XANTHAN AS A UNIVERSAL POLYMER FOR OIL AND GAS PRODUCTION AND A PRODUCT OF BIOTECHNOLOGY

The interest in the use of xanthan biopolymer in oil and gas production processes has never lost its relevance. This fact is due to the high rheological properties of its aqueous solutions, as well as stability in the field conditions. Lately the issues of water-soluble polymers application are being reconsidered, as the issues of logistics and import substitution have become of great importance. This paper examines the main trends in the use of xanthan over the past decade, as well as the basics of its production.
