The ACTive OptiFIRE CT real-time selective perforating and activation system's perforating guns can be activated up to 10 times with precise downhole depth and hydrostatic pressure control—all in a single run. The surface system selectively fires individual guns from the bottom up without pumping fluid, and detonation is confirmed in real time through built-in sensors, such as pressure, temperature, casing collar locator, and accelerometer—improving overall safety. The system does not require a ball drop or a pressure pulse system to detonate and can be used with a wide range of perforating guns. Unlike conventional perforating heads operated by hydraulics, the ACTive OptiFIRE system does not require pumping fluid for activation and wellbore fluid circulation, making it well-suited for subhydrostatic wells, high-flow-rate wells, and unstable or fluid-sensitive formations.
