Efficiency of CO2 Foam Mobility Control with Heterogeneous Reservoir Properties
Grimstad, Alv-Arne; Klemetsdal, Øystein Strengehagen (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)We investigate how reservoir heterogeneity affects the efficiency of CO2 mobility control in saline aquifer storage. An ensemble of reservoir models is set up for simulation of CO2 injection with a quarter-five-spot well ... -
Efficient reordered nonlinear Gauss–Seidel solvers with higher order for black-oil models
Klemetsdal, Øystein Strengehagen; Rasmussen, Atgeirr Flø; Møyner, Olav; Lie, Knut-Andreas (Peer reviewed; Journal article, 2019)The fully implicit method is the most commonly used approach to solve black-oil problems in reservoir simulation. The method requires repeated linearization of large nonlinear systems and produces ill-conditioned linear ... -

Evaluating thermal losses and storage capacity in high-temperature aquifer thermal energy storage (HT-ATES) systems with well operating limits: insights from a study-case in the Greater Geneva Basin, Switzerland
Collignon, Marine; Klemetsdal, Øystein Strengehagen; Møyner, Olav; Alcanié, Marion; Rinaldi, Antonio Pio; Nilsen, Halvor Møll; Lupi, Matteo (Journal article; Peer reviewed, 2020)High-temperature aquifer thermal energy storage (HT-ATES) may play a key role in the development of sustainable energies and thereby in the overall reduction of CO2 emission. To this end, a thorough understanding of the ...
