MEOR - Step by step

Review of existing reservoir data

  • Evaluation of geologic and geophysical data
    • Reservoir rock type, structure, thickness, porosity, permeability
    • Oil/water saturation
    • Mineral facies/ chemical composition
  • Fluid and gas characteristics
    • Chemical composition of oil, gas, water
    • Oil viscosity, density under reservoir conditions
    • Gas- oil; gas-water ratio, water cut
  • Deposit evaluation
    • OOIP - prognosis of deposit and single wells of interest, decline rate
  • Oil field configuration
    • Number and positions of production and injection wells
    • Injection rates

Chemical and microbiological investigations

  • Existing bacterial population in oil field system:
  • Chemical composition of reservoir water
  • Specification of adaptation program of MEOR bacteria to specific field conditions

Customization of MEOR to specific field conditions

  • Characterization and selection of MEOR microbes
  • Adaption of selected microbes to field conditions
  • Optimization of nutrient media
  • Analysis of bio-products with original sample material
  • Process engineering - scale up

Economic and technical evaluation of MEOR under simulated field conditions

  • Core flooding tests under reservoir conditions to simulate the MEOR drainage
