`
`Lowering Total Cost of Operations Through Higher Perforating Efficiency while
`simultaneously enhancing safety
`A novel selective plug and perf perforating system has been designed, field tested
`and commercialized in 2015. It was created for completing unconventional wells
`using an innovative design that improves the operational efficiency, reduces the
`total cost of operations and enhances reliability and wellsite safety. The new
`purpose engineered perforating gun design features factory preassembled gun
`modules with tandem adapters and a plug-and-go detonator for streamlined
`wellsite assembly, handling, rig-up and disposal. It is specifically engineered for
`pump down frac spreads with parallel frac and perf operations. The purpose
`designed intrinsically safe integrated switch detonator allows constant surface
`communication to all downhole components.
`This paper will briefly describe the technology used and then elaborate on the
`field trial planning, experience and lessons learnt during the over 1.000
`horizontal stages completed using over 10.000 guns since June of 2015.
