Verhoeff, R.L.A. (author)Mine design and mine planning are essential to a mining operation as they do not only dictate the outline of the mine, but essentially determine the financial robustness and success of the mining operation. However, as mining is a conservative business mine design is still mostly done by hand. To indicate the effect of uncertainty in mine design...master thesis 2017

Fuciños Manrique, R.L. (author)Oil shales are sedimentary rocks containing organic matter in the form of Kerogen which accounts for more than 5 trillion barrels of oil in place according to Birol, 2010; therefore, oil shales represents a plausible solution for the constantly increasing demand for hydrocarbons. Oil shale production is currently done using two different...master thesis 2017

Sinha, T. (author)The developments in the technology and design philosophy since the first immersed tunnel was completed more than a century ago. These developments include, amongst others: the introduction of the Gina rubber gasket between elements; the division of elements into sections divided by flexible joints; various foundation methods; and the transport...master thesis 2017

Asadollahi, M. (author)When modelling fluid fl ow in subsurface, the impact of solid deformation on fluid fl ow is often oversimplified/neglected in reservoir simulators. It is assumed that solid volume/s-tate of stress is a function of fluid pressure, while the opposite effect is not considered. This assumption is made mainly to reduce computational costs and...master thesis 2017

Awadalla, T. (author)Gas flow in fractured nano-porous shale formations is complicated by a hierarchy of structural features, ranging from nanopores to microseismic and hydraulic fractures, and by several transport mechanisms that differ from standard viscous flow used in reservoir modelling. In small pores, self-diffusion becomes more important than advection, also...master thesis 2017

Bosma, S.B.M. (author)A novel multiscale method for discrete fracture modeling on unstructured grids (MS-DFM) is developed. To this end, the DFM fine-scale discrete system is constructed using unstructured conforming cells for the matrix with lower-dimensional fracture elements placed at their interfaces. On this unstructured fine grid, MS-DFM imposes independent...master thesis 2017

Leo, T. (author)Hydraulic fracturing is a stimulation method to serve the enhancement of well productivity. The fracture creates a high conductive pathway into the formation. This improves the flow performance, bypasses damage and possibly connects additional dynamic gas. In the Netherlands, 252 wells were hydraulically fractured since 1954. This constitutes...master thesis 2017

van Nass, A.F. (author)We helped archaeological research by analysing, using X-Ray μ-computed tomography (μ-CT) and X-Ray Fluorescence (XRF) data, three antique glass beads found in a cremation burial in Amersfoort. The μ-CT scans provided detailed information about the shape of the beads and their shaft and about the internal structure of the beads. Bubbles and...bachelor thesis 2017

Verhallen, G.J. (author)Sensor Based Sorting can decrease the amount of material processed in the subsequent processing steps, by separating the valuable material from the invaluable material, and therefore potentially reducing costs in those subsequent steps. For sensor based sorting to be effective, a strong relation needs to be present between the properties...master thesis 2016

Mihalache, A. (author)Modeling pile driving is a complex process, including vibrations generated from the driving hammer, propagating further through the pile and transferred to the surroundings at the pile-soil interface. The vibrations propagating through the ground interact with structures, potentially causing damage to both underground and structures at surface...master thesis 2016

Groenheide, S. (author)The St. Austell area (SW England) is known for its high quality and world-class size kaolin deposits and has a long history of kaolin mining. Mining started in the high grade zones. However, in recent years, mining is moving closer to lower grade zones and sees an increase in iron-impurities within the ore. The kaolin mineral assemblage consists...master thesis 2016

Azimi, F. (author)A series of core-flood tests were performed to evaluate the EOR potential of some immiscible N2 injection schemes. Injections were conducted either in a (1) continuous mode or (2) water-alternating-gas (WAG) mode into Bentheimer sandstone cores previously saturated with model synthetic oil. Furthermore, CT imaging has been utilized in some tests...master thesis 2016

Chin A Moei, S.A. (author)Peatlands in the Netherlands suffer from continued surface subsidence and accumulation of suspended sediments which leads to poor water quality. Excess suspended sediments are currently being deposited in depots on peatlands as a sustainable method for reusing sediment and to compensate for surface subsidence. The general consensus of...master thesis 2016

Kester, E.C.M. (author)A landfall operation is conducted whenever a pipeline reaches the shore, during this operation the pipeline is pulled onto shore with the help of a steel wire rope. Allseas engineering has experienced several cases of landfalls during which the friction forces along the steel wire rope rose to excessively high levels. These cases occurred at...master thesis 2016
