Method for detecting air gun faults in a marine seismic source array

摘要

Abstract A method for determining a fault in a seismic air gun includes comparing a near field seismic signal measured during operation of the air gun to a reference near field signal and determining the existence of a fault in the air gun when a difference between the measured near field signal and the reference near field signal exceeds a selected threshold. 1 ,-12 20 20 20 20 18 21 21 21 21 19 1 18 18 14 14 14 14 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22
