This book is about the technology of using fluid production or injection and pressure measurement signals from wellbores and relating those signals to the subsurface geology and subterranean reservoir properties. It is aimed at students of well-testing and practicing petroleum engineers or geoscience professionals for subsurface characterization and modeling. The topics include the art and science of well-test analysis, pattern recognition of rate and pressure signals, and a quantitative approach for estimating important subsurface geological parameters for subsurface aquifers and reservoirs containing oil, gas, and geothermal resources. The book is also particularly of value as a guide to asset managers actively developing unconventional reservoirs and CCUS.
An account of responses in wells producing fluids (hydrocarbons, water, steam) from subterranean porous formations. The reference explains the theories forming the basis of procedures for estimating the properties of underground reservoirs, and the underlying assumptions of well test analysis.
Well Test Analysis for Multilayered Reservoirs with Formation Crossflow introduces the fundamentals of well test analysis of a multilayered reservoir with formation crossflow. The effects of reservoir parameters on wellbore pressure and flow rate are examined, as is a proper method that has been established to analyze well test data that leads to better determinations on the reservoir parameters for each layer of the reservoir. Focusing on multilayer models for data analysis, this reference explains the reasons for the existence of single-phase crossflow in multilayer reservoirs, exploring methods to establish them and presenting practical applications to utilize and implement for today's more complex reservoirs. Aiding in better well testing operations and models, this book is a one-stop solution for today's reservoir and production engineer, helping them understand every layer of their reservoir. - Includes real-world examples of well testing through multilayered reservoirs, whether with crossflow or with formation crossflow - Provides strong guidance and criteria of research on reservoir dynamic performance, such as physical models and mathematical models - Includes a new unsteady crossflow model for vertical interference testing in low-permeability zones - Describes interpretation methods for different cases in multilayer reservoirs, including a new model called semipermeable walls for stratified reservoirs, drawdown test procedures and layer-by-layer test procedures that are useful for shales between layers
Oil Well Testing Handbook is a valuable addition to any reservoir engineer's library, containing the basics of well testing methods as well as all of the latest developments in the field. Not only are "evergreen" subjects, such as layered reservoirs, naturally fractured reservoirs, and wellbore effects, covered in depth, but newer developments, such as well testing for horizontal wells, are covered in full chapters. - Covers real-life examples and cases - The most up-to-date information on oil well testing available - The perfect reference for the engineer or textbook for the petroleum engineering student
This is the first part of a two-volume work which comes at a time when oil producers are taking a close look at the economy of oilfield operation and redesign of production technology to improve ultimate recovery. The very high cost, and risk, of the search for new oilfields demands the re-evaluation of production technology and reservoir engineering to improve the production characteristics of existing oilfields.It is the aim of this work that it will be instrumental in the improvement of the global enhancement of oil production and ultimate recovery. It is the outcome of extensive collaboration between experts in petroleum who have devoted their time to the lucid expression of the knowledge that they have acquired through experience in the evaluation and solution of field problems, and development of economic field processes. Oil production companies have been generous in their cooperation through assistance and encouragement to the authors and permission to publish data, designs and photographs.Together, the two books provide a detailed and comprehensive coverage of the subject. The physical and chemical properties of the fluids encountered by engineers in the field are clearly described. The properties, methods of separation, measurement, and transportation of these fluids (gases, condensate liquids derived from natural gas, crude oils and oilfield waters) are dealt with. Following a presentation of the fluids and their process technology, a series of chapters give a thorough discussion of every type of surface equipment that is encountered in the myriad aspects of oilfield operations, ranging from waterflooding to new enhanced oil recovery techniques. Included are all methods for pumping, water control, production logging and corrosion control. The coverage also extends to: well completion and work-over operations, methods for design and operation of underground gas storage, and a review of offshore technology.Surface Operations in Petroleum Production is therefore a comprehensive reference which will be invaluable for field production managers and engineers; as well as being an ideal text on production technology to complement the study of reservoir engineering.
Dynamic Well Testing in Petroleum Exploration and Development, Second Edition, describes the process of obtaining information about a reservoir through examining and analyzing the pressure-transient response caused by a change in production rate. The book provides the reader with modern petroleum exploration and well testing interpretation methods, including their basic theory and graph analysis. It emphasizes their applications to tested wells and reservoirs during the whole process of exploration and development under special geological and development conditions in oil and gas fields, taking reservoir research and performance analysis to a new level. This distinctive approach features extensive analysis and application of many pressure data plots acquired from well testing in China through advanced interpretation software that can be tailored to specific reservoir environments. - Presents the latest research results of conventional and unconventional gas field dynamic well testing - Focuses on advances in gas field dynamic well testing, including well testing techniques, well test interpretation models and theoretical developments - Includes more than 100 case studies and 250 illustrations—many in full color—that aid in the retention of key concepts
The conventional and modern well test interpretation methods are an important tool in the petroleum engineer's toolkit. Used in the exploration and discovery phase of a field, they are performed to determine the quality of a well or to permit estimation of producing rates at different producing pressures. However once a field enters the middle and later development phase, the reservoir flow environment grows increasingly complex and conventional or modern methods do not satisfy the needs of old field development and evaluation. Based on over 10 years of field and research experience, Streamline Numerical Well Test Interpretation Theory and Method provides an effective method for the determination of residual oil distribution for the middle and mature phases of a field. One of the most advanced books available, the author explains the development history of well test theory, analyzes the limitation of modern well test interpretation method, and proposes the concept and framework of numerical well test. This is quickly followed by an introduction of basic principles and solution procedures of streamline numerical simulation theory and method. The book then systematically applies streamline numerical well test interpretation models to a multitude of reservoir types, ranging from single layer reservoir to multi-layer reservoirs. The book presents multi-parameter streamline numerical well test automatic match interpretation method based on double-population genetic algorithm, which lays the foundation to fast automatic match of numerical well test. The book introduces streamline numerical well test interpretation software with independent intellectual property right which is programmed based on the above theoretical studies. - Single and muti-layer sandstone water flooding reservoirs - Multi-layer sandstone chemical flooding model and components - Explains the application of streamline numerical well test and software - Applies programmed software to 177 wells - Quickly calculate the distribution of pressure, saturation and streamline - Covers all kinds of numerical well test interpretation models - Avoid the disadvantages of conventional well test and numerical well test interpretation method - Complete tutorial on streamline numerical well test interpretation software
