Apparatus for recompleting an oil and/or gas well includes a primary tubing hanger, and primary well tubing hung from the hanger within the well, and a communication/hanger nipple, located below the primary tubing hanger, which is suitable for receiving and locating a coil tubing hanger. The communication/hanger nipple is run into the well as part of the initial completion in any situation where there is a potential requirement for a coil tubing completion later in the life of the well but plays no part in the normal primary production operation of the well. However, should production fail for any reason, requiring coil tubing recompletion, the communication/hanger nipple is available to support the coil tubing and provide communication to the subsurface equipment without the necessity of modifying the primary tubing hanger.
Dispositif de remise en production d'un puits de pétrole ou de gaz comprenant un dispositif de suspension des tubes de production primaire et des tubes de production primaires accrochés au dispositif de suspension dans le puits, et un mamelon de dispositif de suspension/de raccordement, placé sous le dispositif de suspension des tubes de production primaire, qui peut recevoir et retenir un dispositif de suspension de tube de production concentrique. Le mamelon est descendu dans le puits pendant la complétion initiale dans tous les cas où il est possible que la complétion avec tube de production concentrique devienne nécessaire plus tard au cours de la durée de vie du puits, mais il ne joue aucun rôle pendant la production primaire normale du puits. Toutefois, s'il y avait une baisse importante de la production pour une raison quelconque, qui nécessiterait la remise en production au moyen d'un tube de production concentrique, le mamelon de raccordement/de dispositif de suspension serait là pour retenir le tube de production concentrique et permettre la communication avec l'équipement souterrain sans avoir à modifier le dispositif de suspension des tubes de production primaire.
