Abstract
This invention provides a process for control in oil and gas wells and related facilities of prokaryote caused souring, fouling and corrosion by reduction of problematic prokaryotes with naturally occurring lysing organisms, particularly sulfate-reducing prokaryotes by proliferating suitable virulent lysing organisms under conditions in which problematic prokaryotes thrive, including in a gas production wellbore. The process provides in situ proliferation of virulent lysing organism in a wellbore by providing both virulent lysing organisms and their host prokaryotes to selectively grow an effective control amount and concentrations of lysing organisms in a well formation.
