Patent ID: 8905125

Claim:
A method for treating a well, comprising: running a drill string down the well, the drill string comprising a conduit and a bottom hole assembly including an abrasive perforating tool; wherein the perforating tool comprises at least one nozzle and first and second sleeves sequentially movable from a non-deployed position to a deployed position to provide first, second, and third flow paths through the perforating tool, so that when the first and second sleeves are in the non-deployed position, fluid passes through the perforating tool through a first flow path bypassing the at least one nozzle, so that when the first sleeve is deployed and the second sleeve is not deployed, fluid entering the perforating tool is diverted entirely to the at least one nozzle through the second flow path, and so that when the first and second sleeves are deployed, fluid passes through the perforating tool through a third flow path bypassing the at least one nozzle; without deploying either the first or second sleeve, passing fluid through the drill string without perforating; after passing fluid through the drill string without perforating, deploying the first sleeve to direct fluid through the perforating tool along the second flow path; after deploying the first sleeve, abrasively perforating the well without withdrawing the tool string; after abrasively perforating the well, deploying the second sleeve in the perforating tool; and after deploying the second sleeve, passing fluid through the tool string without perforating and without withdrawing the tool string.
