SNF has been developing a wide range of polymers for EOR over more than 15 years. These products have been developed to accommodate the variety of conditions encountered in oil fields throughout the world.


Most Common EOR Polymers
FLOPAAM S (powder) and E (emulsion) series:

• FLOPAAM™ 3630
• FLOPAAM™ 3530
• FLOPAAM™ 3430
• FLOPAAM™ 3330 -*FLOPAAM™ 2530
• FLOPAAM™ 2430
• FLOPAAM™ 2330

SNF also produces specific polymers for difficult reservoirs.


SNF “standard” EOR polyacrylamide has better thermal stability than in the past (up to 90°C) due to the addition of stabilizing agents during the manufacturing process. For higher temperatures, (up to 120°C) sulfonated copolymers of acrylamide and sodium salt of acrylamide propyl sulfonated acid are produced. In addition to thermal stability, they present better stability to divalent ions, such as Ca ²+ and Mg²+, present in most hard brines or sea water. Although the molecular weights of these polymers are not as high as the standard FLOPAAM™ series, they can reach 12 million. They also have lower adsorption than standard hydrolyzed polyacrylamides.


SNF has developed a wide ranging series of sulfonated copolymer which are listed below:

• FLOPAAM™ AN 105
• FLOPAAM™ AN 113
• FLOPAAM™ AN 125 VLM
• FLOPAAM™ AN 125
• FLOPAAM™ DP/PT 2101B
• FLOPAAM™ AN 132

Liquid Xanthan Gum FLOCON 4800™

Xanthan Gum is well known to have excellent performance in high salinity brine. SNF obtained all the manufacturing and use patents of Pfizer FLOCON 4800™ Xanthan Gum, which is recognized by experts around the world as the highest grade Xanthan available for EOR projects.


Xanthan Gum is a polysaccharide biopolymer. It is produced by the microbial action of xanthomonas campestris on a substrate of carbohydrate media, with a protein supplement and an inorganic source of nitrogen. The biopolymer is an extracellular slime which forms on the surface of the cells. The fermented both is pasteurized to kill microbes and precipitated from the broth by alcohol, then concentrated.

• FLOCON 4800C™

SNF manufactures a wide array of mobility control polymers to accommodate the variety of conditions encountered in oil fields throughout the world. The diagram represents the viscosity and temperature range covered by the SNF hydrolyzed polyacrylamide and the sulphonated copolymer.


Research & Development laboratories at SNF are working to extend these ranges with new products and constant improvements to the existing ones.
