“…If the injection pressure of the polymer solution is less than the formation parting pressure and is not so high that it requires expensive pumping equipment, then the reservoir pressure is not critical [55]. The porosity of the reservoir rock must be medium to high (higher than 18%) to assure a good storage capacity [84]. The acceptable range of the absolute permeability of the reservoir rock is between 50 and 250 md [64].…”

Polymer flooding is an enhanced oil recovery (EOR) method used to increase oil recovery from oil reservoirs beyond primary and secondary recovery. Although it is one of the most well-established methods of EOR, there are still continuous new developments and evaluations for this method. This is mainly attributed to the diverse polymers used, expansion of this method in terms of application, and the increase in knowledge pertaining to the topic due to the increase in laboratory testing and field applications. In this research, we perform a review of the factors impacting polymer flooding in both laboratory studies and field-based applications in order to create guidelines with respect to the parameters that should be included when designing a polymer flooding study or application. The main mechanism of polymer flooding is initially discussed, along with the types of polymers that can be used in polymer flooding. We then discuss the most prominent parameters that should be included when designing a polymer flooding project and, based on previous laboratory studies and field projects, discuss how these parameters impact the polymer itself and the flooding process. This research can provide guidelines for researchers and engineers for future polymer flooding research or field applications.

East-Messoyakhskoye is a giant oil green field, unique in terms of oil reserves, located in arctic conditions. The main distinctive field characteristic is viscous oil in the cold, unconsolidated reservoir. Understanding all the challenges of developing such reservoirs, a proactive study of polymer flooding began at an early field development stage. A lot of study and research has been done, including the full range of necessary elements. This paper summurises the first pilot project results, gained experience and achievements that allowed us to successfully implement the pilot project, confirm the prospects of polymer flooding technology and lay the foundation for further work.

The paper describes the basic features of the East-Messoyahskoe oil field that are important for efficient reservoir development, the key of which are high oil viscosity (111 cP), high heterogenieity and permeability contrast, and the presence of aquifer with a different strength. The review of the experience in proactive breakthrough risks identification is presented. The actual breakthroughs during waterflooding of the PK-13 reservoir of the East-Messoyahskoe oil field are described and analyzed. The backgrounds and regularities increasing the risks of breakthroughs are identified. The analytical calculations have been made and key influencing factors have been defined. Based on the obtained results, the methodology of the proactive breakthrough identification was developed. The methodology has been tested in the real conditions of the East-Messoyahskoe oil field. The first results have been received, which confirm the operational efficiency of the developed methodological approach. All wells were rated according to their breakthrough risk, and measures for operative and proactive breakthroughs risk management has been proposed. All listed are combined into a system which permits minimization of breakthrough risks and manages them for the increase of unconsolidated heavy oil reservoirs development efficiency.
