* Mechanical methods * Chemical methods * Combination methods Description / back cover text: Well activation is one of the most important aspects in the oil and gas industries and nitrogen gas is predominately used. The gas, being light, is sent down the producing reservoir which will enhance the production or improve the flow of crude oil. In addition to the methods used to increase production there are several problems like sand production and water production from the producing wells. Sand production occurs when the destabilizing stresses at the formation face exceed the strength of the natural arching tendencies and/or grain-to-grain cementation strength. Ideally, during oil production, the formation should be porous, permeable and well consolidated through which hydrocarbons can easily flow into the production wells. But sometimes, especially during production from unconsolidated sandstone reservoirs, the produced hydrocarbons may also carry large amounts of sand into the well bore and sand entering production wells is one of the oldest problems faced by oil companies and one of the toughest to solve. These unconsolidated formations may not restrain grain movement, and produce sand along with the fluids especially at high rates. Water production is also a problem that many reservoir or production engineers face in day-to-day life. As engineers we should be able to decide whether water control solutions should be applied or not. The excess production of water is caused by the depletion of the reservoir and simply sweeps away most of the oil that the reservoir can produce. This book gives an information how well activation using nitrogen is carried out, and how sand control and water control issues can be resolved.

First book to provide a thorough overview of the law surrounding PPPs in the MENA region; this is of interest because the area is adopting a more free market philosophy since the Arab Spring.

Institutions shape states, society, businesses, and the interactions between them. Understanding how these interactions shape the growth paths of different countries is crucial to monitoring policy outcomes and gauging creditable impact. The Growth Paths of State-Society Relations highlights how different state-society relations have developed, the power relationships that characterize their different forms or modes, and the wider growth paths that are likely to emerge as a result. Combining case studies with empirical and theoretical game analysis, Mohamed Ismail Sabry presents four State-Business-Labor Relations (SBLR) modes for considering the power relationships at play in these interactions. Analyzing four significant case studies featuring Germany, the USA, China, and Russia, Sabry investigates the emergence of these various modes, particularly whether they arise out of institutional settings or special socioeconomic or historical circumstances. Considering variables such as levels of productivity, long-run economic growth, inequality, and sustainability, chapters also discuss how the SBLR modes affect the growth paths of each example country, particularly through policies related to Technology and Industry 4.0, Green transformation, and social welfare. Providing a rationale for institutional change as well as suggestions for power restructuring within a state-society relationship, The Growth Paths of State-Society Relations offers a unique and nuanced analysis of the perpetual interplay between government, business, and society.

This book examines how socioeconomic and institutional factors shaped the development of Socialism and its two contending variants of Social Democracy and Communism, investigating why each of these factions enjoyed varying levels of popularity in different societies between 1840 and 1945. It places a special focus on a number of factors including: inequality; industrialization; urbanization; political freedoms; literacy and education; national sentiments; ethnic fractionalization and other cultural factors. This important study offers a detailed and thorough analysis combining theory, empirical data and a number of important case studies reflecting the different dimensions of Socialism. It offers perspectives on the strength or lack thereof of Social Democracy and Communism during this period across a number of countries, including, Russia, Germany, Sweden, Britain, France, the United States, China, Mexico and many more. The work's multi-faceted approach provides a rich and thorough analysis of Socialism during this period with new and valuable insights stemming from its unique combination of historic analysis, political theory and institutional economics.

This book provides a comprehensive overview of the law surrounding PPPs in the Middle East and North African region. The significance of liberalised and integrated Public Private Partnership Contracts as an essential component of the world legal and policy order is well documented. The regulation of PPPs is justified economically to allow for competition in the relevant public service and to achieve price transparency, thus resulting in significant savings for the public sector. In parallel to the economic justifications, legal imperatives have also called for the regulation of PPPs in order to allow free movement of goods and services and to prohibit discrimination on grounds of nationality. The need for competitiveness and transparency in delivering public services through PPPs is considered a safeguard to achieve international standards in delivering public utility services. First, it assesses the compatibility of the current PPPs legislation and regulation in the MENA region with the international standards of legislation and regulation prevalent in many other countries, including the UK, France and Brazil. Secondly, it compares the practices in the MENA region with those of international bodies such as the OECD and World Bank. Comparisons are then made between the MENA countries and those in Europe and Asia with regard to the influence of culture, policy and legal globalization. The book will be of interest to scholars and students in the field of international contract law, public law and state contracts, finance law and private law.

This book documents some of the most recent advances on the physical layer of the Internet of Things (IoT), including sensors, circuits, and systems. The application area selected for illustrating these advances is that of autonomous, wearable systems for real-time medical diagnosis. The book is unique in that it adopts a holistic view of such systems and includes not only the sensor and processing subsystems, but also the power, communication, and security subsystems. Particular attention is paid to the integration of these IoT subsystems as well as the prototyping platforms needed for achieving such integration. Other unique features include the discussion of energy-harvesting subsystems to achieve full energy autonomy and the consideration of hardware security as a requirement for the integrity of the IoT physical layer. One unifying thread of the various designs considered in this book is that they have all been fabricated and tested in an advanced, low-power CMOS process, namely GLOBALFOUNDRIES 65nm CMOS LPe.

This book describes the design and implementation of an electronic subsystem called the frequency synthesizer, which is a very important building block for any wireless transceiver. The discussion includes several new techniques for the design of such a subsystem which include the usage modes of the wireless device, including its support for several leading-edge wireless standards. This new perspective for designing such a demanding subsystem is based on the fact that optimizing the performance of a complete system is not always achieved by optimizing the performance of its building blocks separately. This book provides "hands-on" examples of this sort of co-design of optimized subsystems, which can make the vision of an always-best-connected scenario a reality.

This is the first monograph addressing RF CMOS power amplifier design for emerging wireless standards. The focus on power amplifiers for short is distance wireless personal and local area networks (PAN and LAN), however the design techniques are also applicable to emerging wide area networks (WAN) infrastructure using micro or pico cell networks. The book discusses CMOS power amplifier design principles and theory and describes the architectures and tardeoffs in designing linear and nonlinear power amplifiers. It then details design examples of RF CMOS power amplifiers for short distance wireless applications (e, g., Bluetooth, WLAN) including designs for multi-standard platforms. Design aspects of RF circuits in deep submicron CMOS are also discussed.

Low-Voltage CMOS Operational Amplifiers: Theory, Design and Implementation discusses both single and two-stage architectures. Opamps with constant-gm input stage are designed and their excellent performance over the rail-to-rail input common mode range is demonstrated. The first set of CMOS constant-gm input stages was introduced by a group from Technische Universiteit, Delft and Universiteit Twente, the Netherlands. These earlier versions of circuits are discussed, along with new circuits developed at the Ohio State University. The design, fabrication (MOSIS Tiny Chips), and characterization of the new circuits are now complete. Basic analog integrated circuit design concepts should be understood in order to fully appreciate the work presented. However, the topics are presented in a logical order and the circuits are explained in great detail, so that Low-Voltage CMOS Operational Amplifiers can be read and enjoyed by those without much experience in analog circuit design. It is an invaluable reference book, and may be used as a text for advanced courses on the subject.

As MOS devices are scaled to meet increasingly demanding circuit specifications, process variations have a greater effect on the reliability of circuit performance. For this reason, statistical techniques are required to design integrated circuits with maximum yield. Statistical Modeling for Computer-Aided Design of MOS VLSI Circuits describes a statistical circuit simulation and optimization environment for VLSI circuit designers. The first step toward accomplishing statistical circuit design and optimization is the development of an accurate CAD tool capable of performing statistical simulation. This tool must be based on a statistical model which comprehends the effect of device and circuit characteristics, such as device size, bias, and circuit layout, which are under the control of the circuit designer on the variability of circuit performance. The distinctive feature of the CAD tool described in this book is its ability to accurately model and simulate the effect in both intra- and inter-die process variability on analog/digital circuits, accounting for the effects of the aforementioned device and circuit characteristics. Statistical Modeling for Computer-Aided Design of MOS VLSI Circuits serves as an excellent reference for those working in the field, and may be used as the text for an advanced course on the subject.

This volume contains the proceedings of a workshop on Analog Integrated Neural Systems held May 8, 1989, in connection with the International Symposium on Circuits and Systems. The presentations were chosen to encompass the entire range of topics currently under study in this exciting new discipline. Stringent acceptance requirements were placed on contributions: (1) each description was required to include detailed characterization of a working chip, and (2) each design was not to have been published previously. In several cases, the status of the project was not known until a few weeks before the meeting date. As a result, some of the most recent innovative work in the field was presented. Because this discipline is evolving rapidly, each project is very much a work in progress. Authors were asked to devote considerable attention to the shortcomings of their designs, as well as to the notable successes they achieved. In this way, other workers can now avoid stumbling into the same traps, and evolution can proceed more rapidly (and less painfully). The chapters in this volume are presented in the same order as the corresponding presentations at the workshop. The first two chapters are concerned with fmding solutions to complex optimization problems under a predefmed set of constraints. The first chapter reports what is, to the best of our knowledge, the first neural-chip design. In each case, the physics of the underlying electronic medium is used to represent a cost function in a natural way, using only nearest-neighbor connectivity.

This book will introduce design methodologies, known as Built-in-Self-Test (BiST) and Built-in-Self-Calibration (BiSC), which enhance the robustness of radio frequency (RF) and millimeter wave (mmWave) integrated circuits (ICs). These circuits are used in current and emerging communication, computing, multimedia and biomedical products and microchips. The design methodologies presented will result in enhancing the yield (percentage of working chips in a high volume run) of RF and mmWave ICs which will enable successful manufacturing of such microchips in high volume.

Very large scale integration (VLSI) technologies are now maturing with a current emphasis toward submicron structures and sophisticated applications combining digital as well as analog circuits on a single chip. Abundant examples are found on today's advanced systems for telecom munications, robotics, automotive electronics, image processing, intelli gent sensors, etc .. Exciting new applications are being unveiled in the field of neural computing where the massive use of analog/digital VLSI technologies will have a significant impact. To match such a fast technological trend towards single chip ana logi digital VLSI systems, researchers worldwide have long realized the vital need of producing advanced computer aided tools for designing both digital and analog circuits and systems for silicon integration. Ar chitecture and circuit compilation, device sizing and the layout genera tion are but a few familiar tasks on the world of digital integrated circuit design which can be efficiently accomplished by matured computer aided tools. In contrast, the art of tools for designing and producing analog or even analogi digital integrated circuits is quite primitive and still lack ing the industrial penetration and acceptance already achieved by digital counterparts. In fact, analog design is commonly perceived to be one of the most knowledge-intensive design tasks and analog circuits are still designed, largely by hand, by expert intimately familiar with nuances of the target application and integrated circuit fabrication process. The techniques needed to build good analog circuits seem to exist solely as expertise invested in individual designers."

This book introduces the concept of voltage-controlled-oscillator (VCO)-based analog-to-digital converters (ADCs). Detailed explanation is given of this promising new class of high resolution and low power ADCs, which use time quantization as opposed to traditional analog-based (i.e. voltage) ADCs.

Analog and mixed signal integrated systems of today and tomorrow will be very complex, as they meet the challenge and increased demand for higher levels of integration in a System on Chip (SoC). Current and future trends call for pushing system integration to the highest levels in order to achieve low cost and low power for large volume products in the consumer and telecom markets, such as feature-rich handheld battery-operated devices. In today s analog design environment, a fully integrated CMOS SoC design may require several silicon spins before it meets all product specifications and often with relatively low yields. This results in significant increase in development cost, especially that mask set costs increase exponentially as feature size scales down.

This book is devoted to the subject of adaptive techniques for smart analog and mixed signal design whereby fully functional first-pass silicon is achievable. To our knowledge, this is the first book devoted to this subject. The techniques described should lead to quantum improvement in design productivity of complex analog and mixed signal systems while significantly cutting the spiraling costs of product development in emerging nanometer technologies. The underlying principles and design techniques presented are generic and would certainly apply to CMOS analog and mixed signal platforms in high volume, low-cost wireless, wire line, and consumer electronic SoC or chip set solutions.

Adaptive Techniques for Mixed Signal Sytem on Chip discusses the concept of adaptation in the context of analog and mixed signal design along with different adaptive architectures used to control any system parameter. The first part of the book gives an overview of the different elements that are normally used in adaptive designs including tunable elements as well as voltage, current, and time references with an emphasis on the circuit design of specific blocks such as voltage-controlled transconductors, offset comparators, and a novel technique for accurate implementation of on chip resistors. While the first part of the book addresses adaptive techniques at the circuit and block levels, the second part discusses adaptive equalization architectures employed to minimize the impact of ISI (Intersymbol Interference) on the quality of received data in high-speed wire line transceivers. It presents the implementation of a 125Mbps transceiver operating over a variable length of Category 5 (CAT-5) Ethernet cable as an example of adaptive equalizers."

The book reports modeling and simulation techniques for substrate noise coupling effects in RFICs and introduces isolation structures and design guides to mitigate such effects with the ultimate goal of enhancing the yield of RF and mixed signal SoCs. The book further reports silicon measurements, and new test and noise isolation structures. To the authors knowledge, this is the first title devoted to the topic of substrate noise coupling in RFICs as part of a large SoC.

Radio Design in Nanometer Technologies is the first volume that looks at the integrated radio design problem as a "piece of a big puzzle," namely the entire chipset or single chip that builds an entire wireless system. This is the only way to successfully design radios to meet the stringent demands of today 's increasingly complex wireless systems.
