Assisted oil recovery with use of fermentation fluids |
| abstract |
An aqueous composition is provided, suitable for direct use in waterflood oil recovery processes, which comprises the clarified fermentation fluid obtained by (a) culturing a polysaccharide-producing microorganism in an aqueous culture medium to produce an aqueous culture containing dissolved polysaccharide therein; and (b) clarifying the resultant aqueous culture from (a) by at least one of centrifugation and filtration, introducing therein at least one bactericidal agent, and recovering the resultant clarified fermentation fluid; said aqueous composition being obtained without precipitation and recovery of a solid polysaccharide and dissolution thereof in an aqueous medium. The above composition can be pumped into oil formations without substantial clogging thereof. |
