5. SPEC 13A Sec. 16 Drilling-grade Starch Current Specifications
16.1 Principle
Drilling grade starch can be manufactured from several kinds of native starches. The starch should be made cold water hydratable (pregelatinized) and may be treated further in such a way that it is suitable for use as a filtrate reducing agent in water-base drilling fluids.
Drilling grade starch should be free-flowing and free from lumps. Drilling grade starch shall be deemed to meet this International Standard if a composite sample representing no more than one day's production conforms to the physical specifications of Table 15, represents the product produced, and is controlled by the manufacturer.
