CONQOR 303A Brine-Soluble Filming Amine | Schlumberger

CONQOR 303A

Brine-soluble filming amine

Conqor 303A inhibitor helps prevent general corrosion attack on casing, tubing and downhole tools in contact with clear completion brines.

Applications

Conqor 303A additive controls corrosion of tubing and casing strings when used in workover or packer brines, including sodium chloride, calcium chloride, sodium bromide, and calcium bromide. Conqor 303A corrosion inhibitor 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.

For treatment of clear brine fluids, one 55-gal (208-L) drum of Conqor 303A corrosion inhibitor should be added to 100 barrels (15.9 m3) of brine. This is equal to 0.55 gal/bbl (13.1 L/m3). Conqor 303A corrosion inhibitor can be added directly to the brine without special mixing equipment or agitation.

Typical Physical Properties

  • Physical appearance: Dark brown liquid
  • Specific gravity: 1.03-1.05
  • Flash point: 305°F [151.6°C] (PMCC)
  • Pour point: <11 degF>
  • Viscosity at 77 degF [25 degC]: 4 cP

Advantages

  • Protects metal surfaces in both the shallow, upper part of the well and in the deeper, hotter areas. At the recommended concentration, Conqor 303A corrosion inhibitor provides protection at bottomhole temperatures up to 350°F [177°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, and calcium bromide

Limitations

  • Designed for application in clear brine fluids. If used in a viscosified completion or drilling fluid, pilot testing for compatibility is recommended.

Toxicity and Handling

  • Bioassay information is available upon request.
  • Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the Material Safety Data Sheet (MSDS).

Packaging and Storage

  • Conqor 303A corrosion inhibitor is packaged in 55-gal (208-L) drums.
  • Store in a dry, well-ventilated area. Keep container closed. Keep away from heat, sparks and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and/or stacking.
