Genetic types and nature of fluid of hydrocarbon deposits south-east of Western Siberia

Key words: Western Siberia, the genetic types of oils, the conditions of formation of deposits, the mixed type of oil, gas isotopy, the molecular parameters of oils.

On the basis of molecular and isotopic parameters of oil and gas shows the participation of different source rocks in the formation of deposits of the south-east of Western Siberia. The three main genetic types are distinguished among the studied oils. They were generated source rocks of the Upper Jurassic (Bazhenov type), Jurassic and Triassic (Togur type) and Paleozoic (Paleozoic type). Shown that many hydrocarbon fluids do not belong to any of the selected type, and are mixed fluids.Scheme of deposits formation of oil and gas Kazanskoye field was proposed based on the investigation results of oils, condensates and gases.

Conditions of formation fault-bounded oil reservoirs in the northern part of the Varandey-Adzvinskaya zone

Key words: Sorokin Swell, fault-bounded oil reservoirs, Lower Devonian, new exploration directions.

Based on review of the geological structure, basin history and evolution of hydrocarbon systems of the Varandey-Adzvinskaya zone, the authors made a conclusion of favorable conditions for the fault-bounded traps for oil accumulations at the eastern flank of the Sorokin Swell. The main reservoirs are related to the Lower Devonian formations. The region had several stages with different oil migration paths due to tectonic reconstruction. Structure of the nearby oil fields supports the proposed concept, making a good basis for new exploration directions.

Approach to a new wells performance planning in a low-permeability reservoirs

Key words: hydrodynamic modeling, low-permeability and highly heterogeneous reservoir, high production rate decline for the new wells, regularization of the inverse problem solving.

In this paper a semi-analytical approach for well productivity calculation in low-permeability and highly heterogeneous reservoir is proposed. Model considered allows explaining a high production rate decline for the wells operating in such conditions. Method of different interlayers flow capacity determination is considered based on identification of connected and isolated parts of the reservoir during waterflooding. Integration of rate transient analysis and steady-state production rate evaluation is used. Technique described can be used for the prediction of new wells production rate.

Automatic well test data processing: a time series wavelet analysis approach

Key words: well test, wavelet analysis, time series.

This paper discusses perspectives of automatic well test data processing.  Well test data treated as a non-stationary time series can be studied by means of wavelet analysis. The approach suggested allows one to carry out well test data denoising and smoothing, recognize informative intervals in telemetry system curves and flow regimes in pressure response plots. In order to illustrate the method efficiency, field examples are presented.

Key words: exploration of new deposits, reserves increacing, production test (perforation), initial oil rate.

The paper illustrates the comprehensive approach towards the discovery of the “lost” deposits at presently operated fields which allows revealing the significant potential to increase the oil reserves. The practical efficiency of the considered approach (“Search”) and the commissioning of the “lost” deposits into the process of active field development allows building-up the reserves and oil production at minimum capital investments. The results of this works are the annual basis for individual program of further well studies. The realization of the program to evaluate the resource base in 2010 - 2011 has enabled to discover 17 new pools at 15 deposits. The majority of new pools has been commissioned into active operation and has resulted to the increased total oil production.

Recovery of wettability of core samples in preparation to penetration tests

Key words: wettability, core, oil, water, lab test.

In the present work the results of comprehensive analysis on estimation of wettability using the samples of Jurassic deposition of terrigenous profile of oil deposit are presented. Changes in wettability were estimated by two well-known Tulbovich and Amott methods with extracted samples. The influence of wettability on relative permeability to phase was investigated. As a result of the investigations remarkable change in wettability coefficient has been shown to occur during the first 24 hours. The increase in curing time in stratal conditions does not effect on wettability coefficient and permeability to phase.

The authors consider the experience in abandoning the lengthy shut-downs in oil treatment processes while processing the heavy asphalt/wax content oil at Yakushkinskaya Oil Treatment Plant.

They have discovered the objects with non-effective demulsifier usage as well as the objects where these demulsifiers have been used in excess (using the methods of microscopy, of measuring interface and surface tensions in water-oil systems, of thermal and chemical studies, etc.).

Recommendations on the most effective demulsifiers are made. Finally due to the use of CTX-5 effective demulsifier and the overall reduction in its demulsifier application they have stabilized the process oil treatment at this process facility.

The problems on enhanced oil recovery in fields of Russia are considered. The dynamics of the average producible oil recovery factor taking into account commercial development of fields and increasing the share of hard-to-recover reserves is given. It is shown that the carrying out of geological and technical measures, the use of enhanced oil recovery and stimulation oil production methods contribute to producible oil index growth, but require significant costs. The necessity of government regulation and promotion of activities, aimed at producible oil index increasing, is marked.

The main directions of the associated gas utilization

Key words: production well, the complications in the extraction of oil, technology of gas utilization, utilization of associated petroleum gas.

Due to rising energy prices and the gradual depletion of existing recourse there is the question of reducing the loss of energy and efficient way to use existing resources. Associated petroleum gas (APG) - is a by-product of oil production, which is a valuable raw material for the chemical and energy industries. There are a lot of interrelated reasons for associated gas is not fully utilized in the oil fields in Russia, such as technological, economic and environmental reasons. Positive economic effect can be achieved by the accomplishment of the target (95% set by the Government of Russia) as a result, a reduce of penalties for emissions, and by using of gas as an energy source and chemical feedstock.

Experience of enhanced oil recovery by CO2 injection in the U.S. fields

Key words: oil recovery factor (ORF), the methods of enhanced oil recovery (EOR), CO2 injection, additional oil production.

Various methods of enhanced oil recovery in the U.S. fields are considered. It is shown that injection of CO2 is the most common and effective method, since the largest amount of additional oil production is achieved owing to it. The data on the additional oil production in the U.S. due to a miscible and immiscible displacement at CO2 injection are given. The further increase of oil production by this method is forecasted.
