Starch API Grade Supplier and Manufacturer

Starch API Grade

Description
Starch is a high-quality polysaccharide used to provide filtration control in all types of water-base drilling fluids. This non-ionic natural polymer is effective in all make-up waters, including high-salinity and high-hardness brines.

Applications

STARCH is an economical and effective filtration-control additive. It works in all waters, including fresh water, brackish water, seawater, and saturated salt water. It may be used in most mud systems, including lime, gyp, lignosulfonate, polymer, non-dispersed, potassium and others. Normal treatments range from 4 to 8 lb/bbl (11.4 to 22.8 kg/m3), depending on the make-up-water chemistry and desired fluid loss. A minimum concentration of STARCH is required before a significant reduction in fluid loss will be observed. Unless the system has a base of saturated salt water or has a very high pH, a biocide will be necessary to prevent bacterial degradation.
