2. Wide Selection of Well Screens
Well screens hold back sand from the gravel pack or formation, thus keeping a constant passage for production fluids.
Owing to our large selection of well screens and expertise in sand control, we can help you choose the ideal screen that maximizes sand retention while minimizing flow impairment.
Better priced than suppliers like Weatherford or Schlumberger, Sovonex sand screens not only keep sand production under control but also considerably lower your expenses.
We offer a wide selection of different sand control screens that cover most sand production problems.
Due to their unique design, wire-wrapped screens have a 20 times higher flow area compared to slotted liners. Keystone-shaped stainless steel wire is wrapped around and welded to strong vertical wire ribs, forming a layer of precisely spaced openings that keep out fines without clogging the filter layer.
The advantages of this design at a glance:
· Keystone shaped wire reduces risk of screen plugging/clogging
· Self-cleaning
· Greatly reduced flow friction
Wire welded on every rib: High collapse resistance and precisely controlled screen gauge
