Drilling starch is a polymer derived from the unmodified starch including amylopectin content. This starch has fermentation stability and it gives enhanced high temperature fluid loss performance when working in combination with drilling fluids. It has optimal use in all water-based drilling, stimulation, and completion fluids.
Usage:
-Apt for drilling, work over or completion of fluid
leakage
- Control additive appropriate for utilization at high
temperatures
- Keep up liquid loss control at up to 300F (150C),
helps in stabilising rheology
- Does not ferment Treatment rate, Typical, 1-4 ppb,
as essential to control liquid loss.
- Higher temperatures (above 150C) may be
necessary to activate HT Starch to supply effective
rheology and fluid loss control totally as a binding
agent.

Drilling starch is non-ionic corn, tapioca based polymers for use in all water-based drilling, completion and stimulation fluids. Drilling starch is extensively used as an additive to prevent the seepage of soil filtrates into the wells in all types of water based drilling fluid systems by increasing the viscosity of the drilling mud and reducing the fluid loss by sealing the walls of the Borehole. High quality biocide added to resist against bacterial and enzymatic degradation.

Pregelatinized starch or Alpha tapioca starch is made from tapioca starch and is widely used in industry and food: 1, Used for briquetting (BBQ Charcoal, Shisha Charcoal, Carbon charcoal...) and steel casting or metal casting (mix 2% Kaolin) 2. Used for glue . 3. Used for fertilizer briquetting, release sustaining 4. Used in feed - as a binder of aquatic feed 5. Used in building materials - as an interior wall coating adhesive. 6. Used in mineral processing - Inhibitor of flotation. 7. Used as a binder of mosquito-repellent and Buddhist incense.
