摘要
A process for the degradation with acid of a viscous microbial polysaccharide formulation which is applied in oil and/or gas reservoir operations, wherein the polysaccharide formulation contains an amount of a salt or a salt mixture which is sufficient to adjust the transition temperature of the polysaccharide such that it is close to the reservoir operating temperature. A process for the preparation of an acid degradable polysaccharide formulation and a polysaccharide formulation.
