“…Most of the data set used for simulation was taken from Bennion et al [29]. The formation is carbonaceous lying at a depth of 2050 m and consists mainly of dolomite [30]. Furthermore, the Calmar shale on top is a good cap rock, which prevents supercritical CO 2 from migrating upward into shallow aquifers.…”

Deep saline aquifers are perhaps one of the most ubiquitous sites available for CO 2 sequestration. In this study, a compositional reservoir simulator was used to evaluate the effects of various CO 2 trapping mechanisms in a saline aquifer which includes structural, solubility and mineral trapping. CO 2 was injected at a rate of 4000 m 3 /day at the bottom of the aquifer for 50 years. The results indicate that structural trapping dominated for initial 3 years, after which the maximum gas saturation and pressure was reached. During solubility trapping, the gas saturation decreased by more than 70% of the maximum saturation. Mineral trapping decreased saturation further by another 10%. In another approach, the effect of wastewater injection following injection of CO 2 was evaluated. The numerical simulations show reduction in both the amount of mobile CO 2 and its upward migration. Among the different trapping mechanisms, solubility trapping is found to be the most vital one. Multivariate analysis and optimization of the responses, viz. average gas saturation and average pressure rise, were carried out using response surface methodology. Optimized results were obtained for efficient CO 2 sequestration with lesser mobile CO 2 and pressure rise at lower values of injection rate (1000 m 3 /day), injection time (50 years), vertical-to-horizontal permeability ratio, K v /K h (0.016), and residual gas saturation (0.4).

“…These methods and frameworks have traditionally focused on project-scale injected fluid containment assurance, conformance, injection pressure and injectivity risks, with limited emphasis on the potential for generating felt induced seismicity (e.g., [5][6][7]). Such emphasis on containment and conformance with little focus on induced seismicity generation and its impacts on infrastructure and inhabitants is reflected in the published risk assessments for major fluid injection projects conducted in the Western Canadian Sedimentary Basin (WCSB) (e.g., [8][9][10][11][12][13][14][15][16][17]).…”

An Assessment of the Net Fluid Balance in the Alberta Basin

et al. 2022

Net fluid balance in the Alberta Basin has been negative over the last 60 years because extensive fluid production has consistently exceeded injection during this period. However, future gigaton-scale carbon sequestration, among other activities, can result in future cumulative fluid injection exceeding extraction (i.e., a positive net fluid balance). The in-situ net fluid balance (i.e., total fluids produced minus total fluids injected) in this basin over the period 1960–2020 shows that a liquids deficit of 4.53x109 m3 and a gas deficit of 6.05x1012 m3 currently exist. However, fluid deficits are more significant in the upper stratigraphic intervals (located more than 1 km above the Precambrian Basement) than in the stratigraphic intervals located within 1 km of the Precambrian Basement in most geographic regions. This observation indicates that greater sustainable injection capacity for large-scale fluid injection may exist in the upper stratigraphic intervals (located at more than 1 km above the Precambrian Basement), reducing the potential for generating induced seismicity of concern. Additionally, while fluid depletion rates consistently increased over most of the last 60 years in the Alberta Basin, this trend appears to have changed over the past few years. Such analysis of regional net fluid balance and trends may be useful in assessing regional sustainable fluid storage capacity and managing induced seismicity hazards.
