Gravel pre-packed wedge wire screen for sand control

Gravel pre-packed wedge wire screen for sand control combines stainless steel or carbon steel casing with continuous slot well screens for additional strength in deep well applications.The pipe body strength allows smaller wrap wires to be used, allowing for greater open area.

Features of Gravel pre-packed wedge wire screen for sand control :
Higher Collapse resistance.
Higher Load Strength.
Easily controlled open area for regulated flow rates.
Threaded Fittings in any specifications required.
Base pipes can be manufactured using stainless steel grades series or API 5CT carbon steel casing.
The pipe based well screens are recommended when high collapse resistance is required and when the screens’ length generates a high longitudinal constraint. The pipe strength allows smaller wrap wires to be used, yielding greater open area.
OASIS oil tools use prime pipe, thoroughly cleaned and de-burred after perforating.
