Book Description
This book provides a succinct overview on the application of rate and pressure transient analysis in unconventional petroleum reservoirs. It begins by introducing unconventional reservoirs, including production challenges, and continues to explore the potential benefits of rate and pressure analysis methods. Rate transient analysis (RTA) and pressure transient analysis (PTA) are techniques for evaluating petroleum reservoir properties such as permeability, original hydrocarbon in-place, and hydrocarbon recovery using dynamic data. The brief introduces, describes and classifies both techniques, focusing on the application to shale and tight reservoirs. Authors have used illustrations, schematic views, and mathematical formulations and code programs to clearly explain application of RTA and PTA in complex petroleum systems. This brief is of an interest to academics, reservoir engineers and graduate students.

Book Description
Rate-transient analysis (RTA) is now one of the most important methods for reservoir and hydraulic fracture characterization used in the petroleum industry for unconventional gas and light oil reservoirs. RTA is also used as the basis for generating a production forecast. However, RTA is based primarily on analytical models that were developed for conventional reservoirs with many simplifying assumptions that often don't apply to unconventional reservoirs. Unconventional Gas and Light Oil Reservoir Rate-Transient Analysis: Volume 1 - Fundamentals delivers a critical knowledge gap to help practicing reservoir and production engineers understand the unique differences in rate-transient analysis for today's unconventional reservoirs. Starting with the fundamentals, engineers first understand the basic flow regimes and analysis methods along with the unique reservoir properties of unconventional assets. Then, the chapters progress to more advanced topics such as how to modify and apply RTA methods for each instance of shale oil/gas, coalbed methane, and tight shale oil/gas along with transforming these modified methods into higher quality production forecasting, with emphasis on analytical and semi-analytical methods. Supported by many real-world field examples covering both hydraulic fracturing and unconventional reservoirs to learn from with questions and answers to practice, Unconventional Gas and Light Oil Reservoir Rate-Transient Analysis: Volume 1 - Fundamentals supplies today's petroleum engineers with a more intelligent approach to today's more complex reservoirs. Improve reservoir flow-rate workflows specific to unconventional oil and gas reservoirs as well as complex hydraulic fracturing projects Authored by leading researcher and expert in unconventional reservoir RTA Generate stronger production forecasts with guidelines and field examples on how to deal with data uncertainties, poor data quality, and operational upsets

Book Description
Reservoir Engineering of Conventional and Unconventional Petroleum Resources is a practical guide and handbook for engineers and geoscientists. It is also a complete textbook for teaching of reservoir engineering courses with exercises in each chapter. The sources and applications of basic rock properties are presented. Prediction of PVT properties from correlations and equations of state, and laboratory measurements of same properties from fluid samples are discussed. These basic data are applied in material balance analyses, volumetric calculation of hydrocarbons-in-place and reserves, and analyses of reservoir performance using case histories. Production forecasts for conventional and unconventional reservoirs using Arps' decline equations in decline curve analyses (DCA) are presented. The applications of modified Arps' decline equations coupled with transient flow models in rate transient analyses (RTA) are illustrated. Dr. Ezekwe presents fundamental equations and methods for pressure transient analysis (PTA) for fractured and unfractured wells in conventional reservoirs. This is accompanied with well test analyses in unconventional reservoirs using diagnostic fracture injection tests (DFIT). Secondary recovery methods focused on waterflooding, gasflooding, and low salinity waterflooding are demonstrated. Enhanced oil recovery methods are discussed. Dr. Ezekwe recommends experience-based practical procedures for geologic modeling, reservoir characterization, reservoir simulation, and reservoir management. Fundamental economic decision criteria including profitability index, net present value, rate of return are demonstrated with examples.

Book Description
Traditional well logging methods, such as resistivity, acoustic, nuclear and NMR, provide indirect information related to fluid and formation properties. The “formation tester,” offered in wireline and MWD/LWD operations, is different. It collects actual downhole fluid samples for surface analysis, and through pressure transient analysis, provides direct measurements for pore pressure, mobility, permeability and anisotropy. These are vital to real-time drilling safety, geosteering, hydraulic fracturing and economic analysis. Methods for formation testing analysis, while commercially important and accounting for a substantial part of service company profits, however, are shrouded in secrecy. Unfortunately, many are poorly constructed, and because details are not available, industry researchers are not able to improve upon them. This new book explains conventional models and develops new powerful algorithms for “double-drawdown” and “advanced phase delay” early-time analysis - importantly, it is now possible to predict both horizontal and vertical permeabilities, plus pore pressure, within seconds of well logging in very low mobility reservoirs. Other subjects including inertial Forchheimer effects in contamination modeling and time-dependent flowline volumes are also developed. All of the methods are explained in complete detail. Equations are offered for users to incorporate in their own models, but convenient, easy-to-use software is available for those needing immediate answers. The leading author is a well known petrophysicist, with hands-on experience at Schlumberger, Halliburton, BP Exploration and other companies. His work is used commercially at major oil service companies, and important extensions to his formation testing models have been supported by prestigious grants from the United States Department of Energy. His new collaboration with China National Offshore Oil Corporation marks an important turning point, where advanced simulation models and hardware are evolving side-by-side to define a new generation of formation testing logging instruments. The present book provides more than formulations and solutions: it offers a close look at formation tester development “behind the scenes,” as the China National Offshore Oil Corporation opens up its research, engineering and manufacturing facilities through a collection of interesting photographs to show how formation testing tools are developed from start to finish.

Book Description
"Pressure Transient Analysis: Pressure Derivative" provides alternatives to software to make interpreting pressure transient tests easier. This practical reference is written for practicing engineers and students familiar with fundamentals of data acquisition and basic objectives of common pressure tests but challenged when using commercial software and concepts involving pressure derivative. Several commercial software licenses for interpreting pressure transient tests are available; most too advanced for beginning engineers. Many practicing engineers and students use them without understanding fundamental concepts needed to analyze the test. This valuable text focuses on applications of pressure and derivative data for interpretation of pressure transient tests, offering alternatives to costly commercial software. Building from basics, this practical text spans: wells near single and multi-boundary systems, hydraulically fractured wells, naturally fractured reservoirs, interpretation of interference and pulse tests, gas well test analysis (including sources of emissions and decarbonizing strategies, geological sequestration, CCS risks and stress on CCS), multiphase flow, injectivity and falloff tests, rate transient and multi-rate tests, partially penetrated / perforated vertical and slanted wells, and horizontal wells in conventional and unconventional reservoirs - all with emphasis on application of pressure and derivative data to interpret pressure transient tests. Many techniques and equations presented in this book can be found in the black box of commercial well-test analysis software packages - this practical text unlocks, unpacks, and makes critical, analytical tools accessible to core users. "Pressure Transient Analysis" offers students and engineers the basics and tools needed to compute and interpret pressure transient tests without relying on commercial well-test analysis software. The book explains well-test and pressure derivative basics and supplies the step-by-step approach students and engineers need to calculate and analyze pressure transient test results without requiring expensive computational software. Packed with simulated exercises, global field cases, and unsolved problems to reinforce learning, this indispensable text can also be used as a primer on basic concepts of the pressure derivative in conjunction with or before using software.

Book Description
Pressure Transient Testing presents the fundamentals of pressure-transient test analysis and design in clear, simple language and explains the theoretical bases of commercial well-test-analysis software. Test-analysis techniques are illustrated with complete and clearly written examples. Additional exercises for classroom or individual practice are provided. With its focus on physical processes and mathematical interpretation, this book appeals to all levels of engineers who want to understand how modern approaches work. Pressure transient test analysis is a mature technology in petroleum engineering; even so, it continues to evolve. Because of the developments in this technology since the last SPE textbook devoted to transient testing was published, we concluded that students could benefit from a textbook approach to the subject that includes a representative sampling of the more important fundamentals and applications. We deliberately distinguish between a textbook approach, which stresses understanding through numerous examples and exercises dealing with selected fundamentals and applications, and a monograph approach, which attempts to summarize the state-of-the-art in the technology. Computational methods that transient test analysts use have gone through a revolution since most existing texts on the subject were written. Most calculations are now done with commercial software or by spreadsheets or proprietary software developed by users to meet personal needs and objectives. These advances in software have greatly increased productivity in this technology, but they also have contributed to a "black box" approach to test analysis. In this text, we attempt to explain what's in the box, and we do not include a number of the modern tools that enhance individual engineer productivity. We hope, instead, to provide understanding so that the student can use the commercial software with greater appreciation and so that the student can read monographs and papers on transient testing with greater appreciation for the context of the subject. Accordingly, this text is but an introduction to the vast field of pressure transient test analysis.
