| Popis: |
We have developed a new air-gun that optimizes the useful seismic output while limiting any environmental effects from unnecessary high-frequency emissions. We regulate the output at the air-gun’s ports by controlling the motion of the mechanical components that release air from an internal chamber. Our design process is based on advanced fluid-dynamics simulation to optimize acoustic performance, and mechanical finite-element simulation to ensure structural robustness. This is validated by physical tests to calibrate the models, improve reliability, and characterize the final acoustic performance. Having carried out extensive testing on prototypes, we plan to introduce the air-gun into arrays for a commercial seismic survey. |
