the screen should not exceed 1/10 or .1 foot per second. The velocity is calculated by dividing the well yield in gpm by the screen open area in square inches. The slot size of the screen is based on a size analysis of the formation samples. By analyzing the component sizes of the grains in the sample, a grainsize distribution curve can be drawn.
