Abstract

The Quantitative Quality Analysis (QQA) method provides an alternative to subjective analysis of source tests by using analytical measurements on the seismic signal. This is achieved by measuring a number of wavelet attributes of the seismic signal to determine seismic quality. This provides an objective method to determine quality. The QQA method is demonstrated on a vibratory source test where a 60'0001bs M26 vibrator is compared with an 80'0001bs M30 vibrator on a prospect in Australia. The combination of these attributes show the QQA method can clearly differentiate between a 60'0001bs and 80'0001bs vibratory source in a manner which is consistent with expert subjective analysis.
