Feasibility of Injecting Large Volumes of CO2 into Aquifers

Initial evaluation of advantageous synergies associated with simultaneous brine production and CO2 geological sequestration

“…This pro-active pressure-relief strategy would have several advantages, including control of pressure build-up at the injection well and reduction in the size of the AoR. While this is not a new concept -the oil and gas industry has been managing pressure build-ups (and pressure losses) in reservoirs for decades -concerns about pressure build-up in CCS operations have only been considered recently, as can be seen in several recent publications (Birkholzer et al, , 2011Chabora and Benson, 2009;Ghaderi et al, 2009;Hassanzadeh et al, 2009;Keith et al, 2004;Lavoie and Keith, 2010;Nicot et al, 2009;Rutqvist et al, 2007;Zhou et al, 2008Zhou et al, , 2009. However, brine production as an integral part of a CCS operation has not been part of the broader CCS paradigm Court, 2011;Court et al, 2011a,b).…”

Screening and selection criteria, and characterisation techniques for the geological sequestration of carbon dioxide (CO2)

“…Unacceptable pressure increases identified through modelling studies could render a potential site unable to store the intended volume (van der Meer and Egberts, 2008; Ghaderi et al, 2009), leading to its rejection or to changes in overall storage strategies (e.g., use of several sites instead of just one). Relative permeability affects the pressure buildup in an aquifer, hence the pressure-induced risk during the active phase of cO 2 injection (Oruganti and Bryant, 2009).…”

Reservoir Characterization for CO2Sequestration: Assessing the Potential of the Devonian Carbonate Nisku Formation of Central Alberta

“…The locations of injection wells in the flow simulations can affect injectivity, by only the order of +/-5% at most. Horizontal drilling and hydro-fracturing, however, may double the total injection capacity (Ghaderi et al, 2009). methods using semivariograms.…”
