The paper was devoted to identifying the strengths and weaknesses of demulsifiers widely used in PJSC "TatneftIt was carried the analysis of their impact on oil and wasstudied of their properties under the influence of various factors such as concentration, temperature, time, and their influence on the degree of efficiency demulsification. The comparison of the basic properties and summing up the final results of the work of the studied reagents were determined.
Materials and methods
Research on the effectiveness of demulsifiers, such as Rekod-118 A2/3, Intex-720 andthe Reapon-IK-2M was carried out on the emulsions sampled wells in the Devonian and Carboniferous type JSC "Tatneft" method "bottle test".
Studies revealed the most effectiveness of reagent Reapon-IK-2M in the process of thermochemical dehydration of Devonianoil of PJSC "Tatneft" several oil fields.
It was proven necessity and the validity of certain approaches to obtain more reliable information on the effectiveness of comparable reagents of demulsifiers are widely used in PJSC "Tatneft".
