Abstract[English]
A method includes, in response to an indication that a length of tubing has become stuck at a downhole location in a wellbore drilled into a subterranean zone, at least partially displacing wellbore fluid with a displacement fluid having a specific gravity greater than a specific gravity of the wellbore fluid. The method further includes, after the at least partially displacing the wellbore fluid with the displacement fluid, dislodging the length of tubing from the downhole location.[French]
Un procédé comprend, en réponse à une indication selon laquelle une longueur de tube s'est coincée à un emplacement de fond de trou dans un puits de forage foré dans une zone souterraine, le déplacement au moins partiel d'un fluide de puits de forage avec un fluide de déplacement ayant une gravité spécifique supérieure à une gravité spécifique du fluide de puits de forage. Le procédé comprend en outre, après le déplacement au moins partiel du fluide de puits de forage avec le fluide de déplacement, le délogement de la longueur de tube depuis l'emplacement de fond de trou.
