A process includes growing NRB in a nitrate reducing bacteria media to form a NRB culture and combining the NRB culture with a concentrated nitrate solution to form a NRB composition.

Composition and method for controlling bacteria in formations

Systems, compositions, and methods for synergistic additives for use in the scavenging of sulfur-containing compounds encountered in oilfield operations are provided. In one embodiment, the methods comprise injecting a sulfide scavenging additive that does not comprise a significant amount of an aldehyde into at least a portion of a subterranean formation where one or more sulfur-containing species are present; and injecting a synergistic additive comprising at least one base into at least the portion of the subterranean formation.

Synergistic sulfide scavenging additives for use in oilfield operations

A process includes injecting a molybdate or molybdate salt into a hydrocarbon-bearing formation, wherein no biocide is injected into the formation.

Method for controlling bacteria in formations using molybdate

A method of controlling sulfides in water systems is disclosed which includes injecting 9,10 anthraquinone into the water system and injecting a nitrate or nitrite into the water system.
