Towards the Uncertainty Quantification of Fractured Karst Systems: Reactive Transport and Fracture Networks: Where Numerical Modeling Meets Outcrop Observations

Society relies on large amounts of energy to progress and allow for a high standard of living. The recent severe climate changes require advanced technologies related to cleaner energy resources. One such technology beneficial for accelerating this current energy transition is geothermal energy. This type of energy is often found in fractured...

Simulation of foam in Enhanced Oil Recovery (EOR) and Carbon Capture and Storage (CCS) applications

Foam is an agglomeration of gas bubbles separated from each other by thin liquid films. Foam injection has been proved to be an efficient way to increase sweep efficiency in gas-injection enhanced-oil-recovery (EOR) processes or enlarge the storage space for trapping of CO2 in aquifers. Numerical simulation, an important tool developed by...

The impact of heterogeneity on geothermal production: simulation benchmarks and applications

Numerical simulation plays an important role for the efficient development of geothermal resources, considering all the uncertain and sensitive parameters that exist within the subsurface and during the operations. This thesis describes the numerical modeling of geothermal developments of various types and in various situations using the newly...

Delft Advanced Research Terra Simulator: General Purpose Reservoir Simulator with Operator-Based Linearization

Numerical simulation is based on space and time discretization providing a trade-off between accuracy and computational performance. The operator-based Linearization (OBL) approach introduces an additional discretization domain for the physical description of fluid and rock. Delft Advanced Research Terra Simulator (DARTS) is a general-purpose...
