Fluid pH and major and minor element data from shale-acidic fluid interaction laboratory experiments

This dataset presents major (ICP-OES) and minor (ICP-MS) element data and fluid pH during interaction of simulated fracturing fluids with the Bowland-Hodder shale at a variety of conditions, i.e. fluid acidity (pH 1-5), temperature (25-70 C), and rock/fluid ratio (from 0.2:200 to 20:200), as well as two end member mineralogical compositions (from 618 m depth and 673 m depth). The data was collected under the SECURe (Subsurface Evaluation of Carbon capture and storage and Unconventional Risk funded under the European Union’s Horizon 2020 research and innovation programme under grant agreement number 764531.

本数据集收录了模拟压裂液与鲍兰德-霍德页岩 (Bowland-Hodder shale) 在多种实验工况下相互作用过程中的主量元素（电感耦合等离子体发射光谱法，ICP-OES）与微量元素（电感耦合等离子体质谱法，ICP-MS）检测数据，以及流体pH值。所涉及的实验工况包括流体酸度（pH 1~5）、反应温度（25~70℃）、岩液比（0.2:200至20:200），以及两类采自618米和673米深度的端元矿物组成样品。本数据集的数据由欧盟“地平线2020”研究与创新计划（资助协议编号764531）资助的SECURE（Subsurface Evaluation of Carbon capture and storage and Unconventional Risk）项目采集，经诺丁汉大学 (University of Nottingham) 与英国地质调查局 (British Geological Survey) 许可提供。
