Three stages of Reservoir Management

• Natural depletion/Primary Recovery — oil is forced out by pressure generated from gas present and/or water aquifer
• Increased Oil (IOR) /Secondary Recovery — water or gas injection to maintain reservoir pressure
• Enhanced Oil Recovery (EOR) /Tertiary Recovery — inject fluids that reduce viscosity and improve flow:
  • Carbon dioxide
  • Steam, air or oxygen
  • Polymer solutions
  • Gels
  • Surfactant-polymer formulations
  • Alkaline surfactant-polymer formulations
  • Microorganism formulations
