Nazarbayev University School of Mining and Geosciences.http://nur.nu.edu.kz/handle/123456789/5410In the context of the ending lifetime of the fields and unstable oil prices, Enhanced Oil Recovery (EOR) methods are particularly relevant. After primary recovery, waterflooding is the most common and economical practice to improve the oil recovery factor. At the current time, around 35% of the global average oil recovery factor is associated with waterflooding. However, the heterogeneity of formations and a great distinction between water and oil viscosities lead to fingering of the injected water leaving a large amount of oil untouched in the reservoir. According to estimation studies, around 7000 billion barrels of crude oil are remaining as residual oil after the secondary recovery phase....enAttribution-NonCommercial-ShareAlike 3.0 United StatesEmbargoenhanced oil recovery methodMaster's thesis
