Reservoir Heterogeneity Effect on CO2 Storage: Investigate the effect of carbonate-cemented layers in the Roda Sandstone on the migration of the CO2 plume at a short-term timescale using RRM and DARTS

The storage of carbon dioxide is now regarded as a critical industrial application aimed at mitigating its accumulation in the atmosphere. Reservoirs and aquifers have been identified as viable alternative locations. This report seeks to examine the impact of sedimentological heterogeneity on the development and migration of CO2 plumes over time...

Numerical and Experimental Investigation of CO2 Hydrates on Injectivity Decline

The increasing levels of carbon dioxide (CO2) emissions in the atmosphere are significantly contributing to climate change. One approach to mitigate this issue is through Carbon Capture and Storage (CCS) techniques, which involve storing CO2 emissions underground. Depleted reservoirs are a potential option for subsurface CO2 storage. However, a...

Data assimilation for geothermal doublets using production data and electromagnetic observations: Assimilation of production and EM data

The data assimilation process for geothermal reservoirs often relies on well data which primarily offers insights into the immediate vicinity of the borehole. However, integrating geophysical methods can provide valuable information beyond well proximity, possibly enhancing reservoir predictions. Electromagnetic methods can be sensitive to the...

A cohesive-frictional mechanical constitutive law for zero-thickness interface elements: Expanding the cohesive zone model by including friction to better model fracture development along discontinuities in geomaterials

Discontinuities have an important influence on the bulk behaviour of geomaterials. Discontinuities can be physical openings like fractures and joints, interfaces between different material types, or zones with different material behaviour like mortar or reinforcement material. Bulk material behaviour is often determined by the behaviour of the...

Coupling ORCHESTRA to Python: A modelling framework for simulating waste degradation in a bioreactor

Over the years, modelling frameworks have been proposed to describe and predict the degradation of municipal solid waste in landfills. These frameworks, however, fail to couple the kinetic solutions to the real-time equilibrium state of the system. Because of this, fundamental processes such as pH changes, NH4+ adsorption to the waste surface...

A Multi-Scale Reservoir Characterization of the Main Buntsandstein Subgroup in the Tilburg Area for Geothermal Operations

The rising demand for clean energy has drawn the attention for more geological research to low enthalpy geothermal applications in the Netherlands. A multi-scale reservoir characterization is carried out with the aim to understand the geothermal reservoir potential of the Triassic Main Buntsandstein (RBM) in the Tilburg area. Seismic data, well...

Assessment of the usability of OpenGeoSys tools for Aquifer Thermal Energy Storage (ATES) simulations

Aquifer thermal energy storage (ATES) is an energy efficient technology to temporarily store groundwater of different temperatures in an aquifer. The basic idea behind ATES is to store thermal energy in warm and cold wells so that the energy can be used for heating and cooling of buildings in the next season. Design and planning of ATES systems...

A Numerical Study of Swirl Flow in Pipes: Application to Inline Swirl Separators

For many decades, conventional gravitational separators have been the backbone of the fluid separation in the oil and gas industry. The stricter environment regulation for purification of the recycled water, together with a tighter profitable margin of the produced oil, requires more efficient and faster separators. Inline swirl separator uses...

Reservoir Simulation for Play-based Development of Low Enthalpy Geothermal Resources: Application to the Delft Sandstone

As implementation of deep geothermal energy projects in the Netherlands increases, reservoir simulation for these geothermal systems stands to play a key role in understanding how these systems will behave and how large scale projects can be optimised to save cost and reduce risk. In this thesis, an extensive simulation study has been conducted...

Tie-Simplex Parameterization of Operator Based Linearization for Isothermal Multiphase Compositional Flow In Porous Media

Compositional flow simulation is the best practise to model the complex enhanced oil recovery process. This involves solving highly coupled and non linear flow, transport equations.<br/>Interaction of components within different phases and the fluid interaction with rock properties makes it difficult to accurately predict the natural flow...
