Decline Curve Analysis - Reserves & Economics for Shale Course

Subscribe View Sample Lesson 16:22 hours

Though there are more sophisticated methods, decline curve analysis is by far the most common. Combined with analysis of the other parts of cash flows, it forms the foundation of acquisitions, drilling programs and all sorts of investment analyses. Nevertheless, its simplicity often misleads its users, and ignorance manifests as expensive mistakes. This course unpacks the science and the practice of decline curve analysis and explores the other aspects of cash flows in a framework designed to result in quality engineering and reliable decisions. Suitable for experienced engineers or, by excluding some of the detailed engineering work, for users looking for an introduction to all of the dynamics that affect the business of oil and gas.
