Drilling Starch HT
Drilling Starch HT is a high-quality grade of pre-gelatin starch that is used in water-based mud systems to minimize fluid loss and forming thin filter-cake in wellbore surface in high temperatures. High Temperature Drilling starch is a non-ionic natural polymer which may be used in low-saline to high-saline waters. High temperature starch is environment-friendly and easily removeable by acids or oxidizers.
