Abstract:
A method for carrying out a well treatment in a well (e. g. fracturing, sand control, etc. ) wherein a high-viscosity treatment fluid containing a gel (e. g. a polymeric gelling agent) is flowed down the well along with a bacteria selected from the generic classes of Enterococcus and Corynebacterium or a mixture of the two, which is capable of digesting and/or cleaving the gel to reduce the viscosity of the gel at the conclusion of the well treatment.
