The Generator-Injector Air Gun is a high-resolution seismic sound source designed to generate repeatable acoustic pulses for offshore geophysical and geotechnical survey operations. The system produces a clean, broadband seismic signal with reduced bubble oscillation, providing enhanced vertical resolution and improved imaging of shallow subsurface geological formations.

The Generator-Injector Air Gun operates by releasing compressed air through a two-stage firing mechanism comprising a generator chamber and an injector chamber. The generator chamber produces the primary acoustic pulse, while the injector chamber suppresses secondary bubble oscillations by injecting a controlled volume of compressed air immediately after the initial discharge. This results in a stable acoustic source signature, improving signal quality and enhancing the resolution of seismic reflections recorded by the marine seismic streamer.

Designed for continuous offshore operation, the Generator-Injector Air Gun delivers reliable and repeatable acoustic performance under a wide range of water depths and seabed conditions. The system interfaces seamlessly with the seismic recording system, marine seismic streamer and integrated navigation software, ensuring synchronized acquisition of high-quality seismic data throughout the survey campaign.

The Generator-Injector Air Gun is widely used for offshore geophysical surveys, marine geotechnical site investigations, pipeline and cable route surveys, offshore wind farm developments, offshore construction support and environmental baseline studies. The system provides high-resolution seismic data for geological interpretation, sediment profiling, geohazard identification and foundation assessments, supporting the planning, design and execution of offshore engineering projects.
