Oil Enhancement Processes: Chemical Flooding


Main Enhanced Oil Recovery (EOR) methods include chemical, thermal, and miscible processes. Chemical EOR processes have been applied successfully worldwide. This course is designed to provide key aspects of chemical methods plus process limitations. The course covers all chemical methods of polymer, surfactant/polymer, alkaline/surfactant/polymer (ASP) methods plus microemulsion and other chemical techniques. The course also presents technical backgrounds, current status, and future of chemical EOR techniques with field case studies worldwide to screen technical strengths and limitations of these methods. Participants will also learn recent developments and/or chemical advancements that make chemical EOR methods attractive.

Day One

  • Why do we need EOR?
  • Differences and similarities between EOR and IOR

  • Types of EOR methods and possible enhancement approaches
  • Screening criteria for EOR techniques in comparison to chemical ones
  • Phase behavior and important rock and fluid properties for chemical methods
  • Displacement, vertical, and volumetric efficiencies and how to improve
  • Environmental constraints for EOR methods

Day Two

  • Main reservoir concepts for EOR methods
  • Main fluid properties for EOR  methods
  • Polymer types, mobility, properties, calculating polymer injectivity and mechanical degradation, fractional flow of polymer, and elements of designing the flood
  • Case studies of chemical EOR screening, pilot and full field implementation experiences
  • Surfactant-polymer flooding: key aspects, surfactant-brine-oil phase behavior, and performance prediction

Day Three

  • Micellar-polymer (MP) flooding: MP process, high capillary number, designing, non-ideal effects, and how to make a simplified recovery prediction
  • Alkaline-surfactant-polymer (ASP) process: advantages and limitations
