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、验证和测试二氧化碳储存的候选储集层、封闭岩和构造圈闭的方法是英国碳捕获和储存的主要要求。WP1中提议的研究活动旨在提供有关选定的陆上和沿海发电地点附近地下存在的支撑地质构造和结构的最新摘要、3D分析和样本说明。这些数据是支持和提供其他合作伙伴的研究活动所必需的。1.地质数据英国陆上和邻近近海地区有许多不同规模的地质数据，180多年来，出于许多不同的目的获取了这些数据。来自地震、矿山平面图、钻孔和现场观测的遗留和现代数据集将以一种通用格式合并，并为地下二氧化碳储存的目的进行解释。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，以便在三维中进行解释、呈现和可视化。在工地地区建造的现有计算机解释将被使用并扩展到与二氧化碳储存相关。这包括确定适合储存的多孔含水层、将流体困在不透水密封层之下的地质结构以及是否存在封堵或破坏圈闭的断层。这将通过WP5井眼进行测试。2.岩石性质将从岩石样本中核实含水层和盖层的性质。将审查档案收藏中的现有样本，并确定新的样本收集地点。将收集岩石样本，包括来自现有钻孔和WP5活动的材料。通过光学显微镜和背向散射扫描电子显微镜相结合的矿物学分析，将提供总孔隙度的估计，包括孔径分布。这将为学术伙伴进行更详细的分析和建模提供先兆数据。3.模拟表面BGS将生成计算机模拟表面，这些表面将被输出并在石油工业计算机软件中使用，以及将从岩石样本测量的性质，以评估用于流体储存的地下圈闭。这些“硬数据”还将有助于评估成功实施二氧化碳封存的任何风险。4.提供咨询意见BGS工作人员在英国和国际上都有丰富的二氧化碳项目工作经验，将为项目提供投入，出席会议，并指导交付和报告，以支持政府的政策和法规。5.报告和数据存档BGS项目工作人员将根据需要提供临时报告和摘要，并为最后报告作出贡献。据设想，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，所有有关各方都可查阅。
