Coiled tubing screen and method of well completion

摘要

The present invention allows a well to be produced through a screen without the need for a gravel pack. This is accomplished by the placement of an expandable screen that can move radially outwardly when placed at the desired location against the wellbore and be porous enough with sufficient open area to allow production from the formation. The screen is placed in the desired location by using coiled tubing which can be preperforated for a support for the screen. The screen is protected during delivery to the desired location in the wellbore by providing a disposable or removable outer cover which can be disposed of after proper location on the screen in the wellbore.
