The use of RFID technology to measure dielectric coefficients of diethyl ether-oil-brine mixtures for enhanced imbibition experiments.

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...

Foam Stability in Presence of Oil: A Simulation and Experimental Study

This thesis investigates bulk foam stability in absence of oil, and in presence of oil (hexadecane). Foam in absence of oil was produced by sparging nitrogen at a fixed flow rate through the surfactant solution. Foam in presence of oil was produced by stirring a mixture of surfactant and oil with an immersion mixer. The behavior of foam in...

Injectivity errors in foam EOR

Simulators play a crucial role in EOR reservoir modeling. One of the big problems with the simulation of gas injection in SAG foam processes, is that foam collapse near the injection well is poorly represented in the simulator well model. This paper focusses on the question whether a simulator using the Peaceman equation for a homogeneous...

Simulation of Geochemical Processes during Low Salinity Water Flooding by Coupling Multiphase Buckley-Leverett Flow to the Geochemical Package PHREEQC

Simulations carried out for low salinity water flooding often do not include geochemical processes. Salt concentration, and thus the salinity, is modelled as a water tracer that does not react with the reservoir formation. The goal of this MSc thesis is to improve the understanding of the influence of geochemical processes on the mixing of...

Sand Erosion in Cold Heavy Oil Production with Sand

Cold Heavy Oil Production with Sand (CHOPS) is a production method to produce heavy oil (>100 cP). It is mainly applied onshore Canada in unconsolidated sand reservoirs. Different theories exist about how the erosion process takes place inside the reservoir. This research project focused on the influence of the grain stress on the sand erosion...
