Understanding the Slotted Liner Completion

A slotted liner completion involves running a wellbore tubular into the well that has slots or holes made before the string is assembled and run into the wellboreA slotted liner completion is preferred, because itresults in better solid control and lesser flow convergence. However, the compounded effect of formation  Unlike a perforated liner, which is typically completed after being run into the wellbore, a slotted liner is pre-fabricated with precise slots20231113—Prepare to Run Lower Completion. Commence Running Lower Completion.RIH 4-1/2” Slotted Liner Lower Completion Joints. Make-up 4-1/2” Swellable Packer. This method is often considered similar to an open hole completion in its function, allowing reservoir fluids to enter the wellbore through these designated openingsThis paper introduces an analytical skin model for theslotted liner, which incorporates these phenomena, and can be used to optimize theslotted linerdesign. As noted in industry literature, such as the work by Wang and colleagues, slotted liners and perforated completions are common for horizontal wells, serving as a conduit for fluid flow20231113—Prepare to Run Lower Completion.
