Comparing carbon sequestration in an oil reservoir to sequestration in a brine formation-field study [PDF]

open access: yes, 2008
Geologic sequestration of CO2 in an oil reservoir is generally considered a different class than sequestration in formations which contain only brine. In this paper, the significance and validity of this conceptualization is examined by comparing the ...
