Geochemical Analyses of Surface and Shallow Gas Flux and Composition over a Proposed Carbon Sequestration Site in Eastern Kentucky
Project # NT42436

Primary Performing Organization
University of Kentucky Research Foundation

This project will investigate the rates of surface gas flux and the composition of surface and shallow soil gases in areas overlying possible carbon sequestration sites in eastern Kentucky. The documentation will provide a database for interpreting the atmospheric, biologic, and geologic (microseepage) contributions to gas flux, as well as a screening tool for possible sequestration sites and a background database for monitoring changes in surface and shallow flux and composition.

Emphasis will be placed on identifying areas where microseepage is likely from a deep geologic source. Specific project objectives include:

• Construction of a Geographic Information System (GIS) database for possible sequestration sites that will include locations and Global Positioning System (GPS) coordinates for all gas wells, soil gas monitoring locations and wells, water well and spring locations with water chemistry data, and historical gas production and gas composition data for wells or field areas.
• Characterization of the carbon dioxide (CO2) and methane (CH4) gas flux and composition over possible sequestration sites using surface and shallow gas measurements.         
• Development of a more conclusive definition for areas having microseepage in the area of a “best available” sequestration site using deep soil gas composition data (stable and radiogenic isotopes, bulk composition).
