The article deals with the issues of improving the quality of highly watered well production fluid processing using chemical demulsifier reactants at crude oil processing facilities; the analysis of the use of the reactants at the Samotlor field has been made. The article presents the results of the study of the effectiveness of the "Hercules 2202 grade A" and "SNPH-4460-2" demulsifiers in comparison with the indicators of oil and bottom water processing achieved in the presence of the reactants used at existing facilities; their optimal consumption has been determined. The study has shown that the selected demulsifiers provide the required quality of the oil and water under processing at the considered oil processing facilities and can be used along with the basic reactants for these facilities. On the basis of total indicators, the best results have been achieved using "Hercules 2202 grade A" with the improved indicators of water cut and residual oil content in water by 33.9 % and 2.8 % while reducing the reactant consumption by 9.7 % compared to the basic demulsifier.

The paper shows the role of and the outlooks for the extension of Naftoport Oil Terminal in Gdańsk, Poland as well as the impact of the ongoing development on oil import options and, as a result, on the oil security of the country. The expansion of the oil terminal in Gdańsk is an extremely important project and the largest investment of this type in Poland. Key elements of the development of the terminal are: new transshipment stations and their enhancement, new oil tanks, the construction of the second oil pipeline running to the center of Poland, the development of crude oil technological installations, electricity grid, water and foam networks, sanitary networks, roads, and automation systems. The expansion of Naftoport significantly increases Poland’s oil security as well as import capabilities of the country, ensuring continuous oil supplies to Polish refineries, often at a lower price.

Large steel crude oil tanks constructed in soft foundations are susceptible to various types of settlement deflections. The most common type is planar inclined foundation. In this paper, the FEM is used for the study of deformation characteristic and stress distribution of large steel crude oil tank under the planar inclined foundation approaching to critical value. Results show that deformation characteristic of tank is unevenness; max stress in tank shell occurs in middle-low part of floating roof tank; the ultimate value of large steel crude oil tank under the planar inclined foundation is 0.89m.
