Abstract

L'invention concerne un procédé qui comprend les étapes consistant à déployer dans un puits un corps sensiblement longitudinal comprenant au moins en partie un matériau dégradable capable de libérer une substance chimique; positionner le corps longitudinal au niveau d'un site de fond du puits; et laisser le matériau dégradable se dégrader et la substance chimique se libérer.
