Attendees will receive a comprehensive methodology for well performance analysis with specific focus on unconventional oil and gas in this course. The approach combines the use of several powerful techniques and will illustrate the practical aspects of production data analysis.
Participants are encouraged to bring their own data, as time will be allotted to go through their examples as a class. Depending on interest and time available, examples from Barnett, Bakken, Montney, Horn River, Marcellus, Haynesville, and Eagle Ford plays will be presented. Laptops are required for this course. Course materials will be distributed via USB drive.
