Well Сompletions Solutions

Perforated/slotted liners/screens

High filtering capacity
High-quality corrosion resistant materials for extended well life
Minimum hydraulic resistance and pressure losses
Uniform fluid flow inside the liner
Optimally selected height of the wrap layer provides for stable screen operation in a wide range of downhole conditions
Filtering elements/parts have a large number of support points, which increases their axial and radial strength and capacity to withstand high loads
The monolith structure of a direct-wrap wire screen, formed in a direct welding process provides for its higher rotational load capacity
General Description

Wells with very fine-grained (75-125 microns / 0,003-0,005 in) and finegrained (125-250 microns / 0,005-0,01 in) sand; highly homogeneous, homogeneous and heterogeneous sand fractions.
