Microseismic data from Aquistore (Canada).

This data set includes microseismic and structural geological data collected at Aquistore (Canada). They cover a period from 26th April - 21st June 2015, during which CO2 was being injected in the Aquistore injection well at 3.5 km depth. The data were collected in the framework of a research project funded by UKCCSRC (EPSRC) and based at Aquistore in order to identify whether any microseismic events, that could be related to the CO2 injection, took place during this period and use of these events to image potential flowpathways at depth. The data were collected at a sampling rate of 1000Hz using a short-period microseismic array with a 25m aperture, consisting of one three-component and three one-component sensors (Lennartz, MKIII and MKII lite). The array was placed at 50cm depth, approximately 150m away from the injection well. Acquisition was continuous during the above period. The microseismic data are available in PASCAL or ASCII format. Full details on equipment used in data collection and data formats are available in the README file. Due to commercial constraints this dataset is currently under embargo until the end of 2017.

本数据集包含加拿大阿奎斯托尔（Aquistore）场地采集的微地震（microseismic）与构造地质数据，覆盖时段为2015年4月26日至6月21日。该时段内，科研人员正通过阿奎斯托尔注入井在3.5千米深度开展二氧化碳（CO₂）注入作业。本数据由依托阿奎斯托尔场地、受工程与物理科学研究委员会（EPSRC）资助的英国碳捕获与存储研究中心（UKCCSRC）主导的科研项目采集，旨在识别该时段内是否存在与CO₂注入相关的微地震事件，并利用此类事件对深部潜在流体运移通道进行成像。数据采集采用孔径为25米的短周期微地震台阵，包含1个三分量传感器与3个单分量传感器（型号为Lennartz MKIII及MKII lite），采样率为1000Hz。台阵布设深度为50厘米，距离注入井约150米，采集工作在上述时段内持续进行。微地震数据采用PASCAL或ASCII格式存储，数据采集所用设备及数据格式的完整细节可参见README文件。受商业限制，本数据集目前处于保密期，直至2017年底方可开放获取。
