Enhancement Oil Recovery Methods; Theory and Application

Enhancement Oil Recovery Methods; Theory and Application

Course Description

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 brown fields 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 to all who deal with screening, processing and analyzing CCA/SCA data for EOR/IOR purposes.

Learning Outcomes: 

  • Analyze and evaluate reported relative permeability curves and make necessary tuning and fine-tuning 
  • Relate CCA/SCA results to rock typing and reservoir characterization 
  • Formulate efficient CCA/SCA program for a new well or reservoir 
  • Screen methods of EOR based on clear criterion 
  • Examine, evaluate, monitor, modify and update selected EOR technology on regular basis
