Celotech’s modified starch ether, derived from pregelatinized starch, is engineered for oil drilling applications to meet the demanding requirements of modern drilling fluids. This product effectively functions as a filtrate reducer, viscosifier, and fluid loss control agent. In water-based drilling mud systems, it enhances rheological stability, reduces API fluid loss, and improves the lubricity of the mud. Its rapid hydration and compatibility with other additives make it ideal for both fresh and saltwater systems. Celotech’s starch ether ensures consistent performance under high temperature and pressure conditions, helping to maintain wellbore stability and drilling efficiency.
Prestar® 1201 is a high-performance pregelatinized starch specifically developed for use in oilfield drilling fluids. It offers excellent fluid loss control, salt tolerance, and thermal stability, making it an ideal additive for water-based drilling systems under a wide range of field conditions.
Water-based drilling fluids (freshwater, seawater, and brine systems)
Fluid loss control in oil and gas drilling
Completion and workover fluids
Lost circulation materials (as a blend component)
With its reliable performance, salt resistance, and ease of use, Prestar® 1201 is a trusted solution for improving the performance and efficiency of water-based drilling fluids in complex and demanding oilfield operations.
