... of SAS in this research is to displace a continuous oil phase with low-IFT displacement fronts with mobility control by polymer. Previous research found that 2-ethylhexanol-7PO-15EO (2-EH-7PO-15EO, or "7-15") as SAS was able to reduce the IFT between polymer solution and the reservoir oil from 15.8 mN/m...

... was compared to that of the water-flood baseline. Our observations showed that prolonged injection of polymer solutions could clog pore-throats of sizes larger than the measured mean polymer-coil size, which is consistent with lab and field observations. This finding highlights a major limitation in some...

... and pumping unit. Polymer solution properties such as concentration, viscosity, and filter ratio, have been closely monitored and adjusted as necessary. Operational procedures have been improved to ensure adequate injectivity and polymer propagation through the formation. Oil and water production is tested...

... as the degree of hydrolysis increases. Consequently, the fractional number of a carboxylic group within a polymer structure is directly proportional to the degree of hydrolysis and viscosity of polymer solution. This effect is more prominent with the increase of temperature, as the degree of hydrolysis...
