Key words: oil recovery, negative factors, permeability heterogeneity, heterogeneous wettability, PVT properties, production condition of well, reservoir and bottomhole pressure, oil phase permeability, well-drained and weak-drained oil resources, oil recovery mechanism.
The presented work is concerned with oil recovery regularity of UK10 development object of Talinskaya area of Krasnoleninskoye field. Qualitative assessment of mobile oil resources structure is attended. Mobile oil resources are splitted into two types: well-drained and weak-drained, which is essentially distinguished by oil recovery mechanism. Conclusions is based on the situational analysis consist of consideration every possible scenarios of development on the various parts of oil accumulation on the last period.
