Product Description

Drill starch is a non-fermenting starch used to control filtration in water based mud.

A. Application:
Drillstarch primarily provides filtration control in all water base drilling fluids.

B. Recommended Treatment:
The average treatment level with drillstarch for filtration control is 6 to 17 kg/m3 to 6 ppb). A concentration of 11 to 20 kg/m3 (4 to 7 ppb) will provide good base properties when used as a primary colloid in low solids muds. Biocide treatment is recommended along with drillstarch application.

D. Environmental, Safety Handling and Shipping Reference:
Utilize normal precautions for employee protection when handling chemical products.

Use of appropriate respirator, gloves, goggles and apron is recommended for employee comfort and protection. Drill starch is non-toxic and is considered to be harmless in the marine ecosystem. Drill starch does not have a restricted classification for transportation by international or domestic regulatory agencies.
