Tóm tắt

 A system and method for enhancing the recovery of heavy oil in an oil extraction environment by feeding nutrients to a preferred microbial species (bacteria and/or fungi). A method is described that includes the steps of: sampling and identifying microbial species that reside in the oil extraction environment
  collecting fluid property data from the oil extraction environment
  collecting nutrient data from the oil extraction environment
  identifying a preferred microbial species from the oil extraction environment that can transform the heavy oil into a lighter oil
  identifying a nutrient from the oil extraction environment that promotes a proliferation of the preferred microbial species
  and introducing the nutrient into the oil extraction environment.
