The influence of a tidal inlet system on a nearby mega-feeder nourishment

All over the world coastal communities are at risk due to sea-level rise and intensifying weather conditions. Many sandy beaches are eroding as a result of human-induced factors. Currently, the preferred coastal protection measure in the United States are beach nourishments. In Europe, there also is a general shift from hard to soft coastal...

Investigation of Gas Generation by Riverine Sediments: Production Dynamics and Effects of Sediment Properties

Due to microbial activities, the anaerobic degradation of organic matter happens in the sediments and leads to considerable gas production. Especially for low flow areas gas production is more easily fostered. To prevent the potential problems caused by gas production from the riverine sediments, this study focuses on magnitude of gas formation...

The Fracturing Behavior in Layered Rocks: Modeling and Analyses of Fractured Samples

Hydrocarbon or geothermal reservoir often consists of several rock layers from different lithology. The various lithologies have their own number of mechanical properties and the layering effect introduced the term of mechanical contrast, which represents the ratio of rock strength between adjacent layers. Mechanical contrast and confining...

Methods For Feature Extraction of an Outcrop Using Terrestrial LiDAR: Methods For Feature Extraction of an Outcrop Using Terrestrial LiDAR

The following report brings to light how LiDAR data of an outcrop can be acquired and subsequently processed in order to extract the geometry of the outcrop and its pertaining parameters. It makes the use of a sandstone outcrop in the Trooz quarry, Belgium, near Liege. The outcrop was scanned using a terrestrial laser scanner, after which the...

Non-equilibrium upscaling of compositional transport

Reservoir simulation is a broadly used tool in the oil and gas production industry. It can be used for production history matching, performance forecasting and field development. A common Enhanced Oil Recovery (EOR) method is the injection of miscible gases. With the injection of gas into an oil reservoir, the system has to be considered as...

Determination of Relevant Spatial Scale in Reservoir Simulation

Under-sampling of the subsurface combined with scale differences in observations causes the estimation of geological parameters to be an ill-posed problem. As a result, only a subset of theoretically possible models can truly depict the reality. In reservoir modeling, we capture complexity and heterogeneity by representing the solution space...
