PRE..R1- DISTItII3L7TIQ 1Lf CYST <br />1. Select number of perforated laterals <br />2. Select perforation spacing = _ ft. <br />3. Since perforations tihoultl not be placed closer than I ft. to <br />the edge of the rtick laver (see p. F-14), subtract 2 ft. from the <br />rock laver length. <br />k L fa�er;enRth " 2 ft. <br />4. Determine the number of spaces between perforations. <br />Divide the length above by perforation spacing and round <br />down to nears-,st whole number. <br />Length pert. spacing = _____ ft. ft. - _.. spaces <br />(3) -_ <br />5. Dumber of perforations is equal to one plus the number of <br />perforation spaces . <br />spaces + I = perforations/lateral <br />6.
