Abstract

Numerous deepwater, subsalt depth-imaging projects have shown the value of low frequencies. In this study, that observation was exploited through a series of acquisition experiments that were conducted over four fields in the Gulf of Mexico. The purpose was to see how much added benefit could be derived in processing and interpretation when rich low-frequency content was provided at the outset. The experimental methodologies consisted of an integration of steps that generated, preserved, and recorded more low-frequency signal while attacking the accompanying high-amplitude noise. In addition to giving attention to the low end of the spectrum, some of the experiments successfully focused on providing high frequencies as well.
