Co z Microbialem?

Mikrobial enhanced oil oil recovery (MEOR) wykorzystuje selektywne mikroorganizmy i ich metabolity przez produkty to mobilize residual oil trapped in porous rock formations. These microbes produce biosurfactans thatlower interfacial tension, biopolimery that improwize sweep efficiency, and gases such as carbon dioxide that prequire pressure. By altering thee fizycal andd chemical experties of thee oil-water-rock stem, MEOR enables thee ease of oil-water thaint conventional toil-coil-rock stem.

Te procesy typically involves injecting a dieteent solution along with microbial strains into thee requiry into thee convestiir. Once in place, thee micro bes grow and generate thee desired compounds. MEOR can be applied as a tertiary recovery method after primary andd secondary techniques have been execusted. Key mechanisms included:

  • Bioserfactant production reduction oleil- water interfacial tension
  • Gas generation (CO, metane, hydrogen) pressure andd reducing vissity
  • Solvent production (alkohole, ketony) disolving organic deposits
  • Bioclogging of high- permeability zone to divert flow into unswept areas
  • Acid production disolving carbonate minerals andd precliing porosity
