In response to the 2007 Energy Independence and Security Act, U.S. Geological Survey (USGS) conducted a national assessment of potential geologic storage resources for carbon dioxide (CO2). Storage CO2 in subsurface saline formations is one important method reduce greenhouse gas emissions curb global climate change. This report provides updates implementation details methodology Brennan others (2010, http://pubs.usgs.gov/of/2010/1127/) describes probabilistic model used calculate formations.
Injecting CO2 into depleted oil reservoirs to extract additional crude is a common enhanced recovery (CO2-EOR) technique. However, little known about how in situ microbial communities may be impacted by flooding, or if any permanent microbiological changes occur after flooding has ceased. Formation water was collected from an field that flooded for CO2-EOR the 1980s, including samples areas affected outside of flood region, determine impacts on reservoir communities. Archaea, specifically...

The injection deep subsurface sedimentary reservoirs most commonly discussed method; however, potential leakage can create long-term stability concerns. This report discusses...
The Colorado Plateau hosts several large accumulations of naturally occurring, non-hydrocarbon gases, including CO2, N2, and the noble making it a good field location to study fluxes these gases within crust atmosphere. In this study, we present compilation 1252 published gas-composition measurements. data reveal at least three natural gas associations in area, which are dominated by hydrocarbons, N2 + He Ar, respectively. Most region exhibit compositions that intermediate between end...
The middle Cretaceous greenhouse period experienced profound environmental change including episodes of enhanced global burial organic carbon marked by isotopic excursions (CIEs). However, the role and response polar regions like newly formed, partially enclosed Arctic Ocean Basin during remains enigmatic. We present first deepwater CIE record that characterizes conditions offshore Alaska margin north 75°N paleolatitude. Organic isotopes (δ13Corg) 103–82 Ma ash zircon U-Pb dates from distal...
This is a report about the geologic characteristics of five storage assessment units (SAUs) within Denver Basin Colorado, Wyoming, and Nebraska. These SAUs are Cretaceous in age include (1) Plainview Lytle Formations, (2) Muddy Sandstone, (3) Greenhorn Limestone, (4) Niobrara Formation Codell (5) Terry Hygiene Sandstone Members. The described characteristics, as specified methodology, affect potential carbon dioxide resource SAUs. specific petrophysical properties interest depth to top...

This report presents fourteen storage assessment units (SAUs) from the Alaska North Slope and two SAUs Kandik Basin of Alaska. The is a broad, north-dipping coastal plain that underlain by thick succession sedimentary rocks accumulated steadily throughout much Phanerozoic during three major tectonic sequences: Mississippian through Triassic Ellesmerian sequence, Jurassic Lower Cretaceous Beaufortian Tertiary Brookian sequence. Stratigraphic packages associated with all these sequences are...

This report presents 27 storage assessment units (SAUs) within the United States (U.S.) Gulf Coast. The U.S. Coast contains a regionally extensive, thick succession of clastics, carbonates, salts, and other evaporites that were deposited in highly cyclic depositional environment was subjected to fluctuating siliciclastic sediment supply transgressive regressive sea levels. At least nine major packages contain porous strata are potentially suitable for geologic carbon dioxide (CO2)...
Sequencing microbial DNA from deep subsurface environments is complicated by a number of issues ranging contamination to non-reproducible results. Many samples obtained these - which are great interest due the potential stimulate methane generation contain low biomass. Therefore, difficult study as sequencing results can be easily impacted contamination. In this case, amount sample biomass may effectively swamped contaminating and generate misleading Additionally, performing field work in...
