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 - WGS84 Lat : 40.3075, WGS84 Long : 21.3354 Pentalofos formation: https://app.geosamples.org/sample/igsn/IE5770002 - WGS84 Lat : 40.1332, WGS84 Long : 21.1997 Eptachori formation: https://app.geosamples.org/sample/igsn/IE5770003 - WGS84 Lat : 40.1332, WGS84 Long : 21.1997 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.

本数据集依托欧盟资助的项目试点战略计划编号GA 101022664生成，包含2022年于希腊西马其顿地区采集的岩石样品相关研究工作。详细信息如下：
措特利（Tsotyli）地层：https://app.geosamples.org/sample/igsn/IE5770001，WGS84坐标系下纬度为40.3075，经度为21.3354；
彭塔洛福斯（Pentalofos）地层：https://app.geosamples.org/sample/igsn/IE5770002，WGS84坐标系下纬度为40.1332，经度为21.1997；
埃普塔霍里（Eptachori）地层：https://app.geosamples.org/sample/igsn/IE5770003，WGS84坐标系下纬度为40.1332，经度为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（CO₂）封存。
批量岩样被运送至IFP能源研究院（IFP Energies），采用核磁共振技术开展孔隙度与渗透率实验室测试（DOI:10.5281/zenodo.7777217）。另有一批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埃普塔霍里、彭塔洛福斯及措特利地层开展岩土力学实验室测试。本次测试涵盖上述三地层采集样品的动态弹性模量、点荷载试验及施密特锤（Schmidt Hammer）测试。本数据集即收录上述测试获得的全部数据。
