Slotted liner is a robust and effective device for sand control in the horizontal completion wells of SAGD and other thermal heavy oil recovery. Its excellent properties in withstanding installation loads and operation loads make it the premier choice for SAGD.
Slotted liners are manufactured by laser cutting process without contact operation. This process can effectively avoid undesirable factors which will cause the deformation of the base pipe. Laser cutting process uses windows interface for easy operation and accurate calculation.
Slotted liner geometry consists of slot length, slot width, slot density and slot distribution. All these parameters can be bespoken to achieve the required open area. For example, multiple staggered pattern or gang pattern significantly increases the open area compared with single cut pattern.
