SeismicRF-Safe System
Solving the problem of unintentional firingAlthough much time and effort go into training personnel and implementing safety procedures, oilfield accidents involving wireline perforating still happen. Frequently they are caused by the unintentional premature firing of explosives caused by extraneous electricity – stray current or voltage, static electricity or high-frequency irradiation. Ideally, a detonator should be immune to any type of extraneous electricity but unfortunately, this is not possible with conventional electric detonators. But now DYNAWELL has taken a huge step forward to creating a safe environment with a solution that provides protection against all kinds of extraneous electricity.
Electronics safer than electrics
The secret of DYNAWELL’s RF-Safe Perforating System is its electronic digital-coded detonator. Unlike conventional electric detonators, this electronic detonator uses a built-in capacitor to fire the fuse head. Charging and firing are controlled via an electronic system integrated into the microprocessor of each detonator. Only when this chip receives a digital-coded signal can the capacitor be charged to the required firing voltage. After charging the capacitor, an additional specific digital code must be delivered to the detonator to release an electronic switch, allowing the capacitor to discharge and initiate the fuse head.
- Safe against RF: unparalleled safety against high-frequency irradiation
- Safe against stray current and voltage: far superior to electric detonators
- Safe against static electricity: unaffected by electrostatic discharges, e.g. in the human body
- Safe against induced power caused by lightning: immune to stray current from a lightning strike when the gun system is in the hole
