IN-SITU MICROBIAL OXYGEN GENERATION AND HYDROCARBON CONVERSION IN A HYDROCARBON CONTAINING FORMATION

摘要

A method for in-situ microbial oxygen generation in an underground hydrocarbon containing formation comprises : - injecting into the formation an oxygen generating composition comprising thermophilic chlorate reducing micro-organisms, such as bacteria of the genus Archaeoglobus, Geobacillus and/or Thermus, which multiply at a temperature of at least 60° C; and - inducing the multiplied micro-organisms to convert the hydrocarbons and/or other pore fluid components in-situ into transportable or disposable products
