Kalpoe, I.R. (author)Case II (super)-diffusion is characterized by a diffusion like process that goes faster than the square root of time. Superdiffusion can occur in polymeric structures if a stress gradient enhances the diffusion process. In such a case the part of the polymer invaded by the penetrant, e.g. CO2, undergoes a transition in structure from the glass...bachelor thesis 2009

Slangen, G.L.J. (author)When an oil reservoir is underlain by an aquifer, oil production draws the water from the aquifer upward, forming a water cone, which under adverse conditions enters in the production well leading to high water cuts. An alternative option is to produce above the critical rate from the aquifer, i.e., at such a rate that the oil cone is drawn into...bachelor thesis 2012

Deen, M.M. (author)The objective of thesis is to see at which rate and depth Arsenic (As) contaminated water flows into deep wells in the subsurface of a small region in Bihar, India. The method of investigation is interpretation of geological data and implementing this in a flow model built in Comsol Multiphysics 4.2a. Interpretation of the data is done by grain...bachelor thesis 2012

Den Boer, C.A. (author)In the “Delft Aardwarmte Project” cooled geothermal water is planned to be injected back into the producing formation. This paper describes the mechanisms occurring during injection and he prediction of the thermal breakthrough that are studied using a reservoir simulation model developed for the “Delft Aardwarmte Project” field properties....bachelor thesis 2009

Burgers, Floortje (author)Natural occurring arsenic contamination of shallow aquifer groundwater is a problem affecting millions of people worldwide. Long term exposure to high concentrations results in severe medical conditions. On-going research into the origin and spread of the problem, risk mitigation and problem solving is of great importance. Sediment eroded and...bachelor thesis 2017

Boeser, D.M. (author)Clean drinking water is essential for life. In Bangladesh and the northern part of India however, around the 30 and 40 million people are estimated to be exposed to Arsenic in drinking water at concentrations above the 0.05 mg/L. Studies show that the aquifers of Holocene age near the Ganga River are polluted. These aquifers are between the 10...bachelor thesis 2011

Kartika Surjosantoso, M. (author)The objective of this thesis is to investigate experimentally the impact of gas phase reactions during a simple ISC process especially the role of heat and oxygen presence in the system. Heat plays an important role in both air and nitrogen injection experiments because the injected gas needs to be heated first to the set temperature before...master thesis 2012

Velema, W.R. (author)Raw magnesium chloride can be recovered using solution mining at a depth of a 1500 to 2000 meters. Underground caverns are formed in stacked layers of bischofite , carnallite and halite. The salt layers consist for a large part of NaCl and but contain a minimum of at least 35% magnesium chloride. Recovery is implemented by injection of fresh...master thesis 2010

Den Ouden, L. (author)Low salinity water flooding (LSF) has been proved to be a promising enhanced oil recovery method for sandstone reservoirs. The efficiency of LSF in carbonate reservoirs has not been proven completely yet, because there are still uncertainties about the LSF recovery mechanism in carbonate. From experimental studies, it was shown that wettability...master thesis 2014

Toutouh, Azeddine (author)In 1949, Toms (Toms B.A., (1949, 1977)) observed that small amounts of a drag reducing agent (DRA) could cause a considerable drag reduction in turbulent pipe flow. In application of polymer enhanced oil recovery, degradation of polymers in the supply lead could cause clogging. It was, however observed that surfactants at sufficiently high...master thesis 2018

Queroga Caldas, Luiza (author)Salt caverns formed by solution mining may cause soil subsidence, because the surrounding adapts to fill the void (cavity) created in the strata. The cavern volume is hence not only a function of salt extraction (estimated from mass balance) but also a function of salt creep. The cavern size can be measured by sonar, but a less costly way would...master thesis 2018

Hassan, A.M. (author)Characterization of fluid properties is significant in the petroleum engineering practice, especially in solvent-based enhanced oil recovery (SEOR) where the use of injected chemicals should ideally be reduced to the bare minimum in order to minimize the costs and environmental impact of SEOR. However, current techniques for measurement inside...master thesis 2015

Lourma, S. (author)Arsenic contamination of the groundwater and as a consequence, of the drinking water, has developed to a major problem for many regions globally during the last decades (Chile, China, United States, Argentina, and Mexico). The issue of Arsenic contamination has already been studied extensively in West Bengal, India and Bangladesh, which are some...master thesis 2011

Den Boer, C.A. (author)We investigate non-isothermal compositional flow in methane-rich geothermal aquifers by coupling a thermodynamic model and a dynamic flow model. For the thermodynamic model, we develop a MATLAB program, which calculates the thermodynamic equilibrium of the H2OCH4-NaCl mixtures at high pressure conditions and reservoir temperatures. In the same...master thesis 2012

Broens, M.M.J. (author)The formation of microemulsions of an EOR surfactant with n-decane was studied in a microfluidic setup using fluorescence microscopy. Generally microemulsions are studied under static conditions by means of phase behavior tests. However, oil mobilization fromreservoirs is a dynamic process and therefore it is important to understand how...master thesis 2015

De Mooij, J.W.C. (author)At the moment global climate change is one of the most prominent environmental and energy issues of our life time. Currently CO2 levels in the atmosphere stand at 387 ppm, almost 40% higher since the start of the industrial revolution and the highest for at least the last 650,000 years. About 96% of these carbon emissions are the result of using...master thesis 2010

Loerakker, M. (author)For a long time gas hydrates were considered to be a hindrance for the natural gas and oil industry. However, since natural gas hydrates deposits were discovered in 1967 the conception of natural gas hydrates as an important energy resource is well accepted. Latest estimations indicate that the amount of natural gas stored in hydrate form is...master thesis 2013

Zholdybayeva, A. (author)Oil recovery in fractured reservoirs by water flooding critically depends on the wetting properties of the matrix blocks between the fractures. The recovery from oil-wet reservoirs is almost negligible. In incompletely oil-wet systems, the presence of initial water may change the wettability characteristics so that very slow imbibition and some...master thesis 2012

Gilding, D.T. (author)Geothermal energy is hot and sustainable. A recent run for licences has sparked questions on the optimisation and recovery of geothermal energy from the subsurface of the Netherlands through optimal project placement. The effect of heterogeneities on interference of geothermal projects in the West Netherlands Basin and the target Early...master thesis 2010

Peksa, A.E. (author)Satisfying continuously growing world energy demand by use of fossil fuels has increased carbon dioxide (CO2) concentration in the atmosphere. Dramatically higher concentration of the CO2 has a negative environmental impact, for that reason a need for analyzing possible mitigation options has arisen. The research framework on the mitigation...master thesis 2010
