A series of articles intended to introduce geologists to reservoir engineering concepts and their application in the areas of Corporate Reserve Evaluation, Production, Development,
and Exploration. Topics covered in the series are Reservoir Engineering Overview, COGEH Reserve Classifications, and Volumetric Estimation. The format for each article will be to
generally introduce the concept(s), discuss the theory, and illustrate its application with an example.
COGEH, the Canadian Oil and Gas Evaluation Handbook, Reserve Classifications provide a Canadian standard reference methodology for estimating reserve volumes according to reserve and resource
category. There have been many recent changes in an attempt to achieve a “global standard” in order to ensure the public release of accurate, understandable reserve and resource estimations
and classifications.
