Een vuursteen uit de zilverzandgroeve van Beaujean in Heerlerheide lag 30 jaar veronachtzaamd in de stenenverzameling van Hans Erren. Een artikel van Hans de Kruyk over microfossielen in vuursteen van januari 2018 in Grondboor & Hamer startte de ontdekkingstocht naar de oorsprong van deze bijzondere steen. In de loop van het onderzoek werden...

Understanding how the hydrological regime in relation to sediment type interferes with ecosystem development is important when wetlands are created with soft muddy material. Especially when plants are used as ecological engineers to promote crest stability and soil formation. We carried out a two-year mesocosm experiment with sediments derived...

Artificial sand replenishments are globally used as innovative coastal protection measures. In these replenishments elevated porewater concentrations of trace elements are found. The present study investigated possible ecotoxicological risks at 2 intertidal depositional sites, the Sand Engine as a recent innovative Dutch coastal management...

Non-hydrocarbons (H2S, CO2, N2) reduce the economic value of natural gas accumulations. This paper presents new approaches to evaluate the probability to encounter high amounts of non-hydrocarbons. These approaches were developed as one of the deliverables of a 2-year JIP project carried out by TNO from September 2014-July 2016. The newly...

Nederland en Duitsland hebben eind 2016 de paden voor hun geplande energietransitie tot 2050 weer verder uitgestippeld. In Nederland gebeurde dat met de ‘Energieagenda’, in Duitsland als onderdeel van het ‘Klimaschutzplan 2050’. De doelen van beide plannen zijn vergelijkbaar, maar de wegen daarnaartoe verschillen. Het is daarom niet...

The evolution of friction as a function of slip rate is important in understanding earthquake nucleation and propagation. Many laboratory experiments investigating friction of fault rocks are either conducted in the low velocity regime (10−8–10−4 ms−1) or in the high velocity regime (0.01–1 m s−1). Here, we report on the evolution of friction...

Laboratory and numerical studies, as well as field observations, indicate that phase transitions of pore water might be an important process in large earthquakes. We present a model of the thermo‐hydro‐chemo‐mechanical processes, including a two‐phase mixture model to incorporate the phase transitions of pore water, occurring during fast slip (i...

The Permian Rotliegend Slochteren Formation is a prolific gas bearing interval in the Netherlands. However, their reservoir porosity and permeability can be locally severely degraded by diagenetic pore-blocking cements. This work focusses on the cementational control on the reservoir quality. The drivers and causes of cementation and its effect...

Fault slip surfaces and earthquake surface ruptures are not flat but show corrugations at all scales, also called roughness. These corrugations control the distribution of stress and strength on the fault plane and around. Here, we review the scaling properties of faults and earthquake slip roughness. Interestingly, both fault and earthquake...

Exploration for hydrocarbons in the NE Atlantic mainly focuses on the central eastern margin. The western margin has remained virtually unexplored, with no exploration wells drilled so far. A cost-efficient way to infer the presence of natural hydrocarbons in the poorly explored regions of the NE Atlantic is the application of synthetic aperture...

We construct theoretical models for time-dependent swelling of coal matrix material upon adsorption of a single gas, taking into account a coupling between stress, strain, chemical potential, and diffusion. Two models are developed. The first (model A) corresponds to diffusion and hence swelling rates being controlled by the jump frequency of...

In preparation for future requirements to abate CO2 emission levels, a CO2 storage feasibility study was carried out for the country of Kuwait. At present, no definite plans exist to install capture facilities at the larger emission points in the country; the study presented is one of the first steps to prepare the country for a low-carbon...

To enhance protection and maintain wide beaches for recreation, beaches are replenished with sand: socalled beach nourishments. We compared four sites: two traditional beach nourishments, a mega beach nourishment and a reference without beach nourishment. Two sites contain calcareous-rich sand, whereas the other two sites have calcareous-poor...

Enhanced weathering of olivine has been suggested as a measure to lower the atmospheric CO2 level and it might also mitigate ocean acidification. This study aimed to characterise how olivine can weather in seawater, to elucidate the role of secondary precipitation and to ascertain the efficiency in terms of molar CO2 removal per mole of olivine...

As coastal lowlands are prone to sea water flooding, sea-level rise might globally increase this risk. To protect its coastline, the Netherlands adds an average of 12 million m3 of sand annually, but more is needed to cope with the expected consequences of global warming. In 2011 a novel approach for coastal protection was applied near The Hague...

Blowouts present a small but genuine risk when drilling into the deep subsurface and can have an immediate and significant impact on the surrounding environment. Nevertheless, studies that document their long-term impact are scarce. In 1965, a catastrophic underground blowout occurred during the drilling of a gas well in The Netherlands, which...

Na de ontdekking van het Groningen aardgasveld in 1959, het grootste gasveld in West-Europa, is Nederland meer dan een halve eeuw zelfvoorzienend geweest met deze energiebron. Het keerpunt kwam door de aardbeving in Huizinge in de provincie Groningen in augustus 2012 met een kracht van 3,6 op de schaal van Richter die gebeurtenis heeft geleid...
