may be substituted with a packer similar to packer 119 by landing a ball against a seat below where packer 109 is shown a u201c completion string u201d is run into the well consisting of a locator snap latch seal assembly 110 tubing spacer 114 frac module 108 tubing spacer 114 frac module 107 tubing spacer 114 frac module 106 tubing spacer 114 a service production packer not shown and work string or production 115 the length of tubing spacers 114 are made to position the frac modules 106 107 and 108 between the producing zones 111 112 and 113 the single trip completion string is landed in sump packer 109 the location of sump packer 109 is based on logs of the zones so that all equipment could be spaced out properly therefore by locating the completion assembly on the sump packer 109 all frac modules 106 107 and 108 will be properly positioned in the well snap latch seal assembly 110 can be used to verify position of the system before setting any of the packers 117 118 and 119 the locator snap latch seal assembly 110 seals in the sump packer 109 and will locate on the sump packer the locator snap latch seal assembly 110 is designed to allow pulling of the work string 115 to get a load indication on the sump packer 109 and then snap back in and put set down weight on the sump packer 109 the above steps are common in the art of completing wells at this point in time the completion hardware shown in fig4 is properly positioned around all the zones to be stimulated all stimulation equipment.
