This is the fourth volume in a series of books focusing on natural gas engineering, focusing on two of the most important issues facing the industry today: disposal and enhanced recovery of natural gas. This volume includes information for both upstream and downstream operations, including chapters on shale, geological issues, chemical and thermodynamic models, and much more.Written by some of the most well-known and respected chemical and process engineers working with natural gas today, the chapters in this important volume represent the most cutting-edge and state-of-the-art processes and operations being used in the field.  Not available anywhere else, this volume is a must-have for any chemical engineer, chemist, or process engineer working with natural gas.There are updates of new technologies in other related areas of natural gas, in addition to disposal and enhanced recovery, including sour gas, acid gas injection, and natural gas hydrate formations.Advances in Natural Gas Engineeringis an ongoing series of books meant to form the basis for the working library of any engineer working in natural gas today.  Every volume is a must-have for any engineer or library.
