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...

Model for gas sweep with foam

In this BSc-thesis a Surfactant-Alternating-Gas (SAG) foam displacement is represented by an idealized model. Shan and Rossen show in the article ‘Optimal Injection Strategies for Foam IOR’ (2004) that this model, though greatly simplified, is a useful representation of a foam displacement in the physical world, where pressure gradient is the...
