Abstract
A method is provided for improving the effectiveness of cleaning up wells in a subterranean formation. The treatment is made more effective by first treating the well with a clean-up fluid that enzymatically degrades residual polymeric viscosifiers followed by removing solids contained in drill-in fluids.
