian Coal Basin. He has worked as a consultant for Petrobaltic, PGNiG and Orlen Upstream (Polish oil and gas companies, currently part of the Orlen Group). He has experience based on outcrop and well core studies in a wide range of (Ediacaran-Jurassic) continental, deltaic, estuarine, tidal and shelf depositional systems.

Piotr Dziadzio is a Chief of Sedimentology & Structural Geology Laboratory at Oil and Gas Institute – National Research Institute in Krakow. He received an MSc in Geology (1992) from the Jagiellonian University, with a specialization in stratigraphy and prospecting, and a PhD (1999) in Earth Science from the Polish Geological Institute. He also graduated from National-Louis University School of Business in Nowy Sącz (2001) in the field of business management. In his career he worked for the Polish Academy of Sciences – Institute of Geological Sciences, Polish Oil and Gas Company, Rock Tools and Drilling Rigs (Glinik), private companies focusing on hydrocarbon exploration and production. In 2019, he was appointed Secretary of State at the Ministry of the Environment – Chief National Geologist, and then (2020-2023), undersecretary of State – Chief National Geologist and Government Plenipotentiary for State Raw Materials Policy at the Ministry of Climate and Environment.
He has a wide knowledge in the field of petroleum geology, basin analysis, petroleum system analysis, well log, and seismic analyses. In his career, he has described over 20 thousand meters of well core (carbonates and clastic). He also has experience based on an outcrop, and well core studies in the area of Carpathians and Carpathians Foredeep with a wide range of depositional systems interpretation (from shallow to deep water) based on sedimentology data.
