CO2 Aquifer Storage Site Evaluation and Monitoring ( CASSEM )

识别、验证和测试用于CO2封存的候选储层、密封岩石和构造圈闭的方法是英国碳捕获和封存的主要要求。WP1中提出的研究活动旨在提供最新的摘要，三维分析和样本描述选定的陆上和沿海发电站附近地下存在的基础地质构造和结构。需要这些数据来支持和交付其他合作伙伴的研究活动。1.地质数据英国陆上和邻近近海地区的地质数据有许多不同的尺度，180多年来为许多不同的目的而获得。从地震、采矿计划、钻孔和实地观察中获得的传统和现代数据集将以通用格式合并，并为地下CO2储存目的进行解释。这些数据将以数字格式捕获到岩层和横切断层的3D计算机模型中，以进行三维解释，呈现和可视化。将使用在现场区域建造的现有计算机解释，并将其扩展到与CO2储存相关。这包括查明适合储存的多孔含水层地层、将流体截留在不透水的封闭层之下的地质结构以及是否存在将封闭或破坏封闭层的断层。这将通过WP5钻孔进行测试。2.岩石性质含水层和密封层的性质将通过岩石样品进行验证。将审查档案收集中的现有样本，并确定新的样本收集地点。将收集岩石样本，包括现有钻孔和WP 5活动的材料。将提供结合光学显微镜和反向散射扫描电子显微镜进行的矿物学分析，沿着总孔隙度估计值，包括孔径分布。这将为学术伙伴提供更详细的分析和建模提供前兆数据。3.模拟表面BGS将生成计算机模拟表面，这些表面将被导出并用于石油工业计算机软件，以及从岩石样品中测量的属性，以评估地下圈闭的流体储存。这些“硬数据”也将有助于评估成功实施二氧化碳封存的任何风险。4.在英国和国际上具有丰富CO2项目工作经验的BGS工作人员将为项目提供投入，参加会议并指导交付和报告，以支持政府政策和法规。5.报告和数据存档BGS项目工作人员将根据要求提供中期报告和摘要，并为最终报告提供资料。预计该项目产生的所有数据将在国家地球科学数据中心存档和储存，供所有有关各方查阅。

The methodology to identify, verify and test candidate reservoir formations, seal rocks and structural traps for CO2 storage is a primary requirement for UK carbon capture and storage. The research activities proposed in WP1 aim to deliver up to date summaries, 3D analysis and sample descriptions of the underpinning geological formations and structures present in the subsurface adjacent to the selected onshore and coastal power generation sites. This data is required to underpin and deliver the research activities of the other partners. 1.Geological data Geological data is available at many different scales for onshore UK and adjacent offshore area and has been acquired for many different purposes for more than 180 years. Legacy and modern data sets derived from seismic, mine plan, borehole and field observation will be combined in a common format and interpreted for the purposes of subsurface CO2 storage. This data will be captured in digital format to 3D computer models of rock formations and cross-cutting faults to be interpreted, presented and visualised in three dimensions. Existing computer interpretations constructed in the site areas will be used and extended to be relevant to CO2 storage. This includes the identification of porous aquifer formations suitable for storage, geological structures that would trap fluids beneath impermeable seals and the presence of faults that would either seal or breach the trap. This will be tested by the WP5 borehole. 2. Rock properties The properties of the aquifer and seal formations will be verified from rock samples. Existing samples in archive collections will be reviewed and new sites for sample collection will be identified. Rock samples will be collected and include material from existing boreholes and the WP5 activity. Mineralogical analysis by combination of optical microscopy and back-scattered scanning electron microscopy will be provided along with estimates of total porosity including pore-size distribution. This will provide the precursor data for more detailed analysis and modelling by the academic partners. 3. Modelled surfaces BGS will generate computer modelled surfaces that will be exported and used within oil-industry computer software, together with properties to be measured from the rock samples, to assess subsurface traps for fluid storage. These 'hard data' will also contribute to the appraisal of any risks to the successful implementation of CO2 storage. 4. Provision of advice BGS staff with extensive experience in CO2 project work both in the UK and internationally will provide input into the project, attend meetings and guide delivery and reporting to support government policy and regulation. 5. Reporting and data archiving BGS project staff will provide interim reports and summaries as required and contribute to the final report. It is envisaged that the all data generated by the project will be archived and stored with the National Geoscience Data Centre and be made accessible to all interested parties.
