The slotted liner completion is similar to an open hole completion and has all the major advantages and disadvantages discussed for open hole completions. The only difference is that a slotted liner is hung in the open hole interval to minimize [[/Drilling_problems#Hole_instability|sloughing]] of the formation into the well bore ([[:Image:Charles-l-vavra-john-g-kaldi-robert-m-sneider_capillary-pressure_1.jpg|Figure 1b]]). A screen and liner completion is similar to the slotted liner completion in that a screen and liner is set in the open hole section of the wellbore. The difference is that gravel is sometimes placed behind the screen ([[:File:Well-completions_fig2.png|Figure 2a]]). The advantages and disadvantages are the same as for open hole completions. The screen and liner completion is used primarily in [[unconsolidated]] formations to prevent the movement of formation materials into the wellbore, restricting the flow of reservoir fluids. | The slotted liner completion is similar to an open hole completion and has all the major advantages and disadvantages discussed for open hole completions.
