Background
Approximately 35% of all gun failures are related to wiring or flooding. To improve the overall efficiency of multistage stimulation and perforating, BHP Billiton decided to deploy 402 Fractal* multistage stimulation perforating systems in the Eagle Ford and 65 in the Permian basin as a field test.

BHP Billiton Deploys 467 Fractal System Guns with 99.1% Reliability

Fractal multistage stimulation perforating system provides unmatched safety and efficiency

To mitigate wiring issues in the field, Schlumberger developed the Fractal system, which includes a perforating gun that is preassembled at the manufacturing center, thus reducing the number of electrical connections made manually on location by 85%. The unique modular plug-and-play design also eliminates the O-ring threaded port plug on each gun, minimizing the risk of flooding. The crews experienced a 50% faster turnaround compared with conventional gun systems, which allowed them to focus on other aspects of operational planning and execution, safety, and maintenance while achieving 99.1% reliability.

To improve the overall efficiency of multistage stimulation and perforating, BHP Billiton decided to deploy 402 Fractal multistage stimulation perforating systems in the Eagle Ford and 65 in the Permian basin as a field test. The Fractal system reduces the likelihood of misruns by up to 77% when compared with conventional systems. To address issues experienced by conventional perforating systems, the Fractal system features prewired guns to eliminate wiring connections and errors in the field.
