Polymer flooding is widely used due to its advantages. The method is well suited for oil recovery at various stages of field development with uneven permeability, different reservoir properties and structure; it is carried out at low reagent flow rates and does not require expensive and complex equipment. The disadvantages of the method, such as decreased stability of poly-mer solutions at high temperatures (thermal destruction) and mineralization of formation fluids, are usually eliminated by careful selection of polymer composition. The article considers the efficiency of polymer flooding technology to determine the de-gree of properties of the reagents used. For this purpose, the reagents were determined, which should be carried out taking into account individual features and the state of development of a particular field. Studies were conducted to determine the dependence of viscosity on polymer concentra-tion, and the viscosity of the polymer solutions were determined for one day. The study found that the iron concentration in the water is below 1 ppm, which is acceptable that oxygen is not present in the water.
