The goal of the study is to find the optimal design of slotted liners by 3D finite element analysis and experimental study. Slotted liners are widely used in horizontal wells because of the abilities to ensure wellbore integrity and sand control. During installation and operations, the slotted liners have to be strong enough to hold axial loads and radial compression to prevent excessive buckling and deformation of slots. Experiments were designed to select the grades of materials, diameter/thickness of pipes, slot pattern. Finite element models were developed to decide the slotted liner design under various load conditions. The study showed considerations for slotted liner design and analyzed how much material grades, casing/tubing dimension and slot patterns can be expected to evaluate the risk of slotted liner failure.
