COR-SCAV STICKS are primarily used in oil and gas production operations where wells have been depleted of their production and are to be plugged and abandoned. In many cases these wells have untreated water pumped down the annulus as a purging agent. This water over long periods can cause degradation of the metal surfaces down hole, therefore causing loss and or leakage of fluids. The high concentration of both products in stick form when added down hole to the fluids will form a strong organic film on the metal surfaces and absorb the free oxygen in the fluids to prevent corrosion attack to the metal surfaces. The combination of products and its surface activity will also eliminate the environment for anaerobic bacteria growth.
