Abstract
On a découvert que l'adhésion provoquée par les agents de soutènement utilisés dans une opération de remblayage de fracturation ou de gravillonnage des crépines lors des efforts de récupération d'hydrocarbures peut être limitée par le placement d'un fluide de décollement d'agents de soutènement dans un espace de fond, tel qu'un annulaire adjacent à un système d'outillage ou outillage de service. Un opération est exécutée qui comporte la circulation d'un fluide de transport comprenant un agent de soutènement à travers le système d'outillage. Le fluide de transport est gélifié et éventuellement réticulé. Le fluide de décollement d'agents de soutènement est entraîné à travers le système d'outillage pour rompre le gel, entrer en contact avec l'agent de soutènement et dégager sensiblement l'agent de soutènement du système d'outillage. Enfin, le système d'outillage est extrait du fond. Le fluide de décollement d'agent de soutènement comporte un diluant, tel qu'un fluide aqueux, une saumure, ou un fluide non aqueux, et une quantité efficace de composant de rupture de gel et peut, mais pas obligatoirement, contenir un composé de réduction de tension superficielle, tel qu'un tensioactif.
