Abstract In recent years, the Oil and Gas Industry has greatly improved efforts in evaluating the electrical system involved in operating Electrical Submersible Pumps (ESP). The negative effects that poor power quality has on ESP motors equipped with variable speed drives is generally understood by the industry. However, with a strong focus on optimization and reliability, improvements of the power quality provided to our ESP systems has tremendous potential to enhance the ESP lifecycle. This paper will provide a detailed description of the current mitigation technique involving the conventional designs of PWM sinewave filters. Additionally, this paper will outline multiple Case Studies that have been conducted on several wells with ESPs installed, that demonstrate the success of a new design approach for PWM sinewave filters yielding lower electrical distortion and significantly improved motor performance. A detailed analysis evaluating problems and premature failures was performed on existing ESP wells equipped with both "6-step" and PWM operation. Computer simulations executed to analyze the new sinewave filter design showed much lower voltage distortion (< 2%) as well as other important improvements in performance included a very low insertion loss (ie. < 3% drop in voltage at full load) and improvement in PF to near unity at the inverter output. To complete the study, sinewave filters were built, tested and installed in several wells. Field data was gathered providing power quality measurements for electrical distortion, current imbalance, motor temperatures, motor vibration and production rates. The successful sinewave filter design used different tuned frequency parameters than conventional sinewave filters with clear data providing performance improvement. These results showed a substantial reduction in motor temperature leading to confidence in operations regarding the positive effect this would have on lifecycle of downhole equipment. The improvements can be streamlined across other ESP wells in the field leading to improved runtime, decrease in CAPEX & OPEX cost associated with ESPs and other surface equipment eventually leading to a strong cash flow performance for operators.

The Government

Federal tax revenues from the main sectors of the Russian economy after the 1998 crisis are examined in the article. Authors present the structure of revenues from these sectors by main taxes for 1999-2003 and prospects for 2004. Emphasis is given to an increasing dependence of budget on revenues from oil and gas industries. The share of proceeds from these sectors has reached 1/3 of total federal revenues. To explain this fact world oil prices dynamics and changes in tax legislation in Russia are considered. Empirical results show strong dependence of budget revenues on oil prices. The analysis of changes in tax legislation in oil and gas industry shows that the government has managed to redistribute resource rent in favor of the state.

Ruling Elites

The article deals with the issues of political and economic power as well as their constellation on the market. The theory of public choice and the theory of public contract are confronted with an approach centered on the power triad. If structured in the power triad, interactions among states representatives, businesses with structural advantages and businesses without structural advantages allow capturing administrative rents. The political power of the ruling elites coexists with economic power of certain members of the business community. The situation in the oil and gas industry, the retail trade and the road construction and operation industry in Russia illustrates key moments in the proposed analysis.

Geopolitical Risks

The article is devoted to the consideration of geopolitical challenges for the analysis of geoenvironmental risks (GERs) in the hydrocarbon development of the Arctic territory. Geopolitical risks (GPRs), like GERs, can be transformed into opposite external environment factors of oil and gas industry facilities in the form of additional opportunities or threats, which the authors identify in detail for each type of risk. This is necessary for further development of methodological base of expert methods for GER management in the context of the implementational proposed two-stage model of the GER analysis taking to account GPR for the improvement of effectiveness making decisions to ensure optimal operation of the facility oil and gas industry and minimize the impact on the environment in the geopolitical conditions of the Arctic.The authors declare no conflict of interest
