Air Gun Signature Estimation Using Gun-Mounted Pressure Transducers

F-35 AIR GUN SIGNATURE ESTIMATION USING GUN-MOUNTED PRESSURE TRANSDUCERS SUMMARY Continuous measurement of marine source signatures is now becoming an oil company requirement in offshore petroleum exploration. There is a simultaneous service company requirement to simplify and streamline the air-gun arrays. Pressure measurements at the air gun ports have the potential to address both requirements: they can yield the radiated pressure field while simultaneously eliminating the need for separate time-break sensors. They would also permit pigtails to be eliminated in the air gun array. The algorithm to calculate the pressure field from pressure measurements at the gun ports is demonstrated
