GREEN ENERGETIC CLCP PYROTECHNIC TIME DELAY FUSE
Lead and silver azides are commonly used in commercial and military applications as primary explosives to initiate secondary explosives. Used in a variety of oil and gas industry products and operations, including Tubing Conveyed Perforating (TCP) and wireline perforating operations, these materials are extremely sensitive and potentially hazardous; particularly during manufacturing, loading, assembly, handling and field operations. In addition, lead azide is highly toxic and presents a number of environmental issues during its manufacture and use. Challenged to find a more stable and lead-free alternative energetic material, we developed and currently manufacture 2-(5-chlorotetrazolato)-pentaammine cobalt (III) diperchlorate (CLCP), an energetic material used extensively in oilfield completions to initiate perforating guns. CLCP is a ‘green’ or lead-free, cobalt based material that offers excellent stability at high temperatures. In addition, overall stability and auto ignition values for our CLCP are similar to those for lead azide and are only slightly less than those for silver azide. CLCP is substantially less sensitive to impact/shock and/or friction events when compared to azide-based materials. Designed as a deflagration to detonation transfer (DDT) explosive, CLCP requires a minimum column length and confinement to achieve full detonation. We have demonstrated that CLCP offers a reliable high order detonation when used under these conditions, and is superior to lead azide in a variety of applications.
Currently used in oilfield applications that include initiating perforating tools and Pacific Scientific’s exploding bridge wire (EBW) detonator, CLCP is a proven material and has now been incorporated into our new TCP 6-minute time delay device. This new time delay fuse has been designed specifically for TCP applications, offering a safer and ‘green’ alternative to existing TCP time delays containing lead.
