Abstract:
A method of drilling and completing a well can include drilling a section of a wellbore, positioning a perforated shroud in the section of the wellbore, securing the perforated shroud by setting a hanger, and isolating the section of the wellbore from a remainder of the wellbore vertically above the section of the wellbore. The drilling, positioning, securing and isolating steps can be performed while the section of the wellbore is not exposed to a liquid column extending to a surface location. The drilling, positioning, securing and isolating steps can be performed in a single trip of a drill string into the wellbore.
