The book is focused primarily on characteristics and determinative methods of reservoir orientation, the concept of vector well pattern and corresponding realistic techniques of well pattern deployment, well pattern control principles, Optimum design of well pattern based on the reservoir direction characteristics, and the schemes of well spacing density regulation at different stages of development. The procedures for improving water flooding efficiency have been provided. This book is suitable for reservoir engineering managers, reservoir engineers, and students of petroleum engineering.

The author engaged in the research about the area of reservoir engineering, which is primarily focused on the method of reservoir engineering, reservoir numerical simulation, oilfield development program and optimization and petrleum economic. The author is a member of SPE and Director of the China energy society. Provincial science and technology progress is awarded five times. The 102 paper was published. The characteristics and determining methods of reservoir orientation, the concept of vector well pattern and correspondingly reasonable methods of well pattern deployment was proposed first.
