Abstract
A method includes assembling a first tool string to include at least one original perforating gun and an original gun switch in communication with the original perforating charge, and inserting the first tool string into a first wellbore. The method also includes retrieving the first tool string from the first wellbore and recovering the original gun switch from the first tool string, assembling a new tool string to include at least one new perforating gun, wherein the new tool string further includes the recovered original gun switch whereby the original gun switch is in communication with the new perforating charge, and inserting the new tool string into at least one of the first wellbore and a different wellbore, and delivering a signal to the original gun switch to initiate detonation of the second perforating gun.
