Abstract: Comparative experience of using various fluids in the processes of well con-struction and repairs, formation drilling and killing a well, as well as intensification of oil production and enhanced oil recovery, shows high efficiency of emulsion compositions. At final stage of oil fields development these compounds find a wide application in various enhanced oil recovery technologies.
Synthesis of surfactants which are emulsifiers component of direct and invert emulsions was carried out by sulfonation of technical fish oil (waste from the fish processing industry) with specific fraction composition of fatty acids. The possi-bility of using the obtained emulsifier as an emulsion composition component for enhanced oil recovery is shown and application efficiency is estimated
