Integrated petrophysical modeling to identify productive zones in BV8 target of the Samotlorskoye field

Key words: productivity, water cut, lithotype, crossplot, porosity, permeability, oil saturation, modeling.

Reservoirs of BV8 group, Samotlorskoye field, have been under development since 1969. The current water cut: 96%. Well-defined knowledge of volume and location of remaining reserves is required for further successful and economic development of targets alike. The key tool for that is geologic and dynamic simulation modeling. An effective model cannot be generated without a comprehensive petrophysical framework that includes lithologic-mineralogical analysis, optimal porosity estimation with account for log data quality, permeability analysis by lithotypes with honoring actual well performance, initial oil-saturation determination by capillary model and current oil-saturation determination by log data.

On substantiation of license area economic-geological evaluation by hydrocarbon resources and reserves

Key words: unit cell, local structure, hydrocarbon resources, Perm region.

The paper presents the zoning Perm region in size of the unit cells, based on the characteristics of the geological structure, as well as the size and orientation of the local structures. To determine the size, shape and orientation of the unit cells the authors analyzed morphological characteristics of all local structures that have ever been drilled. The analysis was performed with the time and methods of preparation structures. The data were analyzed separately for items of oil zoning sequentially from large to smaller. After the study area, linear dimensions, and azimuthally orientation of the unit cells with additional modules to the program ArcGIS was built grid of unit cells. At the second stage, for each unit cell were calculated recoverable reserves and resources of oil according to their spatial location.

Analysis of reservoir heterogeneity and gas saturation, estimated by well logging data is a basis for reservoir management

Key words: Cenomanian stage, gas reservoir, logging data, well cross section geological heterogeneity, gas flow profile, production optimization.
Efficient flow management from enomanian deposits at Medvezhie field in a group of wells requires consideration of variety in texture and mineralogy of rocks, determination of flow intervals in each well. Solution for the problem can be found applying results of well logs interpretation by TABC method. Reservoir modeling can serve as a merger of the obtained geological characterization and should allow for spacial heterogeneity and saturation determination in the reservoir or it's locations. The model can be taken as a basis for the whole enomanian gas production strategy optimization.

Russian - Norwegian cooperation in the Barents Sea - a strategic and operational challenge

Key words: regional development, Russian interests, Norwegian experience, common interests in the High North creates at potential for cooperation.

Following the delimitation agreement in the Barents Sea new perspectives are outlined for the cooperation in the High North. National Interests and Regional Development are mutual objectives in both countries. However, the strategies and legal framework in obtaining the goals are significantly different. Russia puts priority on state control and strong monopolies, while the Norwegian way is “diversity and multiplicity”. To bridge the activity gap on short term it is an important step that Rosneft and LUKOIL are applying for licenses on the Norwegian shelf. However, more substantial activity is needed and should be followed up with closer cross border cooperation on company level and in developing basic infrastructure.

Once again on the oil recovery

Key words: oil recovery, oil recovery ratio, the methods of enhanced oil recovery, bottomhole zone treatment, the additional production due to methods of enhanced oil recovery and bottomhole zone treatment.

The problems of reserves estimation and the oil recovery ratio determination are considered. It is shown that the oil recovery conceptions depend on the reliability of information on the geological structure of the specific object and applied headway technologies. It is noted that an effective application of the methods of enhanced oil recovery in the fields with hard-to-recover reserves plays the principal role in problems of the innovative design, the organization of works on the creation, testing and implementation of methods of enhanced oil recovery has no less importance. The basic ways to stimulate methods of enhanced oil recovery implementation and improve the final oil recovery ratio are suggested.

Estimate of dual completion effect on field production rate and recovery factor by example of the Romashkinskoye oil field

Key words: multilayered field, layer heterogeneity, dual completion, production rate, oil recovery factor.

Positive effect of dual completion technology on the production rate and the oil recovery factor has been demonstrated. Segregation of productive layers in a multilayered oil field allows reducing layer heterogeneity in a well cross-section, increasing thus drainage area, and ultimately, oil recovery factor.

New lines of the raising of an informativity of geological and hydrodynamic deposit simulation

Key words: modeling, scale effects, formation damage, residual oil, anisotropy of filtering properties.

New lines of the raising of an informativity of geological and hydrodynamic deposits simulation are considered. It is shown, that the standard simulation dataware and used standard commercial simulators do not take into account a whole series of physical and geological aspects of the reservoir nature, in particular, scale effects, anisotropy, formation damage at the long filtration are not taken into account in the modern practice of modeling. At reservoirs recovery assessing the structure and mobility of the residual oil are not taken into account. New approaches to the description of these phenomena are analyzed and their practical applicability is shown.

Analysis of the factors, determining the efficiency of hydrophobiation of producing wells bottom zones

Key words: hydrophobization face zones, layered heterogeneity, anisotropy filtering properties.

The factors, determining the effectiveness of hydrophobization of producing wells bottom zones to reduce production watering, are analyzed. It is shown, that to achieve a positive effect it is necessary to consider the ability of the used reagent to plug the pore space at interaction with water. Stratified heterogeneity of productive strata, sector character of the formation fluid movement in the well bottom zone and the anisotropy of the filtration properties of rocks, caused by stratification of its microstructure, are essential.

Optimization of waterflooding system of the Verh-Tarskoye oil field by means of streamline simulation

Key words: streamline simulation, waterflooding optimization, mature field, wells ranking, experimental validation.

Streamline simulation is a useful tool for optimization of waterflooding system. It shows the paths of fluids flows in the reservoir and visualizes wells interactions. It also helps in quantitative evaluation of wells performance and ranking of production and injection wells by efficiency. In this article the proposals for waterflooding system optimization with the help of streamline simulation in Frontsim for Verh-Tarskoye mature oil field are considered. Efficiency factors of injection wells are calculated. Inefficient injection wells are identified. Stop or decrease of injection in such wells can lead to decrease of watercut and increase of oil rate of connected producers. To keep the balance of reservoir energy, injection from stopped wells can be redistributed into more efficient injectors which provide oil sweeping, not water circulation between production and injection wells.

On the gas separation coefficient at an electric centrifugal pump suction

Key words: electric centrifugal pump (ECP), oil production, oil globule motion, gas emission, gas separation.

At present the derivation of formula for the gas separationcoefficient calculation at the well pump suction is carried out taking into account a number of assumptions and nonmetering acting forces. As a result it is forced to abandon the obtained expression and to suggest empirical formulas proposed by P.D. Lyapkov. However, at the same time the obtained separation coefficient is overestimated. The purpose of this paper is to obtain a theoretical derivation of gas separation coefficient and estimation of its value.
