Determine the Number of Perforation Spaces. Divide the Length of Laterals by the Perforation Spacing and <br />round down to the nearest whole number. <br />Number of Perforation Spaces - 60.5 ft 3.0 it = 20 Spaces <br />g. Number of Perforations per Lateral is equal to 1.0 plus the Number of Perforot fon Spaces. Check table below <br />to verify the number of perforations per lateral guarantees less than a 10% discharge variation. The value is <br />double with a center manifold. <br />Perforations Per Lateral = 20 Spaces + 1 = 21 Perfs.
