Summary: | 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.
L'invention concerne un procédé d'amélioration de l'efficacité du nettoyage de puits dans une formation souterraine. On obtient un traitement plus efficace en traitant d'abord le puits avec un fluide de nettoyage dégradant par une action enzymatique des améliorants de viscosité polymères, puis en retirant les solides contenus dans les fluides de forage. |
