The development of oil and gas wells is a whole range of works aimed at the production of hydrocarbons from fields to the bottom of wells. At the same time, a certain order of work or a certain form of organization of the extraction of natural resources should be provided. At present, the need to use hydrogeological data to solve a number of problems that arise during the exploration of gas and oil fields in Eastern Siberia. As you know, the east-ern part of Yakutia has a huge resource potential. The area under consideration has a number of features, the main of which are the presence of a cryolithozone and abnormally low reservoir pressures (ANPD) in some intervals of the section, which is not "good" for reservoir pressure, and also affects the reduction of efficiency and development. The most popular method of developing oil fields is the method of Reservoir Flooding. This method makes it possible to maintain high current flow rates of oil wells, and as a re-sult, to achieve a high percentage of recoverable oil reserves. And in this work, we will consider suitable options for the development of wells – flooding methods, which are suit-able for the above features on the territory of Eastern Yakutia.

In order to prevent the formation of water and gas cones in the zones of water-oil and gas-oil contact, water-polymer flooding is being introduced into the Yakutia oil fields. Might have an impact on the oil displacement coefficient rising. The emulsion was obtained mechanically and stirred using paddle mixers from 26 sec to 20 min.We drew two circles the inner 2 cm and the outer 6 cm. The emulsion was placed in a tube, then it was lifted and a stopwatch was turned on. Turned off only when the emulsion went beyond the outer circle. Emulsions become less stable when their formation time increases. As a result, the most stable emulsions are made from an oil mixture with a PEG solution, while the least stable emulsions are made from Na-CMC solutions.
