This book considers the “Advanced Production Decline Analysis and Application” by way of manual matching for a vertical well centered in a closed circular reservoir. The book thoroughly discusses several production decline methods, such as Arps, Fetkovich, Blasingame, Agarwal-Gardner, Normalized Pressure Integral (NPI), Transient, Long-term Linear Flow, and Dynamic Material Balance, based on the APDA concepts. It introduces the principles, processes, cases, and applications of these methods.
The “Advanced Production Decline Analysis and Application” book also details the plotting and analysis of APDA curves for complex reservoirs, including closed circular composite reservoirs, two-layered reservoirs, and dual-porosity reservoirs. In the appendix, it presents the theoretical curves of the Blasingame method and the calculation procedure for the normalized pseudo-pressure of gas wells. This information aids readers in understanding the plotting of type curves and the inner workings of analysis software.
Accordingly, this book is a relatively complete and systematic work concerning advanced production decline analysis for oil and gas wells. This book integrates the author’s achievements and experience in his long-term research, so it is meaningful both theoretically and practically. Its publication will be helpful to the promotion and application of APDA, thereby further identifying the performance variation of oil and gas fields and enhancing the field development. Besides, it will have positive and significant effects on the development of reservoir engineering personnel.
