Pre-packed screen used as stand-alone screen Pre-packed screen provide excellence service of

sand control in oil, gas and water wells for its unique construction. Pre-packed screen is a

modification of pipe-based wire wrapped screen. Its addition of a modular gravel pack makes

it especially suitable for sand control where conventional gravel packing fails.

Pre-packed screens are ideal for horizontal boreholes and boreholes that deviate from vertical.

the pre-packed screen is well suited for situations where placing a conventional gravel pack is difficult.

the screen assembilies save time and reduce logistical planning, because no handling

and no installation of bulk pack material is needed.
