Maas, T.R. (author)• In the planning of new wells, typically the same trajectory is used for conventional wells and wells with smart completions. This study demonstrates that the economically optimized trajectory for smart and conventional wells can be very different. Two new well trajectory optimization algorithms were developed using Stochastic Pattern Search ...master thesis 2016

Laskaris, G. (author)Foams find many applications in the oil industry with their uses ranging from fracturing stimulation treatments to enhanced oil recovery processes. Many of these applications concern the reduction of injected gas mobility which can be induced by a strong foam. However, foam behavior inside a porous medium is complex and a fully predictive model...master thesis 2015

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

Primarini, M.I.W. (author)The rapidly decreasing reserves of conventional gas has forced oil and gas industries to conduct more exploration on unconventional resources, like shale gas. To produce gas from shales in economically viable manner, stimulation techniques like hydraulic fracturing are required. One important factor for a successful hydraulic fracturing is...master thesis 2015

Van El, W.A. (author)“Dispersion” has two meanings in reservoir engineering: (1) the variety of arrival times at a production well for an injected tracer, which is mostly a function of heterogeneity of permeability in the reservoir, and (2) mixing of injected fluids in situ. It is very difficult to distinguish these two processes in situ, while the success of...master thesis 2015

Saleh, K. (author)One of the major problems associated with oil and gas production is the large volume of produced water. Operators around the world are facing significant costs with the treatment and disposal of produced water. Downhole separation, a relatively new technique, has been developed to reduce the costs of produced water and increase oil production....master thesis 2015

Purba, R.T. (author)This thesis addresses the problem of permeability estimation of an oil reservoir using oil production data, a process known in the oil industry as computer-assisted history matching or data assimilation. Zilko (2012) compared the well-known Ensemble Kalman Filter method for data assimilation with the Non-Parametric Bayesian Beliefs Network (NPBN...master thesis 2015

Kooijman, D.A. (author)The primary gas reservoirs in the Southern Dutch offshore are in decline. Discoveries of new gas reservoirs are getting smaller and smaller reservoirs receive more attention. The three major carbonate beds in the Basal Zechstein (Z1C, Z2C and Z3C) are considered potential secondary gas reservoirs. To be able to develop the gas from these...master thesis 2011

Noordoven, Q.A.L.V. (author)This research focuses on the stimulation of shale gas plays of Jurassic Geverik member and Carboniferous Altena formations in the Dutch subsurface. The production of shale gas involves stimulation of the formation by hydraulic fracture treatment. Two typical types of stimulation are used in the industry. The viscous fluid treatment, which...master thesis 2011

Liuzzi, D.V. (author)From 3D seismic interpretation and well logs five of the strongest reflectors of the Upper Jurassic Source Rock along the Southern DGC were mapped, the markers were correlated with biostratigraphic and geochemical data. It was generated a simple 3D basin model. The Southern DCG experienced a strong subsidence during Kimmeridgian with tilted...master thesis 2011

Ruoff, M.C. (author)In this work we developed a numerical model for channel flow on a pore or micro scale. A straight channel was simulated with a flow regime of Re=0.03 and Re=0.3 (comparable to typical fluid flow in petroleum reservoirs) to visualize the characteristics of flow and dispersion up to the Fickian limit. The objective of this study was to quantify...master thesis 2011

Kahrobaei, S. (author)Solvent injection has been considered as an efficient method for enhancing oil recovery from fractured reservoirs. If the mass transfer would be solely based on diffusion, oil recovery would be unacceptably slow. The success of this method therefore depends on the degree of enhancement of the mass exchange rate between the solvent residing in...master thesis 2011

Brueren, T.L.J. (author)A screening study and subsequent dynamic simulation of selected Enhanced Oil Recovery (EOR) methods for the Rijn oil field are presented. The objective of the study was to obtain insight in the EOR potential of the Rijn field. The Rijn oil field, located in block P15 in the Dutch sector of the North Sea Continental Shelf, produced 24MMSTB oil...master thesis 2011

Ubbink, B.J. (author)The purpose of this study is to gather information about the gas hydrate formation when an equimolar gas mixture of CO2 and CH4 is injected on top of a liquid aqueous phase at 275.85 K and various pressures ranging between 2.5 and 6.0 MPa . With these experiments it can be determined if there is preferred gas hydrate formation with CO2 or CH4....bachelor thesis 2011

Persoon, R.L.M. (author)The Amstel oil field is located in block Q13a in the Dutch southern North Sea about 13 km off the coast of Scheveningen. The oil is trapped in an Early Cretaceous reservoir which is informally named Amstel Sandstone. At present, the production license of the field is held by Gaz de France Suez, TAQA Energy has a 10% share. The Amstel field is...master thesis 2011

Steffens, A.J.E. (author)Carbonated Water Flooding (CWF) is an enhanced oil recovery (EOR) method where an oil reservoir is flooded with water containing dissolved CO2. It is being considered as a promising EOR (Enhanced Oil Recovery) method for maturing light and heavy oil fields. A numerical and experimental study of the CWF was conducted, focusing on the underlying...master thesis 2010

Oragui, O.C. (author)Gas hydrates are significant resource of natural gas existing both on-shore buried under the permafrost and off-shore buried under oceanic and deep lake sediments. Earlier studies have demonstrated that large volumes of gas can be produced from gas hydrate accumulations by means of depressurization-induced dissociation using vertical wells. In...master thesis 2010

Janzen, M.R. (author)The idea of this thesis is to use the technique for applications in petroleum engineering. This has been previously thought about, and the biogrouting technique has already been verified in the laboratory to work in a well (much larger pressure and temperature) (Latil e.a. 2008). The purpose of this thesis is to examine if the technique can be...bachelor thesis 2010
