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 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.

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.
