17. A method comprising:
installing an explosive assembly within a downhole release tool, wherein the explosive assembly comprises: a housing assembly; an explosive charge disposed within the housing assembly; an outer electrical interface along an outer surface of the housing assembly; and a detonator switch disposed within the housing assembly and operable to detonate the explosive charge, wherein the detonator switch is electrically connected with the outer electrical interface, and wherein installing the explosive assembly within the downhole release tool comprises inserting the explosive assembly as a single unit within an internal space of the downhole release tool such that the outer electrical interface contacts an inner electrical interface along an inner surface of the downhole release tool; and
when the downhole release tool is connected between a first portion of a downhole tool string and a second portion of the downhole tool string and the downhole tool string is conveyed within a wellbore, transmitting from a wellsite surface a control signal to the detonator switch to detonate the explosive charge to sever a support member connecting together a first portion of the downhole release tool and a second portion of the downhole release tool to therefore disconnect the first portion of the downhole release tool and the second portion of the downhole release tool from each other and thus disconnect the first portion of the downhole tool string and the second portion of the downhole tool string from each other.
