A retrievable frac mandrel and a well control adapter are used to efficiently accomplish well completion, re-completion or workover. The retrievable frac mandrel is inserted in a tubing head spool of a well to be completed, re-completed or re-worked. The well control adapter is mounted to a top of the tubing head spool and seals off against a top of the retrievable frac mandrel. After well completion, re-completion or workover is completed, the frac mandrel can be retrieved from the tubing head spool without killing or plugging the well.
Un mandrin de fracturation récupérable et un adaptateur de contrôle de puits sont utilisés pour accomplir la complétion, la remise en production ou le reconditionnement efficaces de puits. Le mandrin de fracturation récupérable est inséré dans une bobine de la tête de colonne de production d'un puits à compléter, à remettre en production ou à reconditionner. L'adaptateur de contrôle de puits, qui est fixé sur le dessus de la bobine de la tête de colonne de production, ferme le dessus du mandrin de fracturation récupérable. Après la complétion, la remise en production ou le reconditionnement du puits, on peut retirer le mandrin de fracturation de la bobine de la tête de colonne de production, sans tuer ou boucher le puits.
