Hydrogen diffusion into caprock: A semi-analytical solution and a hydrogen loss criterion
(Peer reviewed; Journal article, 2023)Depleted gas reservoirs can provide a gigaton capacity and the necessary infrastructure for large scale hydrogen storage. Therefore, underground storage of hydrogen in these geological formations is considered a valuable ... -
Hyper-parameter optimization for improving the performance of localization in an iterative ensemble smoother
(Peer reviewed; Journal article, 2023)This work aims to help improve the performance of an iterative ensemble smoother (IES) in reservoir data assimilation problems, by introducing a data-driven procedure to optimize the choice of certain algorithmic ... -
Characterization and capillary pressure curve estimation of clayey-silt sediment in gas hydrate reservoirs of the South China Sea
(Peer reviewed; Journal article, 2023)The capillary pressure curve is a crucial basis for studying the pore structure and multiphase flow characteristics in oil and gas reservoirs. Due to the loose and unconsolidated nature of the clayey-silt sediment of natural ... -
Evaluation of Surface-Active Ionic Liquids in Smart Water for Enhanced Oil Recovery in Carbonate Rocks
(Peer reviewed; Journal article, 2023)Ionic modification of injected brines (Smart Water EOR) has previously demonstrated great potential for wettability alteration in carbonates from initially mixed-wet toward more water-wet conditions. However, the efficiency ... -
Structural geologic modeling and restoration using ensemble Kalman inversion
(Peer reviewed; Journal article, 2023-06)We demonstrate the use of Ensemble Kalman Inversion (EKI) for building three-dimensional, multi-fault, kinematically restorable structural geologic models, by means of a workflow in which fault geometry, the distribution ... -
cdem: A macOS program for discrete element modeling of tectonic structures
(Peer reviewed; Journal article, 2023-08)cdem is a macOS document-based application for two-dimensional discrete element modeling of tectonic structures and their associated deformation. Documents encapsulate simulations that can be run and explored simultaneously. ... -
A Second-Order Finite Volume Method for Field-Scale Reservoir Simulation
(Peer reviewed; Journal article, 2023-08)Subsurface reservoirs are large complex systems. Reservoir flow models are defined on complex grids that follow geology with relatively large block sizes to make consistent simulations feasible. Reservoir engineers rely ... -
Numerical investigation on blast-induced rock fragmentation with different stemming structures
(Peer reviewed; Journal article, 2023-09)Stemming is one of the main concerns in blast of rock engineering due to its impact on explosion energy consumption and rock excavation performance. In this study, blast-induced rock fragmentation under different stemming ... -
Ostwald ripening of gas bubbles in porous media: Impact of pore geometry and spatial bubble distribution
(Peer reviewed; Journal article, 2024)We study pore-scale gas bubble ripening in porous media by combining a mass transfer method based on chemical potential differences with a level-set method for updating the gas/liquid configurations. We examine the impact ...
