Electrokinetics in Low Salinity Waterflooding

Low salinity waterflooding (LSF) is a promising improved oil recovery (IOR) technique. The enhanced composition of injected water in LSF can change the wettability of the formation from oil-wet/ mixed-wet towards a more water-wet state. This leads to improved relative oil permeability (kro). The zeta potential, which is the electric potential at...

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...

Physical Aspects in Upscaling of Fractured Reservoirs and Improved Oil Recovery Prediction

This thesis is concerned with upscaled models for waterflooded naturally fractured reservoirs (NFRs). Naturally fractured petroleum reservoirs provide over 20% of the world’s oil reserves and production. From the fluid-flow point of view, a fractured reservoir is defined as a reservoir in which a number of naturally occurring fractures have a...
