Premium Screens

Premium Screens are designed for openhole completions with or without a gravel pack.

Development and testing of these screens is geared towards robustness, reliability, sand control efficiency and long life in harsh production conditions.

Premium screens are available in various pore sizes and metallurgies, which make them adaptable to the specific needs of each application.

Composed of:

  • A base pipe perforated to 10% flow area to capitalize on the high flow area of the filter-mesh material.
  • An inner drainage layer to ensure uniform standoff between the filtration medium and the basepipe.
  • A sintered laminate filter cartridge for sand retention.
  • A protective shroud.

Uses

  • Openhole gravel packs.
  • Openhole stand-alone screen completions.
  • Other sand control applications where a superflow sand retention method is desired.

Benefits

  • Designed for several service conditions.
  • Safe and reliable.
  • Long life in harsh production conditions.
  • Easy and quick installation.
