U.S. Geological Survey carbon sequestration: Geologic research and assessments

In 2007, the U.S. Energy Independence and Security Act authorized the U.S. Geological Survey (USGS) to conduct a national assessment of geologic storage resources for anthropogenic carbon dioxide (CO₂) and to evaluate the national technically recoverable hydrocarbon resources resulting from CO₂ injection and storage through CO₂-enhanced oil recovery (CO₂-EOR). In addition, the USGS is addressing several other areas of carbon sequestration research that include study of natural CO₂ and helium reservoirs as analogues for anthropogenic CO₂ storage, the economics of CO₂ storage and CO₂-enhanced oil recovery, and induced seismicity associated with CO₂ geologic storage.
