In Russia, since 1972, core correlation relationship between connate water saturation αwc and porosity αwc=f(m) is used for porosity cutoff estimation based on methods which have been generated to find property cutoffs: 1) method of effective porosity me=m(1- αwc) 2) method of dynamic porosity md=m(1- αwc-αor), where αwc and aor-connate water and residual oil saturation Estimation method of property cutoffs is as follows: plot petrophysical correlation relationship me=f(m) and md=f(m), which are usual as line functions with high correlation coefficient. Find graphically or analytically cross points of porosity axis and functions me=f(m) and md=f(m). Sections on this axis intercepted with points me=0 and m d=0 are accepted numerically as porosity cutoffs. Judging by foreign publications, correlation relationships me=f(m) and m d=f(m) are used only in domestic practice of estimating hydrocarbon reserves and thus this method can be considered as Russian know-how. Oil reserves estimated by the method me are in-place reserves, by the method md - producible reserves. Both options of correlation methods estimate matrix cutoffs for carbonate fractured reservoirs.

The article describes experience in application of methodic approaches for asphaltene-resin-paraffin deposits (ARPD) inhibitors and depressor additives (developed in Giprovostokneft OJSC) efficiency study, considering process conditions of oil field and pipeline transportation facilities' functioning, when handling specific oil. Application of ARPD inhibitors and depressors is associated with necessity to prevent ARPD forming in oil field and pipeline systems, to improve oil's transportable properties, to increase safe period of shutdown pipelines' down-time and to reduce start-up pressure, when transportation is restarted. Studies are described by the example of Suzunskoye field's oil. As the result, the selected chemical combined ARPD-inhibiting and depressor properties. Application range for these results is high-viscous and high-setting oil production, gathering and transportation facilities in order to enhance efficiency of their functioning. Use of our results supports frequency of paraffin cutting at equipment reducing by 3-4, deposits are weak and can be easily removed, fluid resistance in pipelines is reduced and cost of fluid transportation, pipeline safe shutdown time is increased and start-up pressure is reduced, when transportation is re-started, reliability and safety of all oil field and pipeline system is enhanced.

The essential prerequisite for effective and innovative activity of R and D institutes in oil industry is related not only with designing of new procedures, but also relates to their application in project design concepts. The paper considers the challenges in process designing of oil industry objects. The authors present the analysis of present day situation in complying with code and normative base that controls the use of subsurface resources as per the current requirements in oil production. Actualization and constant updating of this code and normative base is one of the aspects in innovative development of oil industry. This objective may be achieved through the national association of designers with active involving of specialized self-regulating institutions.

Horizontal and vertical tanks are widely used at oil industry upstream process facilities; they act as vessels for produced water pre-separation or for emulsion "cool" wash through water cushion; at that, vertical wash tanks are widely demanded to handle wellstream at heavy oil fields. Efficiency of tank functioning depends on correct inlet of liquid in the tank, however, as field experience demonstrates, equipment and technology of oil/water mix feed does not meet requirements for liquids' equal apportionment over tank section. Intended to resolve this problem, distribution systems have several configurations; however, none of them completely resolves the problem of specific process load's noticeable inhomogeneity over tank section. Based on the said Giprovostokneft has set the task to develop calculation procedure for hydraulic and structural parameters of distribution system elements to feed liquid in the tank and to develop the most efficient geometric scheme of the distribution system. Results are presented in the article.

The laboratory data on the residual oil saturation and efficiency of waterflood high-viscosity oil displacement from the A4 layer of Bashkirian stage by the fields of the Samara and Ulyanovsk regions are generalized. The rectified correlation dependences of residual oil saturation and waterflood oil displacement efficiency on the reservoir rock permeability and mobility are proposed on the basis of the analysis of laboratory data and values, accepted in the works on the calculation of the oil and gas reserves and the design documents.

The paper provides for the results of laboratory study for reservoir oil viscosity Impact on oil saturation of Bobrikovskoye horfeon and Tournaislan stage reservoirs. Laboratory tests were performed according to OST 39-195-86 using complex reservoir models with sufficiently close average permeability characteristics of coeval deposits and different oil viscosity. Obtained results show that reservoir oil viscosity under studied values has Insignificant effect on residual reservoir oil saturation. In this case, to achieve final water oil displacement factor and residual oil saturation different quantity of water shall be pumped through porous medium depending on value of reservoir oil viscosity.
