ST SERIES OF HYDROXYETHYL CELLULOSE (HEC)
PRODUCT DESCRIPTION
ST series of HEC is made from natural polymer cellulose, is non-ionic water-soluble polymer, it is white to slightly yellow, odorless and tasteless powdered solid. It is non-ionic water-soluble polymer, effective in thickening, bonding, emulsifying, dispersing, stabilizing and water preserving, forming film and providing protective colloid effect. It is very easily soluble not only in cold water, but also in hot water, and can provide solutions with wider range of viscosity.

FEATURES
1. ST series of HEC is mainly used as viscosifier and water loss controller in oil drilling industry.
2. High-viscosity HEC is mainly used as viscosifier in well-completing or finishing fluid.
3. Low-viscosity HEC is mainly used as water loss controller.
4. HEC used as thickener will impart good mobility and stability to various slurries necessary for drilling, completion, cementing and fracturing operations.
5. In drilling, HEC can increase the sand carrying capability of the slurry and extend the service life of drill bits.
6. In low-solid content completion fluid and cementing fluid, the excellent water loss control performance of HEC can prevent large amount of water in the slurry from entering into the oil reservoir and enhancing the stabilizing capability of the wall of the reservoir.
