CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of priority to an Iran patent application having serial number 139450140003003488 filed on Jun. 22, 2015, which is incorporated by reference herein in its entirety.TECHNICAL FIELD
[0002] The present disclosure relates generally to oil extraction and, more particularly, to polymer flooding processes for oil recovery. Also it relates to other applications such as cosmetics, coatings and drilling fluids.BACKGROUND
[0003] In the context of oil extraction, oil reservoirs can be fractured, thereby trapping oil even upon completion of classical oil recovery processes, such as water flooding, gas injection and in-situ combustion. There are known processes, sometimes referred to as “secondary” and “tertiary” oil recovery, aimed at recovering portions of this trapped oil. One such process is polymer flooding. This is a flooding process that uses natural polymers, such as xanthan and starch, and synthetic polymers, for...
