Use of potassium hydroxide solutions in a well bore
Patent
·
OSTI ID:6106129
A workover fluid, a kill fluid, or completion fluid having potassium hydroxide dissolved therein is injected into a well bore penetrating and communicating with a subterranean sandstone formation containing water-sensitive fine particles, including clays, and invades the sandstone formation. Potassium hydroxide contacts and stabilizes the fine particles for a substantial period of time thereby substantially preventing formation permeability damage caused by encroachment of aqueous solutions having a distinct and undesired ionic constituency.
