  • Metal Sulfide Scale Dissolver For Oilfield Application
    Publication number: 20250075338
    Abstract: A method may include providing a treatment fluid comprising a metal sulfide dissolver and a base fluid. The metal sulfide dissolver includes a chelating agent, a boosting agent, and a dispersing agent. The treatment fluid is then injected to contact a metal sulfide scale, which dissolves at least partially. The treatment fluid may be injected into a wellbore as a standalone treatment or as an additive.
