Horizontal well completion

the completion that can be run through a given radius of curvature will depend on 1.the radial clearance between the completion item and hole(liner size), 2. the length and flexibility of the completion, 3.the rating of the connection   Horizontal well Completion Options   1.Open hole 25% 2.Slotted Liner 55% 3.Liner with...
