Biopolymers such as xanthan are being used increasingly in oilfield operations where the stability of the biopolymer is a prime consideration. The stability of xanthan depends on the brine salinity. Good viscosity retention over many months is observed in sea water at 90/sup 0/C. The successful application of xanthan at temperatures higher than 90/sup 0/C requires an understanding of the factors that limit stability. These factors include the nature of the polymer and the mechanisms of degradation. The stability features of a novel biopolymer are also described.
