Drilling Starch
Â
Drilling Starch is a high-quality grade of pre-gelatin starch that is widely used in water-based mud systems to minimize fluid loss and forming thin filter-cake in wellbore surface. Drilling Starch is a non-ionic natural polymer which may be used in low-saline to high-saline waters. It meets API 13 A specifications.
