Bos, Martijn (author)Non-Newtonian foam flow in a reservoir can be modeled numerically by discretization of the corresponding analytical formulas. The injection of foam is compared to the injection of water by comparing the injection pressures, which is represented as a dimensionless pressure rise at the injection well. The model first applies the forward-difference...bachelor thesis 2017

Busch, S.P. (author)The partitioning inter-well tracer test (PITT) is a method to determine average oil saturation between an injector-producer pair. Tracer tests can be used to quantify incremental oil recovery in enhanced oil recovery (EOR) pilots and for reservoir surveillance purposes. This study provides a sensitivity analysis of the inter-well tracer test,...master thesis 2016

Toutouh, Azeddine (author)Oil is one of the major contributors to energy consumption. Oil reserves are expressed as the total amount of economically and technically producible oil. Total oil consumption is increasing (per capita it remains more or less the same) but it has no unambiguous influence on the remaining reserves due to new discoveries. However, increasingly...bachelor thesis 2016

Jones, S.A. (author), Laskaris, G. (author), Vincent-Bonnieu, S.Y.F. (author), Farajzadeh, R. (author), Rossen, W.R. (author)We present a comparative study of foam coreflood experiments with various surfactant concentrations. Plots of apparent viscosity vs. injected gas fraction were obtained for surfactant concentrations at the critical micelle concentration and above. Bulk foam stability was measured for all concentrations and compared with the coreflood results....journal article 2016

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

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

Ansari, M.N. (author)Enhance Oil Recovery (EOR) techniques are theoretically very promising but in real life suffer the effects of many physical complications in the subsurface which are yet to be understood in detail. One such complication is the detrimental effect of oil in foam in foam EOR. Current-generation reservoir simulators represent these effects in an...master thesis 2015

Heins, R. (author)Enhanced oil recovery by gas injection can show excellent displacement efficiency but may suffer from poor sweep efficiency. A promising method to overcome poor sweep efficiency in gas-injection enhanced oil recovery processes is foam injection. The effect of oil saturation on foam stability is complicated and not fully understood. Complexity in...master thesis 2015

Koops, M. (author)Foam is a promising means of increasing sweep efficiency in enhanced oil recovery processes where gas is injected into a reservoir. However, the effectiveness of foam is hard to predict due to its complex behavior. Therefore accurate modeling is important to effectively predict field performance. This requires correct foam parameters in...bachelor thesis 2015

Ameri, A. (author)In the phase of declining oilfields and at a time when recovering hydrocarbons has becoming more difficult, effective techniques are the key to extract more oil from mature fields. The difficulty of developing effective techniques is often the real obstacle when dealing with heterogeneous formations such as naturally fractured reservoirs, which...doctoral thesis 2014

Chahardowli, M. (author), Bruining, J. (author)Mutually-soluble solvents can enhance oil recovery both in mixed-wet fractured reservoirs. When a partially waterwet matrix is surrounded by an immiscible wetting phase in the fracture, spontaneous imbibition is the most important production mechanism. Initially, the solvent moves with the imbibing brine into the core. However, upon contact with...conference paper 2014

Van der Meer, J.M. (author), Van Odyck, D.E.A. (author), Wirnsberger, P. (author), Jansen, J.D. (author)If secondary hydrocarbon recovery methods fail because of the occurrence of gravity override or viscous fingering one can turn to an enhanced oil recovery method like the injection of foam. The generation of foam can be described by a set of partial differential equations with strongly nonlinear functions, which impose challenges for the...conference paper 2014

(author)We apply adjoint-based optimization to a Surfactant-Alternating-Gas foam process using a linear foam model introducing gradual changes in gas mobility and a nonlinear foam model giving abrupt changes in gas mobility as function of oil and water saturations and surfactant concentration. For the linear foam model, the objective function is a...journal article 2014

Dharma, A.S. (author)In gas-injection enhanced oil recovery (EOR), foam is a promising method to improve sweep. We studied foam for EOR through analytical modeling and simulations in two cases: the ability of foam to prevent gravity override over large distances and the effect of oil on foam processes. Shan and Rossen (2004) present a simple model for SAG ...master thesis 2013

Simjoo, M. (author)Growing worldwide oil demand increased the need of new and efficient oil recovery methods. Gas injection in oil reservoirs is deemed one of the most widely used methods to increase oil recovery. However, the full potential of gas injection is often not realized due to poor vertical and areal sweep efficiency of the gas. Foaming could be a...doctoral thesis 2012

Ashoori, E. (author), Marchesin, D. (author), Rossen, W.R. (author)The use of foam for mobility control is a promising mean to improve sweep efficiency in EOR. Experimental studies discovered that foam exhibits three different states (weak foam, intermediate foam, and strong foam). The intermediate-foam state is found to be unstable in the lab whereas the weak- and strong-foam states are stable. The model of...journal article 2011

Namdar Zanganeh, M. (author)Chemical enhanced oil recovery (EOR) is relatively expensive due to the high cost of the injected chemicals such as surfactants. Excessive use of these chemicals leads to processes that are not economically feasible. Therefore, optimizing the volume of these injected chemicals is of extreme importance. We intend to maximize the long-term...doctoral thesis 2011
