Self Help

The objective of this paper is to describe the importance of formation of a pragmatic Energy Optimization Program (EOP) at the concerned oil and gas facilities. Substantial amount of energy savings can be realized by focusing on initiatives that require no investment or so called “self-help” that can easily be implemented without further a due. A “quick fix” initiative involves a nominal investment; it can also be easily executed without the need for detailed project justification. Given the increasing expectations to oil and gas organizations to maintain a competitive edge in the modern global economy have caused the instability of crude oil as the world’s major commercial energy source for the next coming years and greater commitment to reduce greenhouse gas (GHG) emission. Regardless of during high or low crude oil price, energy is certainly a critical business continuity driver for both users and producers. Having significantly greater EOP to explore energy savings opportunities require many efforts including new efficient equipment, new technology, new processes and approaches which should be given a priority. Ideally, EOP focused team shall effectively participate in early design stage of project, so that all significant energy efficiency concepts will be considered in the design. In reality, many energy efficiency efforts may be missed out as a result of loose energy efficiency definition, less competency of design engineers, hectic project schedule and/or resource constraint.

Key Indicators

Large-space buildings feature a sizable interface for receiving solar radiation, and optimizing their shape in the early design stage can effectively increase their solar energy harvest while considering both energy efficiency and space utilization. A large-space building shape optimization method was developed based on the “modeling-calculation-optimization” process to transform the “black box” mode in traditional design into a “white box” mode. First, a two-level node control system containing core space variables and envelope variables is employed to construct a parametric model of the shape of a large-space building. Second, three key indicators, i.e., annual solar radiation, surface coefficient, and space efficiency, are used to representatively quantify the performance in terms of sunlight capture, energy efficiency, and space utilization. Finally, a multi-objective genetic algorithm is applied to iteratively optimize the building shape, and the Pareto Frontier formed by the optimization results provides the designer with sufficient alternatives and can be used to assess the performance of different shapes. Further comparative analysis of the optimization results can reveal the typical shape characteristics of the optimized solutions and potentially determine the key variables affecting building performance. In a case study of six large-space buildings with typical shapes, the solar radiation of the optimized building shape solutions was 13.58–39.74% higher than that of reference buildings 1 and 3; compared with reference buildings 2 and 4, the optimized solutions also achieved an optimal balance of the three key indicators. The results show that the optimization method can effectively improve the comprehensive performance of buildings.

Energy conservation and improving energy efficiency are priority areas for the development of the global economy. The need to increase the energy efficiency of the engineering equipment of buildings is due to both the requirements to reduce the energy consumption of buildings in general, and the increase in the proportion of energy-consuming climate systems used in modern construction. In large modern office, hotel and residential complexes to achieve the greatest energy efficiency it is necessary to use various technical solutions. The main element of an energy-efficient heating system is regulation. Balancing devices allow to not only balance and tune the system at any time of operational period but also serve as stop valves during reparation and diagnostics. Determination of energy savings bases on the average value heat consumption before and after modernization, depending on the type of installed valves or their combination. The focus of the work is hydraulic calculation of the heating system the authors conduct research on the effect of differently balancing fittings on the hydraulics of the heating system.

Main Thing

New breakthrough technologies can have a positive or negative impact on the development of the fuel and energy sector. Therefore, the main thing is to evaluate technologies, analyze their suitability for the industry and determine priorities for future opportunities, i.e., identify technologies that provide new advantages for the energy world, and determine how, when and how their impact will become tangible. In this regard, researchers have determined that the innovative technology of the XXI century, recognized to transform the national and global economy is the blockchain technology. The article provides an overview of blockchain technology, defines the principles of its operation and possible applications, i.e., identifies the mechanism of action of the revolutionary system, as well as presents the players of the oil and gas industry to launch blockchain technology and identifies the advantages of innovative technology used in the oil and gas sector. It is determined that on the basis of the new technology, it is possible to create a single network for digitizing all interaction processes and automating them. The study also shows that the scope of application of blockchain in the oil and gas business is much broader, which determines the possibility of further consideration of a wide range of the need for the use of blockchain technology for the oil and gas industry, as well as its impact on the development of oil and gas companies.

Energy has a strong impact on both economy and ecology. Global economy and ecology need to obtain sustainable and clean sources of energy, which is an issue of financial challenges. Developing countries face problems of energy sourcing due to costs and risks. But using the natural sources of energy in creative ways is cheap and clean. Therefore, developing economies must develop energy strategies based on creative energy solutions. Turkey as a developing country implemented policies to improve renewables and energy efficiency in line with EU requirements. Turkey does not have enough conventional energy but very large renewable energy resources. In this chapter, the large potential of creative energy alternatives in Turkey is explored. The indistinct start of energy savings market and the risks of financing huge energy projects show that Turkey needs to depend on investing in the cheapest forms of creative energy solutions.

For the past few years, the oil and gas industry has faced several economic, geographic and technical challenges largely due to decline in crude oil prices and market volatility. In the quest to address some of these challenges to accelerate production and subsequently maximize ultimate recovery, operators are limited to remote hydraulic and electro-hydraulic monitoring and control of safety valves providing the means of obtaining downhole production data which demands periodic well intervention-based techniques with risk of loss of associated tools. This has highlighted the need for companies to adopt new technology to take advantage of low crude oil price environment, optimizing recovery without interventions and with minimal production interruption. One of the recent improvements in production technologies which can remedy these problems having unique capabilities to do so is the Intelligent Well Completion (IWC) technology. In this paper the utilization of IWC to optimize oil recovery was evaluated. The use of a reservoir simulator, the Schlumberger ECLIPSE-100 simulator, was employed to model an intelligent well. Case study simulations were performed for an active bottom-water drive. Modeling of the Intelligent Well Inflow Control Devices (ICDs) and downhole sensors for the multilaterals was achieved using the Multi-Segment Well model. Optimal IWC technology combination for maximum hydrocarbon recovery and minimal water production was determined using the reactive control strategy (RCS) which indicated a drastic reduction of about 52.1% in water production with a slight drop of 1.5% in field oil efficiency (FOE). The simulation results obtained clearly showed that the utilization of intelligent well-ICDs in Production wells can significantly increase the cumulative oil production and reduce water production.

This book analyzes the Central Asian economies of Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan, from their buffeting by the commodity boom of the early 2000s to its collapse in 2014. The book examines the countries' relations with external powers and the possibilities for development offered by infrastructure projects as well as rail links between China and Europe. The transition of these nations from centrally planned to market-based economic systems was essentially complete by the early 2000s, when the region experienced a massive increase in world prices for energy and mineral exports. This raised incomes in the main oil and gas exporters, Kazakhstan and Turkmenistan; brought more benefits to the most populous country, Uzbekistan; and left the poorest countries, the Kyrgyz Republic and Tajikistan, dependent on remittances from migrant workers in oil-rich Russia and Kazakhstan. The book considers the enhanced role of the Central Asian nations in the global economy and their varied ties to China, the European Union, Russia, and the United States. With improved infrastructure and connectivity between China and Europe (reflected in regular rail freight services since 2011 and China's announcement of its Belt and Road Initiative in 2013), relaxation of UN sanctions against Iran in 2016, and the change in Uzbekistan's presidency in late 2016, a window of opportunity appears to have opened for Central Asian countries to achieve more sustainable economic futures.

The Impact

This chapter is concerned with the role of oil and gas in the economic development of the global economy. It focuses on the context in which established and newer oil and gas producers in developing countries must frame their policies to optimize the benefits of such resources. It outlines a history of the issue over the last twenty-five years. It considers oil and gas as factor inputs, their role in global trade, the role of oil prices in the macroeconomy and the impact of the geopolitics of oil and gas. It then considers various conventional views of the future of oil and gas in the primary energy mix. Finally, it challenges the drivers behind these conventional views of the future with an emphasis on why they may prove to be different from what is expected and how this may change the context in which producers must frame their policy responses.
