While the primary objective of the course is to prepare reservoir engineers and/or petroleum engineers to utilize existing tests’ results and well/reservoir performance data, it will be invaluable to those who face the responsibility of formulating EOR programs for green and brownfields alike. The potential savings by avoiding expensive and time-consuming programs render to unreliable or questionable outcomes are tremendously significant! Therefore, attending this course should be mandatory for all who deal with screening, processing, and analyzing CCA/SCA data for EOR/IOR purposes.
