C02 Corrosion Inhibitor

Typical Physical Properties:

• Physical Appearance: Dark brown oily liquid
• Specific Gravity: 1.*5
• Flash Point: **5°F (**1.6°C) (PMCC)
• Pour Point: <*1°F (**2°C)
• Viscosity at *7°F (*5°C): **1 CP

Applications: Morpholine additive controls corrosion of tubing and casing strings when used in workover or packer brines, including sodium chloride, calcium chloride, sodium bromide, calcium bromide, and zinc bromide. It is designed for use in clear brines but can be used in viscosified completion or drilling fluids. Pilot testing for compatibility is recommended for this application. Works at a wide range of temperatures up to **6°F (**0°C).

For treatment of clear brine fluids, one **-gal (***-L) drum of RWE-CIMO corrosion inhibitor should be added to **0 barrels (*5.9 m³) of brine. This is equal to 0.*5 gal/bbl (*3.1 L/m³) or 5 lb/bbl (*4.3 kg/m³). Morpholine corrosion inhibitor can be added directly to the brine without special mixing equipment or agitation.

Advantages:

• Protects metal surfaces in both the shallow, upper part of the well and in the deeper, hotter areas. At the recommended concentration, RWE-CIMO corrosion inhibitor provides protection at bottomhole temperatures up to **6°F (**0°C).
• Protects both tubular goods and completion tools exposed to workover or clear completion brines.
• Compatible with sodium chloride, potassium chloride, calcium chloride, sodium bromide, calcium bromide, and moderate-density zinc bromide brine fluids.
