CONQOR 303A

Corrosion inhibitor for saturated salt water-based muds

CONQOR 303A is a modified brine-soluble filming amine used as a corrosion inhibitor in saturated salt systems water-based drilling fluids. 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, calcium bromide and zinc bromide. CONQOR 303A corrosion inhibitor is designed for use in clear brines, but is applicable in viscosified completion or drilling fluids. Pilot testing for compatibility is recommended for this application. CONQOR 303A 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, 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, calcium bromide and moderate‐density zinc bromide brine fluids.
