The ability to accurately predict the CO₂ storage resource in saline formations is important to make high-level, energy-related government policy and business decisions. CO₂-SCREEN (Storage prospeCtive Resource Estimation Excel aNalysis) is a tool developed by the United States Department of Energy − National Energy Technology Laboratory (US-DOE-NETL) to screen saline formations for prospective CO₂ storage resources. CO₂-SCREEN uses DOE methods and equations to serve as a consistent mechanism for calculating prospective CO₂ storage resources. CO₂-SCREEN is comprised of two files: an Excel file used for inputs and outputs and a GoldSim Player file used to run Monte Carlo simulations. CO₂-SCREEN requires input of physical geologic parameters (i.e. thickness, porosity) as well as efficiency factor ranges (i.e. net-to-gross thickness) to calculate a mass storage estimate. An application of CO₂-SCREEN is demonstrated here using well log data from the Oriskany Sandstone portion in Pennsylvania. The Oriskany Sandstone is divided into 20 km x 20 km grid cells in which 151 cells contain well log data. CO₂-SCREEN calculates prospective CO₂ storage resource for each grid cell based on the well log data and uses lithology and depositional environment information for efficiency factor ranges. The Oriskany Sandstone CO₂ storage resource estimate for Pennsylvania, calculated by CO₂-SCREEN, ranges from 0.07 to 1.28 gigatons (Gt) with a P₅₀ value of 0.32 Gt. This resource assessment analysis is done to demonstrate the use of CO₂-SCREEN and results are comparable to previous studies which encourages the application of CO₂-SCREEN to other saline formations and warrants exploring the expansion of this tool to assess the CO₂ storage resource in other formations such as shale and depleted oil and gas reservoirs.

准确预测盐层中CO ₂储存资源的能力对于制定高层的，与能源有关的政府政策和商业决策很重要。CO ₂ -SCREEN（存储专用资源估算Excel分析）是由美国能源部-国家能源技术实验室（US-DOE-NETL）开发的工具，用于筛选盐分中的潜在CO ₂存储资源。CO ₂ -SCREEN使用DOE方法和方程式作为计算预期CO ₂储存资源的一致机制。一氧化碳₂-SCREEN由两个文件组成：用于输入和输出的Excel文件和用于运行蒙特卡洛模拟的GoldSim Player文件。CO ₂ -SCREEN需要输入物理地质参数（即厚度，孔隙率）以及效率因子范围（即净毛厚度）才能计算出大容量存储估算值。本文使用宾夕法尼亚州Oriskany砂岩部分的测井数据演示了CO ₂ -SCREEN的应用。Oriskany砂岩被分为20 km x 20 km的网格单元，其中151个单元包含测井数据。CO ₂ -SCREEN计算预期的CO ₂根据测井数据为每个网格单元存储资源，并使用岩性和沉积环境信息作为效率因子范围。由CO ₂ -SCREEN计算得出的宾夕法尼亚州的Oriskany砂岩CO ₂储存资源估算范围为0.07至1.28千兆吨（Gt），P ₅₀值为0.32 Gt。进行该资源评估分析是为了证明CO ₂ -SCREEN的使用，其结果与以前的研究相当，后者鼓励将CO ₂ -SCREEN应用于其他盐层，并保证探索该工具的扩展以评估CO _2的储存资源在其他地层中，例如页岩和枯竭的油气藏。
