Presenting new and exact analytical solutions to complicated reservoir flow problems involving fractures, shales and faults, this book provides fast, stable methods for numerical simulation useful in infill drilling and formation evaluation. Mathematical studies of artificial viscosity effective properties, stochastic modeling, grid generation, time lapse logging and other special topics of current interest to reservoir engineers, well test analysts and petroleum engineering students are discussed.
