ABSTRACT:
The present invention is a phosphate compound for use in a bacterial nutrient medium. The medium is injected downhole in a petroleum formation along with a bacteria (or its spore) and provides the bacteria with growth nutrients. The nutrient solution contains a phosphate compound which: will not precipitate out of solution under ambient conditions; will chelate alkaline earth, rare earth, transition and heavy metal ions; and provide a nutrient source for the bacteria.
