In the recent years, the estimation of conditions and development prospects of oil industry shows the depletion of major oilfields previously brought into production and reduction of reserves increment volumes at the oilfields with complex geological settings.

In this connection, a special attention is paid to the application of new oil production technologies that allow to significantly increase oil recovery of reservoirs where conventional recovery techniques fail.

One of the chemicals that is actively applied during enhanced oil recovery (EOR) operations is polyacrylamide (PAA), an artificial water soluble polymer.

The range of technologies using the PAA includes injection of gelled into formation, creation of polymerthickener banks in the formation, as well as creation of sediment-gelling agent banks.
