Borehole acidization has two objectives: to remove drilling damage at the well face and to enhance formation permeability. Acid applications have been mainly on carbonates, granitic and metamorphic rocks in geothermal wells and on sandstones in oil and gas wells. In geothermal wells, acidizations have been especially useful in removing accumulated scale deposits. Hydrochloric acid is the most commonly used as it has a high dissolving power, a lower cost and is relatively easy to handle. It reacts easily with carbonates but not with silicates in sandstones for which a mixture of hydrofluoric and hydrochloric acid is used. There are no known water well acidizations with hydrofluoric acid. Acidization of limestone water wells with hydrochloric acid has been generally successful in naturally fractured rock with productivity improvements of two or more times the original yield. Second and third acidizations can enhance yields further and are usually economically justifiable. Water well acidizations may benefit from higher injection rates than is currently practised. Acid fracturing is widely used in the oil and gas industry. In water wells it may prove useful in hard crystalline limestones, but not in soft low strength carbonates, such as UK Chalk.

Scada Systems

The paper deals with the migration of SCADA (Supervisory Control and Data Acquisition) systems widely used in the monitoring and management of the oil and gas industry to the cloud computing environment. There arise various problems in data collection, transmission, and processing because of traditional SCADA systems being very expensive, inflexible, and complicated scalability. The transferring of the SCADA system's applications to the cloud environment reduces costs and improves scalability. The purchase of hardware and software is carried out at a lower cost than its installation and maintenance. In the article, the usage of cloud-based SCADA systems has been proposed for easy, safe, reliable and quick collection and processing of data from facilities installed in the oil and gas industry.

Reduction Of Energy Consumption

Groundwater wells are widely used in the energy sector, including for drinking water supplies and as water source wells in the oil and gas industry to increase production of natural gas and petroleum. Water well clogging, which can happen to any well for various reasons, is a serious problem that can lead to increased power costs due to a higher head to the pump, a reduction in the flow rate and various drawdown issues. If rehabilitation procedures do not take place in time, this can result in permanent loss of the well, and a new well must be drilled, which is not a sustainable approach. Rehabilitation methods for water wells usually include mechanical and chemical treatments, and even though these methods are well established and have been used for many years we can still observe many abandoned wells which could be rehabilitated. In this study, sets of cavitation generators are developed and used in combination with common conic hydrodynamic nozzles. This combination reduces the pressure in the system and makes the cleaning setup much lighter and more mobile. The designed nozzles were successfully used in hydrodynamic cleaning of four water wells.

Cost transparency: which levers do you pull when we cannot trust the dials? The continued challenge of understanding what is really driving costs

In the past few years an industry-wide race towards achieving construction milestones took place, which drove behaviours of increased spending. Now the focus is on implementing low-cost operating models to optimise the move towards operations in a lower-priced oil world. KPMG’s recent work and research demonstrates that cost transparency is still a major issue in the upstream oil and gas industry for operators and non-operators. It is clear that it will be difficult to drive out costs and move to the lower cost baselines without significantly improving cost transparency in oil and gas organisations. In KPMG’s research, operators in Australia and the Association of Southeast Asian Nations (ASEAN) were asked about what challenges they saw, and how they were managing cost in the context of cost transparency. The focus of the research covered the following areas: how can you optimise costs if you don’t have transparency? defining the problem and its boundaries; external influences; internal influences and reactions; the increased scrutiny from joint venture partners; the challenge to developing a cost culture; and, the barriers and enablers. Also, the oil and gas industry has invested heavily in a safety first culture. It has made enormous improvements and the culture is permanent. It could be argued that if the industry put a fraction of the same energy in to building a cost conscious culture then it will weather the lower oil price world so much better.

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.

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
