The 2 1/8-in PowerSpiral Nova extradeep spiral-phased capsule gun perforating system is a retrievable system designed for through-tubing operations. As a capsule gun, the 2 1/8-in PowerSpiral Nova system enables using the maximum charge size, which in combination with rock-optimized PowerJet Nova extradeep penetrating shaped charges and strategically placed shock-absorbing material delivers perforations capable of the highest well productivity for the gun system size.

PowerJet Nova charges are so effective because they are the result of laboratory research involving hundreds of shaped charge test shots into a broad range of stressed rocks, including extreme values of rock strength. API RP 19B Section 1 performance data and additional stressed-rock testing document the improved efficiency of the charges’ explosive energy transfer to the perforating jet. In addition to increasing penetration over previous-generation deep penetrating shaped charges, PowerJet Nova charges deliver up to 50% more formation contact for more effective stimulation treatments and increased drainage contact for greater productivity.

The proven design of the PowerSpiral spiral-phased capsule gun perforating system used by the 2 1/8-in PowerSpiral Nova system employs shock-absorbing material between the charges. This attenuates shock waves during detonation to reduce charge-to-charge interference and also minimize shock waves in the wellbore. The effects are significant in increasing the performance of the shots across the wellbore.

The 2 1/8-in PowerSpiral Nova system is compatible with all wireline, LIVE Digital Slickline Services, and mechanical slickline conveyance.
