Treating wells with self-precipitating scale inhibitor
Patent
·
OSTI ID:6645698
The scaling of a producing well is inhibited by injecting a self-reacting alkaline aqueous solution of a pH-lowering reactant, a compound containing scale-inhibiting anions and a compound containing multivalent cations. The solution subsequently precipitates a slightly soluble scale inhibitor within the reservoir.
