The Model SR ADT is the latest addition to ICSI’s family of Addressable Disconnect Tools. This tool uses the same tried-and-true releasing mechanism as previous models, but incorporates some exciting new features:
Thanks to our Detonator Cartridge System (patent pending), detonator swaps are now incredibly quick and simple! The CCL Adapter (CCLA) is unthreaded from the Actuator, the old Detonator Cartridge is slid out of the Actuator, the new Detonator Cartridge is slid into the Actuator, and the CCLA is again threaded into the Actuator... THAT’S IT! The Detonator Cartridges themselves can be reused many times. This allows the engineers on location to work ahead, replacing the detonators in the Cartridges before they are needed. The loaded Cartridges can then be stored safely with our Shunt Circuit Harness installed.
The Model SR ADT can be used with any select-fire perforating system. It will accept any type of presently known addressable switch. The Model SR ADT utilizes an A-105 detonator. When being used with DynaEnergetics DynaSelect and DynaStage systems, the SR-ADT utilizes a special DE Cartridge to house DynaEnergetics detonators.
The ADT is pull tested to 28,000 lbs, with the weak point being at the Separation Collar. However, the tool is designed such that no weight or compression is on the Separation Collar when the tool is under hydrostatic pressure.
NOTE to EB-style gun system users:
The Model SR ADT cannot currently be adapted to run with EB-style systems. The Model CF ADT (page 1) must be run with ICSI’s Addressable Switch to accommodate EB-style systems. However, components from the Model SR ADT can be used on the Model CF ADT to make the tool shorter and more rugged.
