_Development Theories and Methods of Fracture-Vug Carbonate Reservoirs_ explores the theories and methods for successful development of a fracture-vug reservoir by presenting the developmental strategies used in the Tahe oilfield. Some of the theories and methods of developing the Tahe fracture-vug reservoirs have been inspired by two China national research projects: The ‘Basic research on development of fracture-vug carbonate reservoirs’ (2006-2010), and the ‘Basic research on production mechanism and oil recovery enhancement of fracture-vugcarbonate reservoirs’ (2011-2015), with support by the National Basic Research Program of China. These theories and methods have facilitated the successful development of the fracture-vug reservoir in the Tahe oilfield, providing effective technologies and inspirations to developing similar reservoirs everywhere. * Provides information on both theoretical developments and technological innovations * Applies the modern karst formation characterization and the fracture-vug hierarchical structure to geological investigations of fracture-vug carbonate reservoirs * Introduces the karst facies-controlling 3D geologic modeling of fracture-vug reservoir formations * Proposes the coupled-processing and equivalent multi-medium numerical simulation methods of fracture-vug reservoirs * Presents development methodologies and techniques of water/gas flooding
