Starch

Modified Starch is a high-quality non-ionic natural polymer developed for use in all types of water-based drilling fluids, completion fluids, and stimulation systems. The product functions primarily as a filtration control additive and rheology stabilizer, helping improve drilling fluid performance under various operational conditions.

Its advanced formulation enables excellent compatibility with fresh water, seawater, saturated saltwater, and high-hardness brines including KCl, NaCl, MgCl₂, and CaCl₂ systems. Modified Starch effectively reduces API fluid loss while improving wellbore stability and minimizing filtrate invasion into permeable formations.

Due to its non-damaging characteristics and broad operational tolerance, Modified Starch is widely used in modern drilling operations where stable rheology and reliable filtration control are essential.
