Method for preventing hydrogen sulfide formation |
| abstract |
Hydrogen sulfide present in an aqueous system is removed and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing into the system nitrite and nitrate and/or molybdate ions, whereby denitrifying microorganisms outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide and the nitride along with the denitrifying microorganisms remove hydrogen sulfide already present in the system. The system which contains the denitrifying microorganisms and which is essentially free of hydrogen sulfide can enhance oil recovery by means of a microbial enhanced oil recovery mechanisms. |
