The costs of drilling in hard rock depend significantly on the available drilling technology. Conventional drill bits are especially adapted to the needs of the oil and gas industry but they are limited for drilling in crystalline formations. The Electric Impulse Technology offers a promising alternative for this purpose. The splitting effect of electrical explosions inside the rock is used to destroy the rock instead of working mechanical against the compressive strength of the rock. In a project funded by the BMWi (project number 0325253) a drill head was developed, which consists of a pulse power source of up to 500 kV and electrodes for a 12 ¼″ borehole. The drill head is designed for downhole pressures up to 1000 bar and temperatures up to 200 °C. A test stand has been implemented at the TU Dresden. Drilling tests under borehole like conditions could be performed. Drilling speeds of 1 m/h could be proven. The follow-up project started in the end of 2014. The drill head will be optimized and the power supply will be designed. The total system will be used in a test well and investigated.

Abstract As the Oil & Gas industry journeys towards net zero carbon emissions, a lot needs to be done, one of which is the adoption of digital transformation across companies. Decarbonization requires a transformational shift in the way companies operate, how they source, use, consume and think about energy and feedstocks. If the Oil & Gas sector will continue to exist, it must carry out its activities in the safest possible way and digitalizing it will help in achieving this. A survey by Newsweek shows that areas where transformative technologies are having the biggest impact are production-related, operations and maintenance, enhanced recovery, fracking/tight reservoirs, and exploitation at greater depths. Luis Abril of Minsait opined that digital technology enables companies to extract more value from data, using new platforms to share data with the entire organization, suppliers, contractors, and partners. The real-time visualization of data helps optimize decision making. Big data can be analyzed to find answers to questions such as: What piece of equipment is showing signs of wear and should be replaced? What sort of predictive maintenance can be leveraged? What is the most effective fracking approach for this well? AI helps to reduce routine flaring, employ methane capture, optimize production and reservoir management using digital tools such as IoT sensors, digital twins, and virtual reality to model scenarios, monitor operations, track emissions, energy usage and proactively maintain equipment, produce lower-emission products by moving from one hydrocarbon to another (e.g., from coal to natural gas) or creating another product (such as biofuels or syngas). Transformative technologies, particularly IoT, mobility and cloud applications are going to have a profound effect on the future of the oil and gas sector. Investment in these technologies cost a lot which might be difficult for private companies, but it is worth the money in the long run.

Over the years, expenditures of public and private sectors are regulated by the activities in the oil and gas industry. The budget of Nigeria is hinged on the international price of crude oil and any shock on oil price affects the general activities in the country. With quarterly data from the period of 1981Q1 to 2020Q2, the study uses an exponential generalized autoregressive conditional heteroscedasticity approach to examine oil price volatility and inflation level in Nigeria. An augmented Dicky-Fuller unit root test and bound test cointegration approach were used to test for stationarity and existence of long run association among the variables respectively. The study found that negative shocks in real oil price affects the volatility of the inflation level. Also, it was observed that aside real oil price volatility, interest rate and real gross domestic product volatilities affect the volatility of the inflation level. The study therefore recommends among other things that policies meant for diversification of Nigerian economy in areas like industries and agriculture should be adopted to reduce high volatility of the inflation level.

The Subject

The use of diamond in tribological applications in the oil and gas industry is reviewed. The high hardness, strength, and corrosion resistance of diamond make it an attractive option for components that are susceptible to degradation by abrasive, erosive, or adhesive wear; such components may also be prone to corrosion owing to the nature of the environments to which they are often exposed. Applications such as drill bits, bearings, and mechanical seals benefit from the use of diamond, while choke valves are the subject of research programs to assess the suitability of chemical vapor deposition (CVD) diamond for these components. Also discussed are some of the conditions experienced by the components and how the properties of diamond enhance their operating lives.

The development and use of the radial drilling technology has been a controversial issue in the oil and gas industry for a long time. Nowadays, almost all big oil and gas producers deal with the question of its practical use at particular fields. The results of works carried out at carbonate reservoir units of the Orenburg Region were analyzed in the article. The ways to improve the existing technology of radial drilling were also offered. The research objective is to evaluate the technological efficiency of radial drilling application at the fields of the Volga-Ural oil and gas region with carbonate reservoir units. The results of radial drilling were characterized with the help of the detailed geological and field analysis and their quantitative evaluation was given.

The purpose of this paper is to identify the connection between oil prices and the performance of oil and gas, industry and services sectors. The paper is supported by the granger causality and Engle and Granger cointegration tests. The research findings do not support a long-run association between Brent oil prices excluding the case of the Oil and Gas sector index; however, short-run dynamics were recognized. There is no unidirectional causality found in any case. The outcomes of the GARCH model show stable results for all three sectors.

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.

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.
