Curdlan is a high molecular polysaccharide produced by microbial fermentation of sugar. At a specific high temperature, it forms a stably irreversible gel, which is highly resistant to heat, acid, alkali, salinity, pressure, and shearing force. It acts as a high temperature-resistant profile control and water plugging agent.


Polyanionic Cellulose (PAC) and Carboxymethyl Cellulose (CMC) perform as a fluid loss control agent, viscosity agent, and shale inhibitor in water-based mud. 


Welan Gum acts as a critical spacer fluid component in oil well drilling. It is also used for purposes of hydraulic fracturing, wellbore cleanup, cementing, and drilling for viscosity enhancement and friction pressure reduction. In the secondary oil recovery process, Welan Gum acts as a polymeric thickening agent. 


Xanthan Gum, a high-molecular-weight biopolymer, provides versatile rheology control in a wide range of brines, drilling and fracturing fluids.
