Key words: the Chukchi Sea, North Chukchi Basin, Arctic Alaska, geological structure, tectonic evolution, stratigraphy, correlation, petroleum systems.

The Russian Chukchi Sea is one of the most remote regions of Eastern Arctic with very high hydrocarbon potential. It is widely believed that the North Chukchi Basin of the Russian Chukchi Sea has similar geological structure and evolution with the famous US North Slope of Alaska petroleum province. Here we discuss the principal tectonic events, present-day structure and stratigraphy, and proposed hydrocarbon systems of North Chukchi Basin.

Key words: Bazhenov formation, basin modeling, unconventional resources, organic porosity.

The case study of Bazhenov formation of Western Siberia shows methodological approach for unconventional hydrocarbon potential assessment with basin modeling tools. The study results include maturity schemes of Bazhenov formation in the study area, volumes of generated hydrocarbons and Bazhenov formation self-sourced potential estimates. A lot of attention paid for creating present day TOC maps and initial TOC restoration as well as calculation of “organic” porosity which is formed when kerogen transforms into hydrocarbons.

Key words: field development optimization, well spacing, production rate.

This paper describes a new method for selection of well spacing and production rate for an oil field. We express net present value as function of well spacing and the production rate. Then we introduce dimensionless parameters that describe optimal well spacing and production rate. Analysis of optimal development parameters shows the effect of the discount rate on the parameters of development. We reveal that overestimation of discounting factor potentially leads to incorrect technical decisions. We illustrate an application of our method with examples of Western Siberia and Yamal oil fields.

The article considers the issues of the involvement of the depositional model in the decisions in field development problems by the example of one of the fields in Western Siberia at the late stage of development. It is shown that the intergrated geological model which connects geological features with field development data should be a basis for forecasting and operational monitoring of the field development.

Key words: managing the development, well-testing, permanent downhole gages (PDG).

Long term downhole production monitoring by permanent downhole gages (PDG) becomes key element of production control system. It allows determining pressure and skin changes with time, well interference and formation changes vs. distance. On base of such information workovers, hydrofractures, acidizing and other treatment and development manage actions are recommended for production enhancement.

Key words: decline rate in oil production, interlaid reservoir, waterflood system, technogenic fracturing.

The most appropriate variant of injection and production wells pattern is always extremely important, because the maximum intensification and recovery factor depend on it. At the stage of water flood system design we should take into consideration all known geological features. Due to the fact that the values of the geological characteristics of the major oil fields have a wide range and distributed locally, the scheme of injection and production wells pattern on the selected areas within the field has to be different. This should be considered in future for planning of geological and technical operations.

Approach to permeability maps construction is presented on the base of well tests results taking into account conceptual geological model. It is shown that creating of permeability map should be based on the all available data from the sedimentological features of the reservoir formation to the results of seismic surveys, core analysis, results of well testing. Predictive ability of the obtained maps can be enhanced by the use of interpolation and smoothing algorithm based on the sedimentological model.

High viscosity oil production is part of hard to recover reserves. However, despite the large high viscosity oil reserves, they are being developed slowly. One of the main problem is the absence of approach to the field development technology selection. Selection of the optimal development strategy of increased-viscosity oil reservoirs through the example of Messoyakhskoye project is shown in the article.

Key words: short-term cycle of operation, marginal well exploitation, energy efficiency.

There are considered matters of efficient marginal well operations. There are basics of mode selection of periodical short-term ESP operations considering the achievement of bottomhole pressure (BHP) and reduction of risks of premature failure of equipment. Achieved results considerably simplify the process of equipment selection, its mode of operation and work adjustments.

Key words: autonomous, above-bit module, axial load, bit speed, station of geological and technological researches.

Operations with bottomhole above-bit module were carried out. Obtained are the results, allowed to reveal the technical and technological problems: the station of geological and technological researches doesn't give true information about bottomhole conditions and modes; the growth of bottomhole pressures at the pump switching doesn't allow to maintain a constant bottom pressure, which can greatly exceed the reservoir one; it is necessary to develop a new generation of bottomhole information systems.

Key words: Igarka zone, Jurassic formations, lithological and stratigraphic traps.

The area under review covers a part of the Turukhan river basin, extended from the Sovetsky Lakes latitude to the Kostrovsky area. Acoording to petroleum zonation, it belongs in the most part to the Eloguy-Turukhansk oil and gas area. The analysis of the seismic-geological features of Jurassic formations and the geological structure comparison for the area under review and the well-explored Krasnoleninsk oil and gas area leads to conclusion that the South Igarka zone has the prerequisites for hydrocarbon accumulation in the Lower Jurassic lithological and stratigraphic traps.

Key words: South-Tatar uplift, Devonian terrigen mass, relative amplitude, gravimetrical arlgillaceous, regression dependence, Larionovs dependence pallet.

The paper provides the grounds for validation of Larionov’s template equation (Gubkin Russian State University of Oil and Gas), currently applied to the main oil producing provinces of the Volga-Ural basin, located within the South-Tatar Arch (Bashkortostan). The conventional interpretation of GR logs to determine the clay content in a reservoir generally involves the well-established Larionov template equation. Since the nature of this relation depends on the lithology of the rock, the organic matter content, and the sedimentology it is desirable to specify the template for the particular rocks not only in terms of certain provinces but also in terms of individual fields.
