Oil Rim

The oil rim reserves development suggests complexity in maintaining the balance of gas and oil withdrawals from the reservoir, choosing the optimal well design and geosteering, justifying well operation conditions, etc. In addition, gas and oil reservoir can be complicated by diagenetic alterations of deposits, blocked structure, abnormal thermobaric conditions. The paper presents the results of conceptual approach to the Botuobinskiy horizon’s oil rim development design at the Chayandinskoye oil and gas condensate field with the presence of the above complications. This experience can be applied to assess the majority of fields in Eastern Siberia.

Electric Centrifugal Pump

Currently, 50-60 percents of power consumption in oil fields falls on mechanized oil production. The specificity of the operation of a submersible electric centrifugal pump (ESP), powered by a submersible electric motor (SEM) as consumers of electricity, is due to their operation at a considerable distance from the earth’s surface, the variable nature of the load, the aggressiveness of the produced fluid, and the presence of an extended cable line. (Research objective) To study devices for improving the quality of electricity in the oil industry. (Materials and methods) The results of the survey of the parameters of power consumption of the Novoportovskoe oil and gas condensate field of the PREO «Yamal» Network district No. 1 Kust 18 KTP 10 / 0.4 kV No. 1 input-2. (Results and discussion) The results of studies of the parameters of electricity at the Novoportovskoye oil and gas condensate field have shown that it is advisable to use devices that improve the quality of electricity. Devices can be different, both in design and in scope. Such as voltage stabilizers, phase voltage balancing devices, reactive power compensation devices, filter compensating devices, active mains filters. (Conclusions) Having considered the variety of devices on the market that improve the quality of electricity, as well as devices that compensate for reactive power, it is advisable to use static thyristor reactive power compensators manufactured by JSC Electrointer, Serpukhov.

Global Demand

As global demand for energy supplies grew, Russia's Far East and Eastern Siberia in 2013 acquired ever more importance in the region's geopolitics. Moscow and Beijing reached accord on joint development of key oil fields in Eastern Siberia. But Moscow used arms sales to Vietnam as part of an apparent effort to thwart Chinese hegemony in the South China Sea. Still, just as Russian comparative economic advantage with Europe and the West has derived primarily from oil and gas, so has integration with Asia hinged on energy.

The Yamal Peninsula

A large number of gas and gas condensate fields are located in the West Siberian mega-province and, to increase gas and gas condensate production levels, deposits located on the Yamal Peninsula should be introduced into development. Deposits of the Yamal Peninsula are complex-built deposits, Neocomian and Jurassic deposits have abnormally high reservoir pressure with a reservoir temperature of more than 100 ° C.  The Bovanenkovo oil and gas condensate field is the largest in terms of gas reserves in the Yamal Peninsula; on this example, in this article we will study the issues of restoring the reservoir properties of reservoir rocks and increasing the flow of hydrocarbons.  To select the optimal technology and composition for conducting water shutoff treatment, it is necessary to take into account the following factors: which reservoirs represent the reservoir, the percentage of water cut in the recoverable reserves, the tightness of the production string, the current flow rate of the well during operation at constant reservoir pressure, because each field needs an individual approach with a choice suitable water shuto-ff treatment technology.

Summary A common approach to forecast production from unconventional reservoirs is to extrapolate single-phase flow solutions. This approach ignores the effects of multiphase flow, which exist once the reservoir pressure falls below the bubble/dewpoint. This work introduces a new two-phase (oil and gas) flow solution suitable to extrapolating oil and gas production using scaling principles. In addition, this study compares the application of the two-phase and the single-phase solutions to estimates of production from tight-oil wells in the Wolfcamp Formation of west Texas. First, we combine the oil and the gas flow equations into a single two-phase flow equation. Second, we introduce a two-phase pseudopressure to help linearize the pressure diffusivity equation. Third, we cast the two-phase diffusion equation into a dimensionless form using inspectional analysis. The output of the model is a predicted dimensionless flow rate that can be easily scaled using two parameters: a hydrocarbon pore volume and a characteristic time. This study validates the solution against results of a commercial simulator. We also compare the results of both the two-phase and the single-phase solutions to forecast wells. The results of this research are the following: First, we show that single-phase flow solutions will consistently underestimate the oil ultimate recovery factors (URFs) for solution gas drives. The degree of underestimation will depend on the reservoir and flowing conditions as well as the fluid properties. Second, this work presents a sensitivity analysis of the pressure/volume/temperature (PVT) properties, which shows that lighter oils (more volatile) will yield larger recovery factors for the same drawdown conditions. Third, we compare the estimated ultimate recovery (EUR) predictions for two-phase and single-phase solutions under boundary-dominated flow (BDF) conditions. The results show that single-phase flow solutions will underestimate the ultimate cumulative oil production of wells because they do not account for liberation of dissolved gas and its subsequent expansion (pressure support) as the reservoir pressure falls below the bubblepoint. Finally, the application of the two-phase model provides a better fit when compared with the single-phasesolution. The present model requires very little computation time to forecast production because it only uses two fitting parameters. It provides more realistic estimates of URFs and EURs, when compared with single-phase flow solutions, because it considers the expansion of the oil and gas phases for saturated flow. Finally, the solution is flexible and can be applied to forecast both tight-oil and gas condensate wells.

The article is devoted to an analysis of the oil well construction in the fields of the Talakan group of Eastern Siberia. The low quality of the construction of oil wells is explained based on geological structure of the reservoir and the conditions of its formation, particulary, the complications encountered during drilling are given. Based on the analysis, it was found that the use of traditional monosalt and salt-saturated drilling muds is not effective enough to simultaneously solve the problems of exposing intervals of salt deposits and high-quality primary exposing of reservoirs. Based on the literature data analysis and the experience of building the first exploratory wells in Eastern Siberia, the use of hydrocarbon-based flushing liquids is justified. As a result of theoretical and laboratory studies, the compositions of invert-emulsion drilling fluids are proposed of hydrocarbons, which are available in the conditions of fields in Eastern Siberia. The results of studies for determining the effect of flushing fluids on the reservoir properties of the V10 reservoir of the Vostochno-Alinskoye oil and gas condensate field showed that recovery of core permeability after exposure to hydrocarbon-based flushing liquid was on average 90 %, which is significantly higher compared to the effect of water-based drilling muds, where the recovery coefficient is 23 %.
