Reserve Estimation and Risk Analysis


Candidates:

Geoscientists, engineers or managers involved in preparing or utilizing reserve estimates.

Summary:

The course includes lectures and practical problem solving and covers the bases for estimation and classification of oil and gas reserves at different risk areas. It aims to present a simple yet powerful method for evaluating the geologic (and economic) chance, volume, value and efficiency associated with exploring in different geologic plays. The methodology is applicable for a spectrum of opportunities, from a medium sized concession to a full geologic play.
