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.
The United States Geological Survey and the University of Washington collaborated on a series initial experiments Lewis, Toutle, Cowlitz Rivers during September 2000 detailed experiment River May 2001 to determine feasibility using helicopter‐mounted radar measure river discharge. Surface velocities were measured pulsed Doppler radar, depth was ground‐penetrating radar. converted mean velocities, horizontal registration both velocity measurements enabled calculation magnitude uncertainty in...
Abstract The suitability of common‐offset ground‐penetrating radar (GPR) to detect free‐phase hydrocarbons in bedrock fractures was evaluated using numerical modeling and physical experiments. results one‐ two‐dimensional at 100 megahertz indicate that GPR reflection amplitudes are relatively insensitive fracture apertures ranging from 1 4 mm. experiments differences the fluids fill significantly affect amplitude polarity electromagnetic waves reflected by subhorizontal fractures. Air‐filled...
Crosshole-radar velocity tomography is increasingly being used to characterize the electrical and hydrologic properties of Earth's near-surface. Because radar methods are sensitive water content geologic materials, a good proxy for imaging soil retention in vadose zone porosity saturated zone. In many near-surface environments, varies over few orders magnitude. Common applies ray theory that assumes infinite frequency propagation. The approximation may induce modelling artefacts loss...

The U.S. Geological Survey (USGS) operates a network of about 7,000 streamflow-gaging stations that monitor open-channel water discharge at locations throughout the United States. expense, technical difficulties, and concern for safety operational personnel under some field conditions have led to search alternate measurement methods. Ground- penetrating radar (GPR) has been used by USGS in hydrologic, geologic, environmental, bridge-scour studies floating antennas on or mounting boats. GPR...
Interpreting seismic data requires inferences to be made from the geometry, character, and spatial association of reflections. Seismic attributes that highlight such associations are essential for understanding basin-fill histories. In this article, we describe two novel obtained an automatic full-volume-flattening algorithm apply them a synthetic volume experimental strata. The stratal convergence attribute colors reflections according their degree convergence, which is commonly high in...

Abstract The geologic carbon dioxide (CO2) storage resource size is a function of the density CO2 in subsurface. pressure and temperature reservoir at depth affect density. Therefore, knowing these subsurface conditions allows for improved estimates potential capacity.
