Well completion is the process of making a well ready for production (or injection) after drilling operations. This principally involves preparing the bottom of the hole to the required specifications, running in the production tubing and its associated down hole tools as well as perforating and stimulating as required. Sometimes, the process of running in and cementing the casing is also included. After a well has been drilled, should the drilling fluids be removed, the well would eventually close in upon itself. Casing ensures that this will not happen while also protecting the wellstream from outside incumbents, like water or sand.

- Completação, na produção de petróleo, é o processo de deixar um poço pronto para a produção (ou injeção de água, diversos fluidos de tratamento e estimulação do reservatório ou gases). Isso envolve, principalmente, a preparação do fluido da perfuração para as especificações exigidas, a execução do tubo de produção e suas ferramentas associadas baixadas na perfuração, bem como perfuração e estimulação, conforme necessário. Às vezes, o processo de execução e cimentar o revestimento também está incluído. (pt)
- 完井是指人們在钻井作业完成后，讓油井做好生产准备的过程。这一過程主要包括安装和相关的井下工具，以及根据需要进行穿孔。有时还包括套管的穿入和固井过程。在钻井之后，如果钻井液被清除，油井最终会自我封闭。套管可以确保这种情况不会发生，同时还可以保护井流不受外部侵入物（如水或沙）的影响。 (zh)
- Dans les domaines de la production de pétrole et de gaz naturel, gaz de houille ou gaz de schiste, et pour les forages d'eau, la complétion d'un puits de forage est l'ensemble des opérations de finition du puits, qui doivent permettre sa mise en service optimale, que ce soit en production, en injection ou en observation. Le « compléteur » en est responsable et y travaille avec le foreur qui cherchent à répondre aux spécifications techniques requises pour le meilleur rendement et un bon fonctionnement lors de toute la phase d'extraction des hydrocarbures ou d'exploitation de l'eau.

- Dans les domaines de la production de pétrole et de gaz naturel, gaz de houille ou gaz de schiste, et pour les forages d'eau, la complétion d'un puits de forage est l'ensemble des opérations de finition du puits, qui doivent permettre sa mise en service optimale, que ce soit en production, en injection ou en observation. Le « compléteur » en est responsable et y travaille avec le foreur qui cherchent à répondre aux spécifications techniques requises pour le meilleur rendement et un bon fonctionnement lors de toute la phase d'extraction des hydrocarbures ou d'exploitation de l'eau. La qualité de la complétion augmentera aussi la durée du vie du puits.L'essentiel du travail du « compléteur » est la préparation du fond du forage ou des forages multiples (dans le cas d'un seul puits conduisant à plusieurs forages horizontaux par exemple, ce qui est de plus en plus fréquent, en Amérique du Nord notamment depuis la fin des années 1990).Parfois, le processus de démarrage (rodage) et de cimentation du tubage (« ») est également inclus. La qualité de la complétion est souvent vérifiée par la réalisation de plusieurs diagraphies. (fr)
