Equipment and methods which may be used in conjunction with an underbalanced well completion. In a described embodiment, a valve for use in a subterranean well in conjunction with a tool conveyed through the valve in a container is provided. The valve includes a passage formed longitudinally through the valve, a closure assembly which selectively permits and prevents flow through the passage, and an engagement device which engages the container as the tool is conveyed through the passage. The closure assembly permits flow through the passage when the container is conveyed into the passage, and the closure assembly prevents flow through the passage when the container is removed from the passage. Engagement between the container and the engagement device separates the tool from the container.

Il s'agit d'un équipement et de méthodes utilisables concurremment avec une complétion de puits sous-équilibrée. Dans une version décrite précédemment, un clapet est fourni pour être utilisé dans un puits souterrain, concurremment avec un outil acheminé à travers le clapet, dans un contenant. Ce clapet comprend un passage formé longitudinalement à travers le clapet, un dispositif de fermeture qui, de manière sélective, permet ou empêche l'écoulement à travers le passage, et un dispositif d'engagement qui accouple le contenant, lorsque l'outil est acheminé à travers le passage. Le dispositif de fermeture permet l'écoulement à travers le passage, lorsque le contenant est acheminé dans le passage, et le dispositif de fermeture empêche l'écoulement à travers le passage, lorsque le contenant est enlevé du passage. L'accouplement entre le contenant et le dispositif d'engagement sépare l'outil du contenant.
