Continuous Slot-Pre-Pack

Continuous Slot-Pre-Pack

UBO Screen is a viable, proven and cost effective option to conventional gravel pack. Factory installed ceramic beads fill the annulus between the inner and outer screen barrels.

Advantages of UBO pre-pack screens are:

-- Uniform filter media

-- Consistent fill

-- Increased Tensile and Collapse

-- Special lengths

-- Custom applications

-- Faster well completion

-- Lower overall cost

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 pack.
The pre-racked screens simplify the contractor's work, improve the odds for successful development and offer long-term benefits for the owner.

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 migration.

It also lowers overall maintenance costs for the owner.

Ubo is specialized in producing and distributing wedge wire screen, lauter tun screens, sieve bend screen, sieve plate screen, water strainer&nozzle, screen nozzles, centrifuge screens and baskets, header-lateral.
