Roebroeks, Joppe (author)Geological surveying is a common practice performed by geologists nowadays. Determining layer orientation parameters and identifying folds are examples of features needed in order to create a geological map or model of the (sub) surface. Surveying is expensive and time consuming, therefore such survey is recently being investigated and...master thesis 2018

Feng, R. (author), Luthi, S.M. (author), Gisolf, A. (author), Angerer, Erika (author)In this paper, geological prior information is incorporated in the classification of reservoir lithologies after the adoption of Markov random fields (MRFs). The prediction of hidden lithologies is based on measured observations, such as seismic inversion results, which are associated with the latent categorical variables, based on the...journal article 2018

van Gent, Marcel (author), de Almeida Sousa, E. (author), Hofland, Bas (author)Physical model tests were performed in a wave flume at Deltares with rock armoured slopes. A shallow foreshore was present. At deep water the same wave conditions were used but, by applying different water levels, the wave loading on the rock armoured slopes increased considerably with increasing water levels. This allows the assessment of...conference paper 2018

Hofland, Bas (author), Arefin, Syed Shamsil (author), van der Lem, Cock (author), van Gent, Marcel (author)This paper describes a method to measure the rocking motion of lab-scale armour units. Sensors as found in mobile phones are used. These sensors, data-storage and battery are all embedded in the model units, such that they can be applied without wires attached to them. The technique is applied to double-layer units in order to compare the...conference paper 2018

Shen, Y. (author), Wang, Jinguo (author), Lindenbergh, R.C. (author), Hofland, Bas (author), Ferreira, Vagner G. (author)The use of a terrestrial laser scanner is examined to measure the changes of rock slopes subject to a wave attack test. Real scenarios are simulated in a water flume facility using a wave attack experiment representing a storm of 3000 waves. The stability of two rock slopes of different steepness was evaluated under the set conditions. For...journal article 2018

de Groot, L.V. (author), Fabian, Karl (author), Béguin, Annemarieke (author), Reith, Pim (author), Barnhoorn, A. (author), Hilgenkamp, Hans (author)Obtaining reliable information from even the most challenging paleomagnetic recorders, such as the oldest igneous rocks and meteorites, is paramount to open new windows into Earth's history. Currently, such information is acquired by simultaneously sensing millions of particles in small samples or single crystals using superconducting quantum...journal article 2018

Valliappan, Valliappan (author), Remmers, J. J.C. (author), Barnhoorn, A. (author), Smeulders, D.M.J. (author)In this paper, we present a two-dimensional numerical model for modelling of hydraulic fracturing in anisotropic media. The numerical model is based on extended finite element method. The saturated porous medium is modelled using Biot’s theory of poroelasticity. An enhanced local pressure model is used for modelling the pressure within the...journal article 2017

Breure, Wik (author)This thesis report presents a concept methodology to quantify the energy release associated with strain bursting in underground excavations based on the size of the failed zone and the elastic strain energy stored in the rock mass prior to failure. A strain burst implies potential harm to people and machinery and may lead to economic loss. An...master thesis 2017

Khedoe, Prashant (author)Usually, oil fields are developed over three stages. First is the primary oil recovery, where the natural underground pressure is used to drive the oil to the surface. Afterwards is the secondary oil recovery, usually by water flooding or gas injection. However, the water flood yields lower sweep efficiency in heterogeneous reservoirs, contrary...bachelor thesis 2017
