n: The process that drilling fluid is pumped from annular and reverses out from drill pipe. This method is fast than direct flushing.

abbr: best-available control technology.

n pl: a large, widely distributed group of typically one-celled microorganisms. See anaerobic bacteria, sulfate reducing bacteria.

n: Refers to the microbe that makes drilling fluid decrease filtration rate and viscosity due to it can destroy amylum additive.

n: The process that superpolymer is destroied by the microbe and macromolecule fractures to micromolecule.

breaking down alkanes by bacterial action. Common by psedomonis and ultramonis bacteria and other bacterial strains that digest parts of the crude oil structures. Useful for remediating oil spills or tank bottom residuals.

reactions involving aerobic decay, organic matter oxidation, fermentation, anaerobic decay, etc.

liquefaction or break down of oily waste or clean-up of oil spills by the use of the naturally occurring oil consuming bacteria, chiefly ultramonis and pseudomonis.

n: anything that destroys bacteria.

n: The additive used to kill the bacterias in drilling fluid.

a product that kills bacteria in the water or on the surface of the pipe.

n: The operation that is hard to fish due to the complicated wellbore or fishing.

n: oil that contains a sufficient amount of sediment and water to make it unaccetable to a pipeline or other oil transportation system.

n: See broken formation.
