Reservoir Surveillance Course
Introduction:
The modern-day reservoir management process involves goal setting, planning, implementation, monitoring, evaluation, and revising plans. It requires a clear understanding of the alternative mechanisms of oil recovery and the tools available to predict reservoir performance under alternative exploitation plans. Proper management requires the early diagnosis of anomalous performance and the evaluation of alternative remedial options. In order to select the best plan, the profitability of the alternative plan has to be established. This course is oriented towards the selection, implementation, monitoring and updating exploitation plan for better reservoir management. It presents sound reservoir management concepts and methods including a team approach based on the integration of geoscientific and engineering professionals, tools, technology, and data.
