Abstract
Une isolation de tête de puits s'emboitant dans le boitier et une méthode d'utilisation d'un outil protègent les têtes de puits des pressions ascendantes induites par les pressions de fluide élevées et les débits élevés utilisés pour stimuler les puits à basse pression. Un ensemble de garniture d'étanchéité amovible monté à une extrémité inférieure d'un mandrin de l'outil permet de saisir le boitier et de transférer les pressions ascendantes directement au boitier. La sécurité du processus est ainsi considérablement améliorée.
