This report serves as the final technical report and users manual for the "Rigorous Screening Technology for Identifying Suitable CO 2 Storage Sites II" SBIR project. Advanced Resources International has developed a screening tool by which users can technically screen, assess the storage capacity and quantify the costs of CO 2 storage in four types of CO 2 storage reservoirs. These include CO 2 -enhanced oil recovery reservoirs, depleted oil and gas fields (non-enhanced oil recovery candidates), deep coal seems that are amenable to CO 2 -enhanced methane recovery, and saline reservoirs. The screening function assessed whether the reservoir could likely serve as a safe, long-term CO 2 storage reservoir. The storage capacity assessment uses rigorous reservoir simulation models to determine the timing, ultimate storage capacity, and potential for enhanced hydrocarbon recovery. Finally, the economic assessment function determines both the field-level and pipeline (transportation) costs for CO 2 sequestration in a given reservoir.The screening tool has been peer reviewed at an Electrical Power Research Institute (EPRI) technical meeting in March 2009. A number of useful observations and recommendations emerged from the Workshop on the costs of CO 2 transport and storage that could be readily incorporated into a commercial version of the Screening Tool in a Phase III SBIR.Final Report, DE-FG02-04ER83889 "Rigorous Screening Technology for Identifying Suitable CO2 Storage Sites II" iv sequestration to assess potential underground CO 2 storage sites. These potential beneficiaries of the "Screening Tool" include the following: List of Tables The major beneficiary would be the public at large, by having greater assurance that sites selected for CO 2 storage would be reliable and safe. The large group of electric power plant operators, high volume CO 2 industrial plant managers, and other industrial firms that emit CO 2 . These firms would have a rigorous, ready to use set of tools for evaluating the CO 2 storage options available for their plants and thus be able to select the most cost-effective and secure option(s). Governmental entities that would be responsible for the permitting, approval and oversight of CO 2 storage sites. These entities would have a more reliable set of protocols and tools by which to approve a proposed CO 2 storage site. CO 2 Storage ApplicationsThe "Screening Tool" contains the capacity to evaluate four major types of largescale underground CO 2 storage options:CO 2 -Enhanced Oil Recovery (CO 2 -EOR) in depleted oilfields that are technical candidates for EOR (i.e., they meet the pressure, temperature, and oil gravity standards to technically screen for CO 2 -EOR). In addition to CO 2 storage in the reservoir, the model also calculates the volume of oil recovered during EOR, an important parameter for evaluating the costs and provide net revenues from using this CO 2 storage option.CO 2 -Enhanced Coalbed Methane (ECBM) in unmineable coal seams. In addition to CO 2 storage in the coal ...
