To improve thin-bed resolution, broadening of the frequency spectrum is required; this has been one of the major objectives in seismic data processing. Recently, many researchers have proposed and shown the applicability of machine-learning-based resolution enhancement and showed their applicability. However, because the performance of machine learning depends on what the model has learned, output from training data with features different from the target field data may be poor. Thus, we have developed a machine-learning-based spectral enhancement technique considering features of seismic field data. We used a convolutional U-Net model, which preserves the temporal connectivity and resolution of the input data, and we generated numerous synthetic input traces and their corresponding spectrally broadened traces for training the model. A priori information from field data, such as the estimated source wavelet and reflectivity distribution, was considered when generating the input data for complementing the field features. Using synthetic tests and field poststack seismic data examples, we showed that the trained model with a priori information outperforms the models trained without a priori information in terms of the accuracy of enhanced signals. In addition, our new spectral enhancing method was verified through the application to the high-cut-filtered data, and its promising features were evaluated through a comparison with well log data.<\/jats:p>","DOI":"10.1190\/geo2020-0017.1","type":"journal-article","created":{"date-parts":[[2021,6,17]],"date-time":"2021-06-17T08:13:00Z","timestamp":1623917580000},"page":"V389-V408","update-policy":"https:\/\/doi.org\/10.1190\/crossmark-policy","source":"Crossref","is-referenced-by-count":18,"title":["Deep learning spectral enhancement considering features of seismic field data"],"prefix":"10.1190","volume":"86","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2580-7866","authenticated-orcid":false,"given":"Yonggyu","family":"Choi","sequence":"first","affiliation":[{"name":"Hanyang University 1 , Department of Earth Resources and Environmental Engineering, Seoul 04763, Korea.
