Comprehensive analysis of an ongoing CO2 storage project
Increase in CO2 emission has become an important issue over the years due to its environmental impacts as a greenhouse gas. The fact that these emissions are primarily derived from energy consumption and that 85% of the primary power is supplied by fossil fuels (Orr, 2004), makes the reduction of …

Regional stratigraphic framework of the Tuscarora Sandstone: A model for geologic CO2 storage in West Virginia
… of the regional resource potential for geologic storage of anthropogenic greenhouse gases, primarily CO2, is an essential first step in developing policies for carbon management. Within the central Appalachian basin the Lower Silurian Tuscarora Sandstone, a gas producing anticlinal play, has been …

Effect of halite (NaCl) on sandstone permeability and well injectivity during CO2 storage in saline aquifers
Carbon dioxide capture and storage (CCS) is one of the widely discussed options for decreasing CO2 emissions. This method requires the techniques for capturing purification of anthropogenic CO2 from fossil-fuel power plants, subsequent compression and transport, and, ultimately, its storage in deep …

The liability of carbon dioxide shortage
This research examines the liability of storing CO2 in geological formations. There is a potential tortious and contractual liability exposure if stored CO2 is not fully contained by the geological formation. Using a combination of case study and survey methods, this research examines the risks …

A Pre-Feasibility Assessment of Geologic CO₂ Storage, Offshore Corpus Christi
Carbon capture and storage (CCS) is a technology to capture CO2 emissions from industrial point-source facilities and store the CO2 in deep geological formations in perpetuity. The Gulf of Mexico is a region of interest for CCS development, as it contains laterally extensive reservoir-seal systems …

Monitoring for Enhanced Gas and Liquids Recovery from a CO2 'Huff-and-Puff' Injection Test in a Horizontal Chattanooga Shale Well
Permanently sequestering carbon dioxide (CO2) in gas-bearing shale formations is beneficial in that it can mitigate greenhouse gas emissions as well as enhance gas recovery in production wells. This is possible due to the sorption properties of the organic material within shales and their greater …
