Unplugging brine-submerged perforations
Patent
·
OSTI ID:5616046
Fluid passageways between a well borehole and a subterranean reservoir which are both plugged and submerged within relatively dense brine can be contacted with heat and oil solvent by arranging a nitrogen gas generating aqueous solution to be both reactive at the reservoir temperature and density than the brine in the borehole and flowing alternating slugs of it and a liquid oil solvent into the zone to be treated.
