Polymer Flooding for Enhanced Oil Recovery
Polymer flooding has been used for more than 40 years to effectively recover the remaining oil from the reservoir, up to 30% of the original oil in place. Due to decreased water production and enhanced oil production, the total cost of using the polymer …
Polymer flooding: Current status and future directions
2023年4月1日 · Polymer flooding is an enhanced oil recovery (EOR) method that utilizes high molecular weight (Mw) polymers to increase viscosity of injected water (i.e., reduce water mobility)—thereby improving reservoir sweep efficiency when displacing viscous oil.
Polymer Flooding - an overview | ScienceDirect Topics
Polymer flooding (Polymer augmented waterflooding) is waterflooding in which organic polymers are injected with the water to improve horizontal and vertical sweep efficiency. The process is conceptually simple and inexpensive, and its commercial use is increasing despite relatively small potential incremental oil production.

2016年10月19日 · Polymer flooding consists of injecting polymer-augmented water into a subterranean oil formation in order to improve the sweep efficiency in the reservoir. The increased viscosity of the water causes a better mobility control between the injected water and the hydrocarbons within the reservoir.
Review on chemical enhanced oil recovery using polymer flooding ...
2020年6月1日 · Polymer flooding as a chemical EOR method involves adding polymer molecules in order to increase water viscosity. Increasing water viscosity will improve the mobility ratio of injected fluid to reservoir fluid toward a more favorable value.
The Science of Polymer Flooding - Polymer Technologist
2024年11月5日 · Polymer flooding is an enhanced oil recovery (EOR) technique aimed at increasing the extraction of oil from reservoirs that have already undergone primary and secondary recovery methods. This process involves injecting a polymer solution into the reservoir to improve the mobility of oil, making it easier to extract.
Modeling and Simulation of Polymer Flooding with Time-Varying …
Polymer flooding is one of the most incipient chemical-based enhanced oil recovery process that utilizes the injection of polymer solutions into oil reservoirs.
Polymer floods use polymer solutions. Gels add a crosslinker to the polymer solution. The “Windfall Profits Act of 1980” encouraged grouping the two methods together as “polymer augmented waterfloods”. The Oil and Gas Journal does not distinguish the two methods in their biannual EOR survey. What is the difference?
Opera-fl tional improvements are described to minimize mechanical and oxidative stability to allow HPAM polymers to be viable to 70 C and ATBS polymers to 120 C. Key factors affecting polymer retention are summarized. The paper points out unresolved issues and future directions for polymer ooding. fl 2023 The Authors.
