Estimating the term…
The present disclosure relates to isolation, identification and application of Shewanella putrefaciens strain LH4:18 that grows, under denitrifying anaerobic conditions, on crude oil as the sole carbon source. This organism assists in oil release from substrate in reservoir simulations when grown on either lactate or peptone as a carbon source. Shewanella putrefaciens strain LH4:18 can be used alone or in concert with other microorganisms to improve oil recovery.
An isolated microorganism designated as bacterial isolate Shewanella putrefaciens LH4:18 (ATCC No. PTA-8822).
An oil recovery enhancing composition comprising:
A method for improving oil recovery from an oil reservoir comprising:
A method for promoting hydrocarbon bioremediation comprising applying bacterial isolate Shewanella putrefaciens LH4:18 (ATCC No. PTA-8822) to an area contaminated with hydrocarbons.
A method for promoting oil pipeline maintenance comprising applying bacterial isolate Shewanella putrefaciens LH4:18 (ATCC No. PTA-8822) to an oil pipeline.
