Abstract: The present invention provides a method of injecting nutrients into a subterranean formation in order to achieve a desired in-situ microbial objective. Sources of individual nutrient components which are deficient in the formation are sequentially injected so that a complete nutrient medium capable of sustaining substantial microbial activity is formed in the formation upon injection of the last of said sources. Said sources are preferably injected into the formation in order of decreasing quantitative formation retainability.
