Diutan gum used in tertiary oil recovery

Diutan gum used in tertiary oil recovery
Description:
Diutan gum was developed specifically for use with cementitious materials and the newest class of superplasticizers. It enables formulators and designers to improve the performance of hardened materials by controlling flow, segregation, sedimentation and bleed. In addition, diutan develops a higher degree of pseudoplasticity, greater low shear rate viscosity (LSRV), and improved viscosity retention at elevated temperatures when compared to traditional polymeric rheology modifiers used in drilling, workover or completion fluids.
Application:
Diutan gum biopolyer is a high efficiency, pseudoplastic viscosifier and suspension agent used in water based drilling, workover and completion fluids. Welan gum is also used in construction applications and other general industrial uses.
Tertiary oil recovery

Diutan gum belongs to a class of rheology modifying agents possessing pseudoplastic behavior. Pseudoplastic materials are characterized by viscosity which increases and decreases virtually instantaneously in response to the removal and application of shear. This property results in fluids which readily flow but are capable of suspending or stabilizing components.
Packing:
Diutan gum is packed in 20 kg paper sack, 25 or 40 sacks per pallet.
Customized packaging is available.
