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...

Naturally fractured reservoir characterization: Advanced workflows for discrete fracture network modeling

Natural fractures in subsurface rocks are a source of heterogeneity that impacts flow and transport behaviour. The presence of fracture discontinuities needs to be modelled explicitly due to observed deviations from the continuum assumption of porous media. The departures are due to both individual properties (such as aperture, infill, and...

Natural Fracture Network Characterisation: Numerical modelling, outcrop analysis and subsurface data

Responsibly using the subsurface for geo-energy extraction or storage requires an accurate understanding of the static and dynamic behaviour of the targeted reservoirs. While mostly dependent on intrinsic rock properties (e.g. porosity and permeability), this behaviour is also believed to be significantly impacted by the presence of natural...

Characterization of a Fracture-Controlled Enhanced Geothermal System (EGS) in the Trans-Mexican-Volcanic-Belt (TMVB): Predictive Mechanical Model for Fracture Stimulation in an Enhanced Geothermal System Context (EGS)

In 2020, as the world Energy demand keeps on rising (International Energy Agency (IEA), 2019), and with the global climate warming a reality (The Organisation for Economic Co-operation and Development (OECD), 2020), reducing our societal impact on Earth is of utmost importance. Energy and Climate have always been intrinsically related. Therefore...

Phanerozoic Vertical Movements in Morocco

Our understanding of the Earth’s interior is limited by the access we have of its  deep layers, while the knowledge we have of Earth’s evolution is restricted to harvested information from the present state of our planet. We therefore use  proxies, physical and numerical models, and observations made on and from the...

Burial-related fracturing in sub-horizontal and folded reservoirs: Geometry, geomechanics and impact on permeability

Multi-scale Fracture Analysis from an Outcrop Analogue: A Case Study from the Cambro-Ordovician Sequence in Petra, Jordan

Natural fractures occur over several orders of size magnitude. Accurately predicting the three-dimensional and multi-scale distribution of fractures in subsurface reservoirs is very difficult. Direct observations are limited to large-scale faults visible on seismic data and high-resolution, mostly small-scale, measurements of fractures...
