At the present moment there is no single opinion about the effectiveness of barrier water-flooding implementation on gas and oil deposits. This article analyzes the implementation of the mentioned measure at the D2arIVb object of Vostochno-Suslovskoe field, Saratov region. It is revealed that barrier water-flooding allowed neither preventing gas breaching into the oil well nor stabilizing reservoir pressure at the selection areas. While simultaneous withdrawal of oil and gas, in spite of large amount of the pumped water, one can observe oil migration into the gas-saturated layers of the reservoir. According to the analysis some measures are Recommendations on additional extraction of oil residual reserves, based on data analysis, are presented.
Key words: barrier water-flooding; effectiveness; gas and oil deposits; additional extraction of oil residual reserves.

At the moment there is an acute problem of increasing the residual oil production without harming the environment. To address the global challenges of the recovery of the remaining oil reserves at the fields at the late stage of development, ecologically safe method using anionic surfactant based on sodium salts of fatty acids is suggested. The present paper considers the influence of the pumping rate of the proposed surfactant on the phase permeability of hydrophobic petro-physical model of a reservoir and further extraction of residual oil. It is shown that slowing of the reagent injection rate brings increase of the permeability of water and enhances oil recovery factor.
Key words: petro-physical reservoir model; surfactant; pore volume; permeability.

The paper says that at the late stages of development there appears the necessity of unloading the systems of wells products’ collection, preparation, transportation and maintenance of formation pressure (MFP). The ways of solving the problem at the level of strategy development within the frames of the system of collection, preparation, maintenance of formation pressure at cluster sites are identified. Some method of water cutting-off and treatment at cluster wells, followed by its pumping into injection wells of the same sites by means of introducing pipe water separators is proposed. The criteria of the proposed method applicability are revealed.
Key words: system of wells products’ collection, preparation and transportation; system of maintenance of formation pressure (MFP); cluster sites; pipe water separators.

During operation of glycol systems operators often come across the problems caused by organic sediments accumulation. The main components of these sediments are polymers with structure similar to polyethylene glycol. The article describes standard problems, caused by sediments formation in glycol systems. Practice of laboratory testing of various reagents used for washing of glycol systems and sediments removal is presented. During testing the best washing properties were demonstrated by mono- and polyamine-based water solution, which was recommended for use. The practice of the solution use to remove sediments from the system of technological heating of oil and gas platform is described as well. The main conditions under which the washing was conducted are discussed. It was found out that sediments were completely removed from the areas with high linear flow velocity of the washing solution. At the areas here linear flow rate of washing solution was minimal, for example, in the expansion vessel, the sediments were not completely removed. Recommendations on planning of works related to sediments removal, based on field experience, are submitted. It is shown that after washing the system of technological heating of offshore oil- and gas-producing platform its productivity was restored.
Key words: triethylene glycol; sediments; glycol systems; polyethylene glycol; polyamines.
