Prevention™ corrosion inhibitor is a film-forming amine that protects metal surfaces from corrosion in divalent brine fluids, such as Newpark’s proprietary Fusion™ drilling fluid system. The Fusion system is a uniquely formulated brine system that uses advanced fluid engineering to increase bit life, improve lubricity and manage corrosion.
- Protects tubing and casing strings
- Provides over 90% corrosion inhibition
- Stable and effective in high divalent brines
- Does not offset drilling fluid properties
Prevention corrosion inhibitor protects tubing and casing strings from corrosion associated with acid gas and inorganic salt attack when divalent ions such as calcium exceed a critical concentration. Conventional, sulfite-based corrosion inhibitors lose effectiveness as divalent ion concentrations increase. Prevention corrosion inhibitor reaches optimal performance when divalent ions exceed approximately 40,000 ppm. Prevention corrosion inhibitor works synergistically with Reaction™ scale inhibitor and Reduction™ oxygen scavenger in protecting metal surfaces from corrosion when drilling with divalent brine systems. It is water soluble and effective for use in divalent salt saturated water-based drilling fluids, solids-free brines and packer fluids. Prevention corrosion inhibitor is effective up to 150°C in calcium and zinc brines and is effective in low concentrations.
Prevention corrosion inhibitor is added to the system at a concentration of 3-10 L/m3. A maximum pH of 10.5 is recommended for optimal effectiveness.
