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.

识别，验证和测试候选储层地层，密封岩石和二氧化碳陷阱的方法是英国碳捕获和存储的主要要求。 WP1中提出的研究活动旨在提供最新的摘要，3D分析和对与所选陆上和沿海发电站相邻的地下中存在的基础地质形成和结构进行样本描述。这些数据是为了支撑其他合作伙伴的研究活动所需的数据。 1.地质数据地质数据在许多不同的尺度上可用于英国陆上和邻近的海上区域，并且已用于许多不同的目的已有180多年的历史。从地震，矿山计划，钻孔和现场观察得出的遗产和现代数据集将以通用格式组合，并为地下CO2存储而解释。这些数据将以数字格式捕获到岩层的3D计算机模型，以及要在三个维度上解释，呈现和可视化的横切故障。将使用并扩展在站点区域中构建的现有计算机解释与二氧化碳存储相关。这包括识别适合存储的多孔含水层地层，地质结构，这些结构会在不可渗透的密封下捕获流体，以及存在会封闭或破坏陷阱的断层。这将由WP5钻孔测试。 2。岩石性能将从岩石样品中验证含水层和密封地层的性质。将审查存档集中的现有样本，并确定样本收集的新站点。将收集岩石样品，并包括现有钻孔和WP5活性的材料。通过光学显微镜和背面扫描电子显微镜组合结合的矿物学分析以及总孔隙度（包括孔径分布）的估计值。这将为学术合作伙伴提供更详细的分析和建模提供前体数据。 3。建模的表面BGS将生成计算机建模的表面，这些表面将在油行业计算机软件中导出和使用，以及从岩石样品中测量的属性，以评估地下陷阱以存储流体。这些“硬数据”还将有助于评估成功实施CO2存储的任何风险。 4。在英国和国际上在二氧化碳项目工作中拥有丰富经验的BGS员工提供建议，将为该项目提供意见，参加会议，指导交付和报告以支持政府的政策和法规。 5。报告和数据归档BGS项目人员将根据需要提供临时报告和摘要，并为最终报告做出贡献。可以预见，该项目生成的所有数据将与国家地球科学数据中心一起存档并存储，并将所有有关方面访问。
