fluid loss agnet for oil drilling

1. Drillstarch
Drillstarch is a non-fermenting starch used to control filtration in water based muds.
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 6-17 kg/m3 §C 6 ppb). A concentration of 11-20 kg/m3 (4-7 ppb) will provide good base properties when used as a primary colloid in low solids muds. Biocide treatment is recommended along with drillstarch application.
c. Typical Physical & Chemical Properties:
Appearance.......................................................................White powder
Hygroscopic............................................................................Moderate
PH in water...............................................................................Neutral
Bulk Density............................................................640 kg/m3 (40 lbs/ft3)
Temperature Stability.................................................Approx 100ÿãC (212 ÿãF)
Ion Stability...............................................................Not sensitive to ions
Toxicity.................................................................................Non-Toxic
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. Drillstarch is non-toxic and is considered to be harmless in the marine ecosystem. Drillstarch does not have a restricted classification for transportation by international or domestic regulatory agencies.
