This book presents the authors' research findings on the dynamics of oil migration, research methodologies, insights and applications in petroliferous basins. It studies the behaviors of oil migration in porous media through physical experiments and numerical simulations, explores the mechanism of oil migration and effects of migration process, and then establishes a migration modeling method by coupling the source, driving forces and carriers. The new method can be used to estimate the amount of migrated hydrocarbons and then predict the location of possible hydrocarbon accumulations in different parts of a basin. This approach is useful for resources assessment and prediction of the distribution of hydrocarbon accumulations. An example utilizing this methodology is presented to study the dynamics of migration and accumulation processes in the southern slope of Dongying Depression in Bohai Bay Basin in China. The book appeals to scientists and professionals working on petroleum prospecting as well as faculty and students in petroleum geology.
