Naturally fractured reservoir characterization
Advanced workflows for discrete fracture network modeling
Large-scale natural fracture network patterns
Insights from automated mapping in the Lilstock (Bristol Channel) limestone outcrops
The Lilstock outcrop in the southern Bristol Channel provides exceptional exposures of several limestone beds displaying stratabound fracture networks, providing the opportunity to create a very large, complete, and ground-truthed fracture model. Here we present the result of ...
Characteristics and genesis of hypogenic karsts in carbonate successions
Inferences for hydrocarbon and geothermal systems
The Morro Vermelho hypogenic karst system (Brazil)
Stratigraphy, fractures, and flow in a carbonate strike-slip fault zone with implications for carbonate reservoirs
The Morro Vermelho Cave (MVC) (Brazil) developed within the Morro Vermelho karst system, which affected Neoproterozoic limestones (Salitre Formation). The MVC experienced little interactions with meteoric processes and is an example of a hypogenic cave formed during strike-sli ...
Mapping the fracture network in the Lilstock pavement, Bristol Channel, UK
Manual versus automatic
The 100 000 m 2 wave-cut pavement in the Bristol Channel near Lilstock, UK, is a world-class outcrop, perfectly exposing a very large fracture network in several thin limestone layers. We present an analysis based on manual interpretation of fracture generations in selected do ...
Linking natural fractures to karst cave development
A case study combining drone imagery, a natural cave network and numerical modelling
In carbonate rocks, channelized fluid flow through fracture conduits can result in the development of large and connected karst networks. These cavity systems have been found in multiple hydrocarbon and geothermal reservoirs, and are often associated with high-permeability zon ...
Representing fractures explicitly using a discrete fracture network (DFN) approach is often necessary to model the complex physics that govern thermo-hydro-mechanical-chemical processes (THMC) in porous media. DFNs find applications in modelling geothermal heat recovery, hydro ...
