Geomechanical laboratory investigation for the Eptachori, Pentalofos and Tsotyli formations in West Macedonia

The data comprises work under the Project Pilot Strategy GA No. 101022664, funded by the European Union. The work relates to rock samples collected in 2022 in West Macedonia, Greece. For full details, please refer to the following: Tsotyli formation: https://app.geosamples.org/sample/igsn/IE5770001 - <strong>WGS84 Lat : 40.3075, </strong><strong>WGS84 Long : 21.3354</strong> Pentalofos formation: https://app.geosamples.org/sample/igsn/IE5770002 - <strong>WGS84 Lat : 40.1332,</strong> <strong>WGS84 Long : 21.1997</strong> Eptachori formation: https://app.geosamples.org/sample/igsn/IE5770003 - <strong>WGS84 Lat : 40.1332, </strong><strong>WGS84 Long : 21.1997</strong> The focus of the work is related to CO2 storage in appropriate saline aquifers in West Macedonia. The bulk samples were shipped to IFP Energies for porosity and permeability laboratory investigation conducted by Nuclear Magnetic Resonance techniques (DOI:10.5281/zenodo.7777217). An additional set of samples were shipped to the Institute of Earth Sciences and the Department of Geosciences of the University of Évora for Geomechanical laboratory investigation for the Eptachori, Pentalofos and Tsotyli formations in West Macedonia. The Geomechanical investigation included Dynamic Elasticity Modulus, Point load and Schmidt Hammer measurements for samples collected from the Eptachori, Pentalofos and Tsotyli formations in West Macedonia. The data from this investigation are presented here.本数据集源自欧盟资助的项目试点战略计划（Project Pilot Strategy）编号GA No. 101022664项下的全部研究工作。本次研究涉及2022年于希腊西马其顿地区采集的岩石样品，详细信息如下：Tsotyli组（Tsotyli formation）：https://app.geosamples.org/sample/igsn/IE5770001，**世界大地测量系统1984（World Geodetic System 1984, WGS84）纬度：40.3075，经度：21.3354**；Pentalofos组（Pentalofos formation）：https://app.geosamples.org/sample/igsn/IE5770002，**WGS84纬度：40.1332，经度：21.1997**；Eptachori组（Eptachori formation）：https://app.geosamples.org/sample/igsn/IE5770003，**WGS84纬度：40.1332，经度：21.1997**。本研究的核心方向为西马其顿地区适宜含盐含水层的二氧化碳封存（CO2 storage）相关工作。批量样品已运送至IFP Energies，采用核磁共振（Nuclear Magnetic Resonance, NMR）技术开展孔隙度与渗透率实验室测试，相关测试的完整数据集可参考数字对象标识符（Digital Object Identifier, DOI）：10.5281/zenodo.7777217。另有一组样品被运送至埃武拉大学（University of Évora）地球科学研究所与地球科学系，针对西马其顿地区的Eptachori组、Pentalofos组及Tsotyli组开展岩土力学实验室测试，本次测试涵盖动态弹性模量（Dynamic Elasticity Modulus）、点荷载试验（Point load）及施密特锤（Schmidt Hammer）测试，本数据集即呈现该测试所得的全部数据。
