Abstract

See full text

Surfaces of well servicing equipment are treated with both a biofilm remover, which can be a mechanical or chemical, and a biocide composition. The biocide composition is designed to be effective to prevent regrowth of bacteria over a period of time in which the equipment is expected to be out of service. Further, the biocide is compatible with the water source available on site for preparation of the biocide composition. The biofilm remover and the biocide composition can be applied or mixed together as a single treatment, if compatible. The biocide is maintained within the equipment or is displaced therefrom, such as with nitrogen and residual biocide composition is effective therein to prevent regrowth. Nitrogen can be maintained within the equipment until put back into service.
