ABSTRACT:
A detonation assembly for an explosive wellhead severing system which employs a battery pack lowerable through a drill string to engage and power the detonation assembly positioned within the well bore. The lowerable unit includes a biased shutter which seals the contacts from discharge of the battery pack by the surrounding fluids. The shuttered unit is lowered into contact with the receiving unit to arm the detonation assembly. Until the power unit is lowered into engagement, the severing system is not armed. In case of malfunction or misfire, the power unit can be retrieved to disarm the detonator assembly. The entire assembly is housed within the drill string to isolate the critical elements from the surrounding environment.
