In recent years, production decline-curve analysis has become the most widely used tool in the industry for oil and gas reservoir production analysis. However, most curve analysis is done by computer today, promoting a "black-box" approach to engineering and leaving engineers with little background in the fundamentals of decline analysis. Advanced Production Decline Analysis and Application starts from the basic concept of advanced production decline analysis, and thoroughly discusses several decline methods, such as Arps, Fetkovich, Blasingame, Agarwal-Gardner, NPI, transient, long linear flow, and FMB. A practical systematic introduction to each method helps the reservoir engineer understand the physical and mathematical models, solve the type curves and match up analysis, analyze the processes and examples, and reconstruct all the examples by hand, giving way to master the fundamentals behind the software. An appendix explains the nomenclature and major equations, and as an added bonus, online computer programs are available for download.

The use of fracking is a tremendously important technology for the recovery of oil and gas, but the advantages and costs of fracking remain controversial. This book examines the issues and social, economic, political, and legal aspects of fracking in the United States. Hydraulic fracturing of oil and gas wells-known commonly as "fracking"-has been in use in the United States for more than half a century. In recent years, however, massive expansion of shale gas fracturing across the nation has put fracking in the public eye. Is fracking a "win win" like its proponents say, or are there significant costs and dangers associated with the use of this energy production technology? This book examines fracking from all angles, addressing the promise of the United States becoming energy independent through the use of the process to tap the massive amounts of natural gas and oil available as well as the host of problems associated with fracking-groundwater contamination and increased seismic activity, just to mention two-that raise questions about the long-term feasibility of the process as a source of natural gas. The first part of the book provides a historical background of the topic; a review of technical information about fracking; and a detailed discussion of the social, economic, political, legal, and other aspects of the current fracking controversy. The second part of the book provides a host of resources for readers seeking to learn even more in-depth information about the topic, supplying a chronology, glossary, annotated bibliography, and profiles of important individuals and organizations. Written specifically for students and young adults, the content is accessible to readers with little or no previous knowledge regarding fracking. Provides readers with a complete historical review of the origins, development, and expansion of the use of fracking Explains the technical principles related to the use of fracking in clear, nontechnical language Presents an unbiased review of the arguments for and against the use of fracking for the recovery of oil and gas Supplies a summary of the history of the use of fracking in the United States

This book explores sustainable mining knowledge, assessing researchers on the impacts of waste and new approaches to negotiating these impacts. Mining has always been a profitable venture; however, it comes with several boons and banes. The significant advantages of mining include employment generation, the establishment of townships and trade centers, and socio-economic growth. However, the mining activity is a significant cause of environmental degradation, including soils, atmosphere, water, solid wastes, changed topography, and health hazards. This book emphasizes value-added products from mining wastes and innovations for balancing environment, ecology, and economy. This book is designed for miners, policymakers, professionals, researchers, scientists, industrialists, and environmental agencies.

The, Uranium Seekers, saga began in 1976 when world-famous Hollywood, California photographer, Martin, was contracted to come to Utah and begin documenting, paying photographic tribute to, uranium miners, native Americans, and the Vanadium King uranium and vanadium mines on Temple Mountain, Emery County, Utah. The essence of the project was to pay tribute to the persons who traversed Zane Grey's and John Ford's great western expanse in search of uranium ore, one rock at a time, from before Madame Curies trips to the, then, present, and to remind the world's public that uranium was, and still is, used to kill, not humanity, rather cancer. I harbored the hope that by going back to the first uranium rocks the nuclear industry would re-evaluate the physical structure of nuclear reactors, one cubic yard at a time. Nuclear reactors, when built, witness Fukushima Daiichi, are still being created with too much haste. Like the uranium miners themselves, it's the hands of the humanity who cast the cement forms in which the reactors rest which determines safety. I also, rather naively, hoped when uranium's harmonous utilization was embraced its destructive military reality, throughout the world, would melt. Even with the support of the fine Beverly Hills, California literary agent, Clyde M. Vandeburg of Vandeburg-Linkletter Associates who represented Ronald and Nancy Reagan, Barry Goldwater, and many others at the time, the national and international events at Three-Mile Island and Chernobyl put Uranium Seekers and Martins great photographs to bed for decades. However, recently I learned the Utah Historical Quarterly Unpublished Manuscripts from the Department of Community and Culture at the Utah State Archives had harbored some of the manuscript material for decades and the recent events at Fukushima Daiichi made uranium part of the international conversation once again, I decided to dust off Martin's work and snatches of the original material for Uranium Seekers.

Finding a new oil and gas discovery and evaluating its volume is a difficult and challenging task, and yet there is very little published on the topic. Luiz Amado delivers a one-of-a-kind introductory guide titled "Reservoir Exploration and Appraisal. "Providing logistical instruction and processes for the entire exploration and appraisal process, Amado furnishes the guidance, workflow, and practical recommendations needed based on real-world scenarios. Written by an engineer with over 15 years of experience in the North Sea, Gulf of Mexico, South America and West Africa, "Reservoir Exploration and Appraisal" equips engineersand economists with expert advice on critical subjects such as detailed methods of estimating recovery factors, creating production curves using either simple or complex approaches, understanding main fluid and rock properties that govern volume and productivity, and communicating examples of field case evaluations, including deepwater projects.

Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. But only about 10 percent of a reservoir's original oil in place is typically produced during primary recovery. Secondary recovery techniques to the field's productive life generally by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place.
In the past two decades, major oil companies and research organizations have conducted extensive theoretical and laboratory EOR (enhanced oil recovery) researches, to include validating pilot and field trials relevant to much needed domestic commercial application, while western countries had terminated such endeavours almost completely due to low oil prices. In recent years, oil demand has soared and now these operations have become more desirable. This book is about the recent developments in the area as well as the technology for enhancing oil recovery. The book provides important case studies related to over one hundred EOR pilot and field applications in a variety of oil fields. These case studies focus on practical problems, underlying theoretical and modelling methods, operational parameters (e.g., injected chemical concentration, slug sizes, flooding schemes and well spacing), solutions and sensitivity studies, and performance optimization strategies. The book strikes an ideal balance between theory and practice, and would be invaluable to academicians and oil company practitioners alike.

Economic skill is an essential partner to technical skill in every step of the mining process. An economic "mindset" begins before the first drill hole. This new book will help you effectively direct mining operations through the use of innovative economic strategies.

The text covers what is meant by a cost-effective mining scheme, the economics of information, and the procedures for rational evaluation of uncertain projects. It defines "ore" from an economic perspective and covers the influence of scheduling on ore reserves.

Discounted cash flow techniques, the most widely used evaluation technique for investment decision making, is covered in detail. The assumption of the use of spreadsheets is unique to this book. The application of DCF techniques in an operating mine environment is given expanded coverage and examples are drawn from real-life studies.

The differences between economic decision-making--a forward-looking task--and the reporting of results via accounting methods--a backward-looking activity--are reviewed. Capital and decision-making procedures associated with capital investments in a risk environment are given extensive coverage. Case studies for capital investment in an operating mine are included. Comprehensive examples investigate "value" from a risk-reduction perspective and from an "expected return on investment" perspective.

This book offers solutions to the problem that many mining projects fail to achieve expectations because of their inability to adapt to change. A new technique is explained that allows calculation of capital that is "at risk" from capital that is not at risk. This promises significant advances in the way that investments are made and capital is valued in the industry.

Drilling technology has evolved in order to get at the increasingly harder to find oil, and in a more environmentally friendly way. Successful drilling operations require blending many technologies. Drilling equipment and procedures have a unique language that must be conquered in order to understand drilling operations.

Working Guide to Drilling Equipment and Operations provides a fundamental, basic knowledge of the intricacies of drilling fluid, drilled solids management, drill bits, drill string design, directional drilling, cementing, casing, hydraulic optimization, and a discussion of predominant problems such as stuck pipe and lost circulation. Background information, such as: clay structure (needed to understand well bore instability and drilling fluids), discussion of pressure and pressure effects, the theory behind factors affecting drilling performance, and rock failure under pressure, are included to enhance the understanding of the drilling process and problems.
