Slotted liners can be selected as a substitute for pre-holed liner, typically as a personal choice or from established practice on a field. It may also be selected to offer a low cost control of sand/solids production. The slotted liner is machined with multiple longitudinal slots, for instance 2 mm x 50mm, spread throughout the size and circumference of each joint. Recent advances in laser slicing implies that slotting can now be accomplished less expensive to much smaller slot widths and in some state of affairs slotted liner is now used for the same functionality as sand management screens.
Careful planning is required so that the correct casing for each properly is put in. Subsurface characteristics, the diameter of the properly, and the pressures and temperatures skilled all through the well, are all taken into account when planning the various casing strings. A subassembly device that is bolted to the top of the BOP stack that's designed to remove traditional bolt-flanges to connect lubricator heads and utilize tapered-wedge and lock ring designs.
