... molecular weight polymers showed the highest EOR effect. Current study is of great significance for the synthesis of amphiphilic polymer and oil field applications. A polymer system with proper molecular weight distribution and grafting density can effectively improve oil recovery for a polymer flooding...

... Abstract Polymer flooding has been widely applied through past decades to increase oil recovery after waterflood. Water-soluble polymers are used to increase the viscosity of injected water that is a requirement for better sweep efficiency, but accelerated production due to polymer flooding may...

... Abstract Remaining oil after polymer flooding is very scattered, and the remaining oil in top sections is extremely difficult to develop, yet there is no prevailing technology suitable for developing the reservoirs after polymer flooding. Gas injection for stable gravity combination flooding...

... Polymer flooding reduced mobility ratio as compared to conventional water flooding, making it easier for oil displacement, thereby improving the volumertric sweep efficiency. To avoid a sharp viscosity contrast with the chase water, generally large slugs of polymers with viscositites tapered...

... Abstract Polymer flooding is one of the most commonly used techniques to improve oil recovery; however its application is dependent on the technical and economic feasibility along with the knowledge of the risks involved. The presented work is focused on quantifying the uncertainties affecting...

... Abstract Polymer flooding has been widely applied in China and can enhance oil recovery by more than 10%. However, there is about 50% remaining oil in reservoirs. Therefore, it is important to develop a new technology which based on the mechanism of both lowering interfacial tension to an ultra...

... Abstract Polymer flooding is one of the most mature enhanced oil recovery (EOR) methods with many field implementations including those in China, Germany, Oman, and USA. The primary role of polymer is increasing the injected water viscosity, hence reducing the displacing front mobility...

... Abstract As heavy oil resources are making an ever-increasing contribution to the energy supply of the world, maximizing recovery from these wreservoirs has attracted significant attention in recent years. Leveraging low salinity waterflooding and polymer flooding to improve heavy oil recovery...

... Abstract The application of Enhanced Oil Recovery (EOR) techniques is encouraged by the growing demand for oil. Optimizing oil production from current resources is becoming the main strategy for many oil producing companies around the world. Among EOR processes, polymer flooding...
