Engineering and Economic Assessment of CO2 Sequestration in Saline Reservoirs

Carbon dioxide capture and storage—liability for non-permanence under the UNFCCC

“…We consider such criteria a necessary, but not sufficient condition for the integration of CCS into the international climate regime. They do not guarantee the complete accounting of emissions, which is one of the main principles 8 Further storage cost estimates can be found in for example Gupta, Smith, Sass, Chattopadhyay, and Byrer (2002), Hendriks, Wildenborg, Blok, Floris, and Van Wees (2001), Reeves and Schoeling (2001), Smith, Gupta, Sass, and Bubenik (2001), as well as Wildenborg and Van der Meer (2002). See also IPCC (2005).…”

Geological Sequestration of Greenhouse Gases

“…The operating pressure lies between 8.62 MPa at 4 • C and 15.3 MPa at 38 • C. The upper and lower limits are set, respectively, by the ASME-ANSI 900# flange rating and ambient condition coupled with the phase behavior of CO 2 (Mohitpour et al 2000, Gupta et al 2002and Farris 1983. The minimum temperature is influenced by the elevation, depth at burial, and offshore water temperature condition for the offshore scenario.…”

“…It should not be too high to damage/fracture the reservoir, nor should it be too close to the reservoir pressure such that it is unable to penetrate the reservoir. It should be typically 9 to 18 percent above the reservoir in-situ pressure (Hendriks 1994, Gupta et al 2002. Also, a much higher pressure is possible, almost as high as 90 percent of the fracture pressure (Hitchon 1996).…”
