1. In the food industry, Welan gum can be used in bakery products, dairy products, fruit juice, milk beverages, sugar, icing sugar, jam, meat and all kinds of desserts processing.

2. In the oil industry, Welan gum can be used for deployment of drilling mud in order to maintain the viscosity of water-based drilling fluid and control its rheological properties. Welan gum is also a new type of oil displacement agent used for tertiary oil recovery wells.Deploying aqueous solutions of welan gum with the right concentration injection into the wells, and putting the pressure into the oil reservoir, it can greatly improve the oil recovery rate. In addition, Welan gum can also be used in flow improver of completion, workover, stratum fracture, and heavy oil transportation.

3. Welan gum can also be widely used in cement and concrete, and enhance the water retention of mud, and it does not need to use dispersants like other additives when used as the water retention agent. Welan gum can increase the plasticity, suspension amount, air content, and ability of anti-subsidence and flow characteristics and anti-dehydration of cement. These characteristics of improvements remain unchanged when the temperature increases. Compared with other additives, Welan gum with the lower concentration can achieve a very good effect.
