Access to Pore Space for Geologic Sequestration

Because of the potentially large size of commercial geologic sequestration projects, other economic uses of the subsurface, such as hydrocarbon production, natural gas storage, fl uid waste disposal, and groundwater recovery and storage activities may coexist or compete with subsurface CO

projects will overlap these other subsurface enterprises. At least in early decades this will especially be true of enhanced oil and natural gas recovery projects that inject CO

in oil and gas producing states, are already enacting GS-specifi c legislation to avoid confl ict between different economic uses of the subsurface.4
