High Precision Carbon Dioxide Detection for Geological Reservoirs
Background: Large-scale sequestration of carbon dioxide in underground geological reservoirs is being actively explored as a means to sustain fossil energy use and minimize climate risks. Assuring the integrity of the huge carbon dioxide plume sequestered in such underground reservoirs is central to the viability and acceptability of this approach. It is known that carbon dioxide can leak from underground storage reservoirs. The U.S. Department of energy has set a limit on carbon dioxide leak rates of 0.01 percent per year to the atmosphere.
