Polyanionic cellulose is an effective fluid loss reducer for water-based drilling muds. Due to the patented reagent grinding and packing technology, the reagent efficiency is superior to its current analogues. The reagent dissolves easily in cold water and provides effective reduction of fluid loss. It is supplied in granular form.
Range of applications
The reagent is used to reduce fluid loss of fresh, saline, potassium chloride and salt-saturated drilling muds. It facilitates the development of thin, dense, elastic and tight filter cake, reducing the area of filtrate invasion into the formation, preventing the intrusion of drilling mud solids, reduces the risk of differential pressure sticking.
