Superior Sand Control with Precision-Seamed Keystone Slots
G&L Slotco Seamed keystone liners provide the sand control solution for many horizontal well completions. Primarily used in SAGD and thermal applications, the slot profile is anti plugging where the outside diameter width is smaller than the inside diameter width. The OD width provides the required sand control and is usually designed to retain and bridge the larger D10 to D15 formation sand grain sizes. Any grains that do pass through the OD aperture are free to be produced through the larger ID slot width.
The liner is first straight cut slotted to the desired Inside Diameter width, commonly at least 30% larger than the OD width. The liner is then cleaned and deburred before the seaming process.
Precision Longitudinal Seaming System - Manufacturing In Our Canadian Operation
  • Through partnership with the original inventors of seaming technology, G&L Slotco utilizes the most advanced design in seaming technology
  • CNC closed loop optic eye measuring system which measures slot widths “on the fly” while adjusting hydraulic yielding pressures on roller heads during correction passes to ensure finished product meets specification
  • Seaming head accumulators allowing seaming heads to adjust to diverse pipe hardness and ovality
  • Able to produce computer generated quality control reports on a per slot, per joint basis both individual joint bar graphs and non conformance summary reports in PDF file on CD
  • CNC-controlled auto correction system. Ability to perform correction seaming passes at lower pressures to ensure 100% slots in specification
  • Ability to yield both peripheral edges of slots with equal pressure resulting in superior quality uniform slot widths on every slot.
  • Depth of penetration of slot profile OD to ID is between 0.040" - 0.050”
  • Patented System and Process
  • Total seaming capacity of 28,000 meters/month
