Enriched steady state microbial consortiums for microbial enhanced oil recovery and in situ bioremediation of hydrocarbon-contaminated sites, under anaerobic denitrifying conditions, are disclosed.

Steady state anaerobic denitrifying consortium for application in in-situ bioremediation of hydrocarbon-contaminated sites and enhanced oil recovery

Chemical compounds that are N-lauroyl amino acids or derivatives thereof were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal.

Oil release with N-lauroyl amino acid-based compounds

Methods and compositions are provided wherein microorganisms are used to alter the interface of hydrocarbons and hydrocarbon-coated surfaces to increase oil recovery, for improved bioremediation and/or pipeline maintenance.

Altering the interface of hydrocarbon-coated surfaces

The present disclosure relates to developing an enriched steady state microbial consortium capable of modifying crude oil components of an oil reservoir under anaerobic denitrifying conditions. The steady state consortium may be used to improve oil recovery.
