Key objectives of this course are to learn various compliant methods of preparing reserves estimates, learn to estimate and understand the impact of economics on those estimates, and properly classify those reserves using the current reserves definitions. Recent case studies, SEC audit questions, and class problems are used extensively to develop an understanding of those skills and include ethical issues that arise when calculating and reporting reserves. One personal computer is provided, at additional cost, for each two participants.


"I like how everything was clear and organized! Also how the instructor was so helpful and ready to answer any question and explain any un-understood topic." - Participant, Kuwait
