jetting nozzles 72 have incurred too much erosion then another trip plug 104 is dropped into tubing string 14 and pumped down into hydrojetting tool 10 plug 104 has a plurality of wipers 106 to engage the inner surface of tubing string 14 and has a nose 108 on a lower end plug 104 is adapted to engage mandrel 80 on third module sleeve 78 nose 108 is adapted to fit in hole 82 in third module sleeve 78 after plug 104 thus engages third module sleeve 78 further pressure applied will force plug 104 to shear shear pin 87 and move third module sleeve 78 downwardly until it contacts the upper end of second module sleeve 60 this is a second position of third module sleeve 78 when third module sleeve 78 moves to this second position it covers and recloses second jetting nozzles 72 and uncovers and thus opens third jetting nozzles 90 to communication with central opening 56 further jetting with third jetting nozzles 90 may then be carried out to form additional fractures 110 while three modules have been shown herein for hydrojetting tool 10 those skilled in the art will see that additional modules could.
