AMW - Model ASW -Mill Slotted Liners
The ASW Slotted Liner (sometimes called a standalone screen or scab liner) is a robust and cost-effective solution that provides borehole stability and effective sand control in long horizontal completions and low productivity wells. It is also used in Steam Assisted Gravity Drainage (SAGD) applications for effective downhole steam distribution. Slotted liners are manufactured with CNC controlled slotting machines, which can produce a full spectrum of slot designs. Slot widths range from 0.010 in. to 0.250 in. Base pipe diameters range from 1.5 in. up to 18.0 in. Pipe lengths of any size can be slotted.
The slot size and slotting pattern are customized to achieve the required open area based on customer specifications. Multiple-staggered, non-overlapping patterns optimize tensile and torsion strength and increase the open area by two times compared to
single cut patterns.
All slotted joints are de-burred, cleaned and drift tested according to API standards. Every slot is visually inspected and cleaned. All threads and couplings are thoroughly cleaned and lubricated. The size, grade and weight of the base-pipe are per API casing or tubing specification as required based on customers instructions.
