New explosive detonator improves worksite safety
The industry has long been concerned about preventing unwanted detonation of explosives around work sites or downhole, because of inadvertent contact with stray electrical currents, impacts, heat, etc. To answer the challenge of developing a safer, more economical system to use in explosive perforating, cutting and severing jobs, Halliburton Energy Services has introduced the Rig Environment Detonator (RED). The new electroexplosive device utilizes semiconductor bridge technology and a special deflagration-to-detonation technique involving secondary, not primary, explosives. Three independent testing authorities in the US and the UK have recognized the improved safety of the system. Details of available conventional detonators ranging from the earliest blasting caps to very safe, but expensive, systems; design/testing of the new device; and case histories of its use are presented and illustrated in SPE paper 36637, ``Unique electrical detonator enhances safety in explosive operations: case histories``. This paper contains extracts from the SPE paper.
