Abstract

In order to complete the 2013 U.S. Geological Survey (USGS) assessment of carbon dioxide (CO 2 ) storage resources , a methodology was needed to determine the CO 2 storage efficiency of individual rock strata . The method that was used involved a storage efficiency approximation by MacMinn et al. , combined with a brine viscosity model by Mao and Duan, and thermal and pressure data from petroleum fields across basins . The resulting efficiencies indicated that both salinity of the pore fluid and the thermal gradient have a strong effect on the amount of CO 2 that strata could store.

Chemical and isotopic evidence for CO2 charge and migration within Bravo Dome and potential CO2 leakage to the southwest

Gas analyses from northeastern New Mexico, USA indicate that previous interpretations of the location of gas charge into the northeastern portion of Bravo Dome are likely correct, and that there may be multiple migration pathways from the same source for different regions in northeastern New Mexico.

A database and probabilistic assessment methodology for carbon dioxide enhanced oil recovery and associated carbon dioxide retention in the United States

The U.S. Geological Survey (USGS) has developed an assessment methodology for estimating the potential incremental technically recoverable oil resources resulting from carbon dioxide-enhanced oil recovery (CO 2 -EOR) in reservoirs with appropriate depth, pressure, and oil composition. The methodology also includes a procedure for estimating the CO 2 that remains in the reservoir after the CO 2 -EOR process is complete. The methodology relies on a reservoir-level database that incorporates commercially available geologic and engineering data. The mathematical calculations of this assessment methodology were tested and produced realistic results for the Permian Basin Horseshoe Atoll, Upper Pennsylvanian-Wolfcampian Play (Texas, USA). The USGS plans to use the new methodology to conduct an assessment of technically recoverable hydrocarbons and associated CO 2 sequestration resulting from CO 2 -EOR in the United States.

Noble gas geochemistry investigation of high CO2 natural gas at the LaBarge Platform, Wyoming, USA

A regional sampling of gases from thermal springs near the LaBarge Field, Wyoming, USA to determine the extent of the total carbon dioxide system (TCDS) indicates that the system may extend up to 70 km to the northwest of the field. Geochemical evidence from noble gas isotopes, stable element isotopes, and gas composition provide the foundation for these conclusions. Samples from Soda Springs to the west and Grand Teton National Park to the north do not exhibit the potentially diagnostic LaBarge gas chemistry and represent an absolute maximum potential extent of the system. Additional sampling to the south and east as well as in-fill sampling in regions previously sampled are necessary to refine these preliminary TCDS boundaries.
