Abstract:
1. A method comprising: (a) selecting an intelligent switch system and a shunted detonator, wherein the shunted detonator is not an RF-safe detonator and comprises a shunt and a detonator having detonator leads connected to the shunt; (b) assembling a perforating gun system without the shunted detonator at a first location, wherein the first location is not at a well-site location at which the perforating gun system will be used for perforating, and wherein the step of assembling the perforating gun at the first location comprises (c) testing the assembled perforating gun system; (d) transporting the assembled perforating gun system to the well-site location after the step of testing the assembled perforating gun system; (e) transporting the shunted detonator to the well-site location; (f) at the well-site location, removing the shunt from the detonator by disconnecting each of the detonator leads from the shunt; (g) trimming each of the detonator leads so that each trimmed detonator leads is at most eight inches in length; and (h) connecting the trimmed detonator leads to the intelligent switch system of the assembled perforating gun system at the well-site location, wherein
