摘要

Fossil-fuel-based power generation in the Ohio River Valley region of the United States is responsible for large CO_2 emissions. Underlying this region is a thick sedimentary sequence consisting of saline reservoirs, deep unminable coal seams, thick sections of organic-rich shales, and oil and gas reservoirs. Under favourable conditions, these reservoirs could be used for sequestering large volumes of CO_2. However, validation and eventual utilization of this potentially very large geological sequestration capacity requires detailed site-specific geological characterization as well as injection and monitoring demonstrations. The Ohio River Valley CO_2 Storage Project is a collaborative effort (supported by U.S. Department of Energy's National Energy Technology Laboratory, American Electric Power (AEP), BP, The Ohio Coal Development Office, Schlumberger, Battelle, and Pacific Northwest National Laboratory) to investigate the reservoir potential on a regional and site-specific basis. If favourable reservoir conditions are located in close proximity to the large, stationary, carbon-emitting sites, an integrated program involving CO_2 capture, injection and monitoring could be implemented in the future. As a part of this effort, a ～2800 m deep exploratory well was drilled at AEP's 1300 MW Mountaineer Power Plant located in the Appalachian Basin. A reservoir-characterization program - involving collection and analysis of cores and formation brines, wireline logging, and reservoir testing - was implemented to identify and test potential injection and containment zones. A seismic survey was also conducted to evaluate lateral continuity and structural features of key deep formations. The results of the investigations were used to evaluate and quantify injection potential and are being used to assess feasibility of a possible future CO_2-injection and -monitoring demonstration. The findings also illustrate the need for expanded investigation of deep formations in the region, with a focus on evaluation of storage capacity, permeability, and reservoir thickness. The overall objective is to develop a detailed characterization of the potential reservoirs that may be applicable within the regional geological framework.
