Product Information

HDC®-3 is Well Flow’s most powerful barite-dissolving chemical. The rate at which HDC®-3 dissolves barite increases with temperature up to 400°F, and 450°F is the practical limit for HDC use. It has been confirmed through independent laboratory tests to dissolve 180 grams/liter or more of drilling-grade barite and more than 350 grams/liter of strontium and magnesium sulphate.

HDC®-3 also dissolves all sulphate scales and minerals as well as removes oil-based and water-based mud filter cake in open holes and perforations. Combined with Koplus® LX as spearhead (pre-flush), it is an excellent stimulation choice for sandstone formations.
