“…The impact of different k r relationships and their parameters is critical to accurately predict the propagation supercritical CO 2 (scCO 2 ) and saturation distribution in a reservoir [38,39]. In this study, CO 2 BRA, a freely available database containing experimental data for rock types of different depositional environments [31,40], was utilized to correlate lithology and depositional environment of the select heterogeneous reservoir models with k r experimental data measured for corresponding core samples. The k r data for the corresponding lithology/deposition were made available in the TOUGH3 code [30] used to conduct simulations.…”

“…In this effort, heterogeneity was accounted for in the reservoir models designed for CO 2 injection using downhole well log information retrieved at pilot sites of different lithologies and depositional environments. The models are developed using the corresponding experimental relative permeability data available in the CO 2 -Brine Relative permeability Accessible (CO 2 BRA) database [31]. The heterogeneous storage efficiency values are also available in DOE-NETL's CO 2 -SCREEN tool v4.1 [3].…”

The U.S. Department of Energy’s National Energy Technology Laboratory (DOE-NETL) has been developing methods and tools (the online Carbon Dioxide Storage prospeCtive Resource Estimation Excel aNalysis (CO2-SCREEN) tool) to estimate carbon dioxide (CO2) storage potential in subsurface reservoirs. The CO2 storage efficiency terms are input in the tool to calculate storage potential in targeted reservoirs. In this effort, two CO2 storage efficiency terms were evaluated: volumetric displacement ( E V ) and microscopic displacement ( E d ). The first term deals with efficiency of CO2 propagation into an accessible reservoir volume, while the second term evaluates effectiveness of native fluid displacement with CO2. The interpreted well logs and core sample measurements were applied to create the heterogeneous reservoir models including geostatistical realizations of porosity and intrinsic permeability fields. Supercritical CO2 was injected over the course of 30 years into brine-saturated reservoir models for clastics, limestone, and dolomite lithologies and deltaic fluvial, aeolian, shallow marine, and reef depositional environments by means of varying reservoir parameters and injection scenarios. The reservoir models providing vertically heterogeneous petrophysical properties and designated as “layered reservoir models” (with homogeneous parameters along each layer of the model) were not determined to be a transition between the homogeneous and heterogeneous models in respect to storage efficiency. Another finding shows that high-efficiency factors do not necessarily mean increased CO2 storage; they rather indicate that the available volume and pore space are more fully utilized. The CO2 storage efficiency factors were evaluated dynamically at the select time points using P 10 ‐ P 50 ‐ P 90 percentiles. The results of this study show that the P 10 ‐ P 90 distribution for volumetric efficiency is wider when compared to the microscopic efficiency. It was found that where dominant buoyancy forces drive the plume to the top of a target formation, the volumetric efficiency is low. Tighter sandstone and carbonate formations show prevalence of capillary forces and better utilization of reservoir volume.

“…Fewer studies have considered intersecting fracture networks (M. Hu et al, 2016Hu et al, , 2017Hyman & Jiménez-Martínez, 2018), and only one to our knowledge has considered mineral precipitation or coupled mineral dissolution and precipitation in these environments (Feng et al, 2019). More studies have focused on characterization of intersecting fracture networks in which precipitation has occurred, including Crandall et al (2017). A large number of numerical models have been applied to analyze fluid flow (M. Hu et al, 2016;Hyman & Jiménez-Martínez, 2018), mechanics (M. Hu et al, 2017), and hydro-mechanical (Hu & Rutqvist, 2020M.…”

The critical role of fractures in governing the flow of fluid and the transport of chemical constituents in soils, sediments, and rock formations is increasingly recognized. In many near-surface and subsurface geomaterials, particularly those with relatively low permeability, fractures account for the bulk of the transmissivity because flow in the rock matrix is typically considered to be negligible. In Earth systems, fractures govern the safety and/ or the efficiency of energy recovery and storage in the subsurface such as CO 2 sequestration, geothermal exploration, and energy storage (Hu & Rutqvist, 2020. Fractures also play a crucial role in processes in shallow groundwater systems where their control on transport rates can influence drinking water quality (
