Sand, Screens and Open Area - JKA Well Drilling Slot size means almost as much as putting a screen in in the first place. If we size the screen too small, the well doesn't make as much water as it could, if we size it too big, it will take FOREVER to develop the fine particles out of the 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-
DESIGN AND INSTALLATION OF MONITORING WELLS - US EPA
Designing horizontal well screen begins after the consulting engineer determines that the project site, the contaminant, and the remediation goals are conducive for a Horizontal Remediation Well system. Once the horizontal well screen design is completed, a horizontal well pipe slotter is contacted and given the engineered specifications. NRC015 - Driscoll, F.G. (1986), Groundwater and Wells ...
The slot size in the coarse material should not be more than double the slot size for the overlying finer material. Doubling of the slot size should be done over screen increments of 2 ft (0.6m) or more. Figure 5.11 (a) Stratigraphic section that will be screened with slot sizes corresponding to various layers.
Well Construction | Casing (Borehole) | Pipe (Fluid Conveyance) Well Screens A well screen is a filtering device that attaches to the bottom length of casing and allows water to move into the well while keeping the majority of sand and gravel out of the well.E.oh. Slot machine - Wikipedia The video slot machine is a more recent innovation, with no moving parts at all – instead a graphical representation of one appears on screen.
