API 5ct Caseing and Tubing
Il tubo di involucro viene spesso utilizzato nei progetti di costruzione sotterranei per racchiudere o proteggere le linee di utilità da danneggiare.
Una volta che un pozzo è stato perforato, se deve diventare un pozzo di produzione, il pozzo deve essere sottoposto a completamento. Durante la perforazione di un pozzo taglia le formazioni rocciose e consente agli ingegneri di perforazione di raggiungere il serbatoio sottostante, i lati grezzi del pozzo non possono supportarsi. Simile alle ossa della colonna vertebrale che proteggono il midollo spinale, l'involucro è un tubo che è impostato all'interno del pozzo praticato per proteggere e supportare il Wellstream.
