Experimental study on water–rock interactions during CO2 flooding in the Tensleep Formation, Wyoming, USA

Sorption Characteristics of CO<sub>2</sub> on Rocks and Minerals in Storing CO<sub>2</sub> Processes

“…Many researchers have investigated about mineral trapping processes among CO 2 , water, and rock in CO 2 -water-rock system [5][6][7][8][9]. However, interactions among CO 2 and rock that simulates the CO 2 rich dense phase have only been conducted by Lin et al [10].…”

Carbonate dissolution in Mesozoic sand- and claystones as a response to CO2 exposure at 70°C and 20MPa

“…Siliciclastic sediments experimentally exposed to CO 2 commonly show the dissolution of carbonate cement and feldspar grains (e.g. Pearce et al 1996;Shiraki and Dunn 2000;Bertier et al 2006;Wigand et al 2009;Ketzer et al 2009), and feldspar dissolution is supported by observations from natural analogues (e.g. Stevens et al 2001;Baines and Worden 2004).…”

“…Laboratory experiments are set up to mimic reservoir conditions, and many experiments have been conducted at or near reservoir pressures and temperatures (e.g. Pearce et al 1996;Shiraki and Dunn 2000;Bertier et al 2006;Wigand et al 2008;Ketzer et al 2009). Siliciclastic sediments experimentally exposed to CO 2 commonly show the dissolution of carbonate cement and feldspar grains (e.g.…”

Experimental and analytic studies to model kinetics and mass transport of carbon dioxide sequstration in depleted carbonate reservoirs

“…Modeling such processes require the inclusion of rate kinetic terms such as those described in this study. Simulations describing the change in mineral saturation in the vicinity of injection wells have been offered (Shiraki and Dunn, 2000) that make use of general rate equations similar to the one modeled here but assume first order kinetics (i.e. n ¼ 1) for mathematical simplicity.…”
