Polymer enhanced oil recovery
WebApr 20, 2008 · Abstract. A number of commercially available polymers have been tested for enhanced oil recovery based upon viscosity, filterability, and surfactant compatibility, and chemical and thermal stability testing has been carried out with some of these as well. Several high molecular weight polymers exhibited high viscosities at salinities up to … WebEnhanced oil recovery (EOR), also known as tertiary recovery, is used to further produce oil after the primary and secondary phases of reservoir production. According to the US Department of Energy, enhanced oil recovery can extract 40-60% of the original oil in place, which is a substantial improvement over the 10% from primary recovery and 20-40% in …
Polymer enhanced oil recovery
Did you know?
WebEnhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, carbon dioxide and water are injected along … WebMay 13, 2024 · Additionally, polymer gels, polymer-enhanced foams, and foamed gels have also been used to improve oil recovery by plugging the high-permeability thief zones …
Web1 day ago · The gel blocks the high-permeability layer, forcing the flooding liquid to flow through the low-permeability layer, thus enhancing the oil recovery rate. Polymer gel is another widely studied category of plugging agents, but its strength is relatively low. WebUncontrolled flow through different permeability zones in oil reservoirs remains a huge challenge during water flooding, which can significantly limit microbial-enhanced oil …
