http://www.ogbus.ru/authors/Garaev/Garaev_1.pdf (in Russian)
Flowlines pumping aggressive chemicals, which cause intense corrosion damage the inner surface of pipelines. The aim of the work is to study the corrosion metal-base laminate field pipelines and determining their causes. Based on the results of studies of aggressiveness of the pumped medium and the metal field pipelines shown that single-tion of the causes of their destruction is cracking. Realization of laboratory studies showed that the most probable cause of cracking is hydrogen produced during its operation of the tread.

The given equations are necessary for calculation of oil losses from evaporation. The new criteria equations have been compared with earlier existing criteria equations, which disadvantages have been eliminated during reception of new dependences. Possible errors rate of the received formulas is calculated.

THE EXPERIMENTAL STUDY OF THE INFLUENCE OF THE LOW FORMATION TEMPERATURE AND HIGHLY MINERALIZED FORMATION FLUIDS OF THE IRELYAKH GOF ON THE EFFECIENCE OF THE DISPLACEMENT AGENTS OF THE MINERAL AND POLYMER NATURE
http://www.ogbus.ru/authors/PortnyaginAS/PortnyaginAS_1.pdf (in Russian)
The results of the investigations show that filtration-capacitive properties of the reservoir decrease at the use of a highly mineralized agent for maintaining the reservoir pressure. Experimental studies reveal that solutions on the carboxymethylcellulose base have a larger stability of properties at oil displacement in comparison with the solutions on the surface-active agent base. The carboxymethylcellulose solution with the concentration of 5 g/l is characterized by the highest value of oil recovery ratio (68%). Thus it can be recommended as a basic displacement solution for reservoir pressure maintenance and for increasing the oil recovery ratio on the Irelyakh field.
Keywords: gas and oil field, reservoir pressure maintenance, oil displacement agent, formation water, oil recovery ratio
