ABSTRACT:
Processes for effecting biocidal activity in subterranean oil and gas wells being drilled, completed, worked over or produced are described. In general the process comprises blending with aqueous well fluid a biocidally-effective amount of a sulfamate stabilized, bromine-based biocide. Compositions comprised of aqueous well fluid blended with such aqueous biocides are also described.
