Nourisi® Drilling Grade Welan Gum is a premium bio-polymer specifically engineered for demanding oil and gas drilling, completion, and stimulation operations. Serves as a multifunctional rheology modifier and fluid loss control agent, delivering exceptional performance under extreme downhole conditions to enhance operational efficiency and wellbore stability.
Superior low-end rheology provides outstanding suspension and hole-cleaning capabilities, effectively transporting drill cuttings and preventing barite sag even in high-angle and extended-reach wells
Exceptional thermal stability maintains consistent viscosity and fluid properties in high-temperature, high-pressure (HTHP) reservoirs
Excellent salt tolerance ensures reliable performance in seawater, brine, and high-salinity formation fluid environments
Effective fluid loss control forms a thin, low-permeability filter cake to minimize formation damage and protect reservoir permeability
Rigorous quality control for consistent supply.

Functions as a high-performance viscosifier and fluid-loss control agent in water-based drilling mud systems, providing exceptional cuttings suspension and hole-cleaning efficiency even in deviated and horizontal wells while maintaining stable rheology under high-pressure and high-temperature (HPHT) conditions up to 150°C (300°F).
Serves as a rheology modifier in high-density brine systems (including NaCl, KCl, CaCl₂, and CaBr₂) for completion, packer, and workover operations, delivering reliable viscosity for fluid loss control and solids suspension without causing formation damage.
Incorporated into oil well cement slurries to control fluid loss, enhance slurry stability, and prevent free water separation, ensuring consistent cement placement and zonal isolation in critical casing and liner cementing jobs.
Utilized as a mobility control agent in polymer flooding applications, offering superior thickening efficiency and resistance to mechanical degradation, salinity, and high temperature for improved sweep efficiency and oil displacement.
Nourisi® Drilling Grade Welan Gum demonstrates outstanding functional properties specifically engineered for demanding oilfield applications:
Superior low-end rheology providing exceptional cuttings suspension and barite sag prevention in high-angle and extended-reach wells, even at minimal dosage concentrations (0.1–0.3%);
Exceptional thermal stability maintaining consistent viscosity and fluid loss control performance under extreme downhole conditions up to 150°C (300°F) for extended operational periods;
Excellent salt tolerance ensuring reliable rheological performance in seawater, saturated brine, and high-salinity formation fluid environments (up to 200,000 ppm TDS);
Effective fluid loss control forming thin, low-permeability filter cakes that minimize formation damage and protect sensitive reservoir permeability;
Nourisi®Drilling Grade Welan Gum is recognized as a safe industrial additive and complies with the quality and safety specifications established by relevant international standards, including ISO 9001 for quality management systems and industrial-grade chemical regulations. The product meets all required standards for microbial control and heavy metal limits. However, we recommend that users verify this product's compliance with specific local regulations and safety requirements in their target markets, particularly in industries with strict environmental regulations or specific waste disposal requirements.
25kg kraft bag lined with a polyethylene bag, meanwhile, other packaging are available on request. Store away from heat and moisture.
