This paper reports on the development of a process for recycling polysaccharide-viscosified brine completion fluids. The process used oxidants generated directly in the used brine by electrolysis to break the viscosity. The treated brines can be filtered with conventional equipment, reviscosified, and reused. The process has been applied on a laboratory scale to Br{sup {minus}}/Cl{sup {minus}} brines containing Na{sup +}, K{sup +}, Ca{sup +2}, and Zn{sup +2} cations. Calculations with information from pilot-scale tests on NaBr/NaCl brines indicate that the process should be attractive economically.
