Class VI - Wells used for Geologic Sequestration of CO2 | US EPAUS EPA,OW,OGWDW
Measurement of the carbon alteration front was used to calculate the rate of CO2 alteration of pozzolan-amended cement exposed to a mixture of 79mol% CO2 and 21mol% H2S under geologic sequestration conditions in exposure periods of 0–90 days. Average CO2 alteration rates (rate of movement of...
No states have applied for enforcement authority for a new class of Environmental Protection Agency-regulated permitting for the geologic sequestration of CO_2, an EPA official said, a situation that could further stretch already tight agency budgets and cause more developers to shy away from the ...
