Abstract
A novel process for sustaining microbial activity in subterranean formations which comprises introducing in addition to microbial nutrients, a sequestering anion. 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 more readily transportable due to the presence of a sequestering agent in the formation.
