In a gravel-packed well, the size of the screen slot is selected to retain 90% or more of the gravel pack material. For the sand sieve analysis in Figure 3, the proper size screen in a gravel-packed well would have a slot opening of 0.015 inch to retain 90% of the material in the water-bearing strata. Chapter 7: Well Performance and Casing Selection for ... Well screen selection is nearly always a compromise, balancing the desire to optimize flow rate with the need to control sedimentation within the well. Horizontal remediation well designers must juggle these same variables, while also considering the difficulties of construction to a greater extent than they would those of a vertical well. Criteria for Hydraulic and Mechanical Well Design 2. Screen slot size: The selection of the screen slot size depends on the type of aquifer and the use of a gravel pack. The screen slot size must be selected to ensure that most of the finer materials in the formation around the borehole are transported to the screen and removed from the well by bailing and pumping during the well- PLASTIC SLOTTED WELL SCREEN - Johnson Well Equipment, Inc Water well industry screen filter manufacturing.
