- 16. What is MEOR by MicroPro? MEOR is an in-situ flooding method using specific micro-organisms that synthesize various products which enhance the oil recovery.
- 17. Classification of EOR - technologies In-situ combustion Steam injection Gas injection Water injection Water injection with: CO2 Detergents Polymer Acids Bacteria (MEOR)
- 18. Costs versus reward for various EOR techniques from: SIMANDOUX et al. (1990) Managing the Cost of Enhanced Oil Recovery. IFT Journal, Vol 1.
- 19. MEOR – Flooding process • Bacterial growth and fermentation process deep inside the oil reservoir • Generation of gases, acids, alcohols and surfactants increasing oil mobility • Enhancement of oil production • Cultivation of bacteria adapted to specific reservoir conditions • Injection of pre-cultivated bacteria and molasses into reservoir • Flooding the reservoir with bacteria and molasses
- 20. Effects of Microbial Enhanced Oil Recovery Adds energy due to injection of molasses and in-situ biogas formation Changes the pressure potential in fissures and pores Decreases the viscosity of oil by increasing volume and hydrogenization Changes the surface tension regime (oil/water) Improves the capillary adsorption of all liquids Increases the permeability by bringing in fresh matrix through rock solution
- 21. Microbial insitu activities - Biogas - Microbial products Changes Oil field parameters CO2 (80 %), H2 (20 %) up to 380 ml per gram of molasses Increases pressure up to 20 bar in model experiments Leading to a higher energy potential in the oil field CH4 as final product from organic acids, alcohols and hydrogen Increases the oil volume factor and therefore decrease the oil viscosity Resulting in better oil mobilization Changes pressure potential in fissures and pores Increasing oil production rate
- 22. Microbial insitu activities - Organic acids - Microbial products Changes Oil field parameters Acetic-, propionic-, nutyric- and valerianic acid Decrease pH down to 4.8 Increasing rock permeability Dissolve carbonate rock by about 0,2 tons of rock per ton of molasses, Adding new parts to fissure system not yet drained Building up new flow pathways
- 23. Microbial insitu activities - acetone and alcohol's - Microbial products Changes Oil field parameters Methanol, ethanol, propanol, butanol decrease interfacial tension (for example against heptane up to 12 - 46,5 mNm-1) Forces imbibition of injected molasses media into pore canals and fissures, Biolipids Alter rock wettability Releasing more oil from the rock by breaking up oil/water

- 38. Results from MEOR field test at „Romaschkino“ Intensive microbial in-situ production of CO2, H2, organic acids, alcohols and surfactants have been verified under field conditions. The decrease of water content from 80% to 60% doubled the oil production. The lowering of the oil viscosity and the water content, and the increase of the gas/oil ratio, led to an increase of daily total fluids production rate by about 50%, resulting in: increased oil production by more than 250% for an additional cost for MEOR of about 3,5 $/bbl
