This book provides a theoretical basis and technical support for carbonate acid stimulation design. Carbonate reservoirs are one of the most important sources of fossil fuels. Acid stimulation is an effective technique for enhancing reservoir performance and boosting production. The book stands as a fundamental guide in implementing acid stimulation techniques in carbonate reservoirs. It models the acid stimulation process, contemplating mass, momentum, and energy changes alongside the real mineral composition of the carbonate rock matrix. Comprehensive sensitivity studies are conducted to elucidate the targeted mechanisms and optimization principles for designing acid stimulation applications in carbonate reservoirs. This book also serves as an excellent foundation for numerical simulation, providing detailed descriptions of how finite volume methods and sequential decoupling algorithms are utilized for numerical discretization and solving decoupled solutions on staggered grids. This book is an essential reference for reservoir engineers, academics, and students interested in studying and performing acid stimulation in carbonate reservoirs. It also helps readers obtain an understanding of modeling reactive flow in porous media with coupling multi-physical fields, including hydrologic–chemical-thermal processes and multi-scale characteristics. In addition, this book also delves into scale-up methods, such as the fundamental theoretical foundations and important theorems of the volume averaging approach. The book is used as a textbook for senior undergraduate and graduate courses in petroleum engineering.

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.
