Well Logging for Reserves and Prospects Evaluation


Objectives :

Well logs interpretation needs to be used as routine data by geologists working in the O&G industry to understand well results, to assess rough evaluation of reserves, to explain well failures and to accurately evaluate new prospects. The course cover the cutting-edge well logging principles and its application in Exploration. It will bring many industry examples and applications to complete university academic courses.
