efficient sand control

Using movement CNC precise control and the newest German cutters the perfect accuracy of cutting and outstanding quality of manufactured production are achieved.

Our slotted liners help to perform effective and cost-efficient sand retain control for wells with heavy crude or viscous oil.

Multi-spindle and multi-position machines for slots cutting allow choosing any combination of slots cutting which therefore provides necessary open flow area or flow profile (or pumping) at the well horizon.

The slot size range of 250 - 1000 mkm is defined according to the core grain-size analysis sample provided by the Customer.
