Johnson Screens SuperFlo - Screens
From Johnson Screens
Downhole sand control screen must retain formation sand and allow easy passage of production fluids and drill-in solids. These critical functions can now be performed with unequaled efficiency by Superflo – the highest permeability screen currently available on the market.
Slip-On screen which utilizes a finer wire, thus increasing the screen open area with a narrow slot size distribution. This construction improves resistance to erosion hazards while reducing fluid velocity through the screen and also improves the sand retention properties of the screen. Large open area and lower entrance velocities allow a stable filter cake to form. Capable of handling finer, less uniform sands.
Cost effective alternative to premium screens in uniform sands. Direct retention for sand with CU < 5 Protective covers (shroud) to protect screen surface against run-in damage Very fine wire for a very high open area jacket and an increased Slot control. Additional support ribs maximize roundness of the jacket thus providing excellent slot control for better sand retention and prevention of filter cake build-up. Shrink-fitted recessed end-ring components are carefully engineered to give greater jacket protection during final Installation.
Recommended for: Completion of long horizontal wells in well sorted, homogeneous reservoirs with medium to short radius wells. Completion of long horizontal wells in well sorted, homogeneous reservoirs with medium to short radius wells.
