The pre-packed screen have a double layer of high performance
screen, having a very accurate V-shaped wire welded to support rods
and a slot opening for the outer screen, which is selected to
retain the formation sand, and an inner screen to retain the media
The pre-racked screens simplify the contractor's work, improve the
odds for successful development and offer long-term benefits for
For the contractor, the pre-packed screen eliminates the need for a
larger borehole. It shortens the amount of time required to drill a
well, and speeds development time.
It uses ceramic beads as the filter media. This unique concept
provides a filter pack that is less likely to get fouled with
biofilm and encrustation. It also uses calibrated sand, either with
or without epoxy resin, which is contained within the annulus of
two concentric screens.
Close control of slot tolerances, designed to prevent sand
It also lowers overall maintenance costs for the owner.

Oasis well screen offers a variety of packing medias to cover your
1. Available in oil and gas well completions, especially in an open
or cased hole with unconsolidated formations where
stand-alone screen is needed.
2.Pre-packed screen is easy to install for its unique construction.
3.Stainless steel material gives it ability of resisting erosion.
4.Pre-packed screen is equipped with packed layer itself. This
unique configuration eliminates gravel placement and significantly
shorten the time of drilling a well.
5. Stronger construction like support rods reduces maintenance
6. Pre-packed screen is quite affordable in contrast to slotted
