Injection of scale inhibitors for subterranean microbial processes

摘要

A novel process for sustaining microbial activity in subterranean formations which comprises introducing as a microbial nutrient, a scale inhibitor. This process may include the sequential injection of sources of individual nutrient components which are deficient in said subterranean formation, whereby the injected phosphorus source is selected from the group consisting of an organic phosphate and an organic phosphonate.
