Abstract: Methods and systems for efficient compaction sweep and seismic data sweep are disclosed. One method comprises sweeping the source through a range of source frequencies for one or more compaction sweeps, each compaction sweep comprising a compaction sweep amplitude-frequency-time relationship; sweeping the source through a range of source frequencies for one or more data sweeps, each data sweep comprising a data sweep amplitude-frequency-time relationship; and correlating seismic responses only with the data sweeps. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
