Production data analysis & DCA (Tools: OFM / Ecrin: Topaz)

What you’ll learn Upon completion of the course, participants will be able to:

• apply the fundamental concepts of decline curve analysis and Arps decline curves analysis for reserves evaluation during boundary dominated flow regime,
• apply Fetkovich decline curves analysis and related type curves and assess the effects of transient regime,
• discuss principles of Blasingame decline curves analysis and related advantages by respect to Arps & Fekovitch decline curves analysis.

Course Description This course begins with a brief description of the theory of decline curve analysis and its background. Both type-curve fitting and type curve matching techniques will be explained and demonstrated. The more common type curve fitting methods are demonstrated using examples from fields. The class includes a variety of hands-on problems, and exposure to modern computer-based decline analysis tools. Who this course is for: Engineers or technical assistants who are responsible for making forecasts of future production using decline curves analysis. Economists, managers, or geoscientists who are interested in developing a greater working knowledge of decline curve methods and how to make better forecasts will also benefit from this course.   Course Content
