Bridge slot screens have openings arranged in rows and are staggered to reduce the negative effect on the screen's strength. Typically the slots are punched in a flat sheet that is subsequently rolled into a tube and welded.
Advantages offered by this type of screen are:
High strength through resistance to twisting, compressive, and tensile forces
A smooth bore that does not impede the passage of probes, tools, etc.
Applications
Formations with large particle sizes
Large diameter wells
Low to medium flow rates
