This idea has come to be known as spectral decomposition. In recent years, many spectral decomposition techniques have been developed and utilized for stratigraphic analysis and direct hydrocarbon detection. With the refined spectral decomposition techniques now available, the low-frequency shadow beneath gas reservoirs is another old idea that has renewed importance and interest in the exploration community. Almost a decade ago, Dan Ebrom studied a variety of possible mechanisms for the low-frequency shadow and why it might be associated with hydrocarbons. He presented his analysis at the 1996 SEG Summer Research Workshop.<\/jats:p>","DOI":"10.1190\/1.1786898","type":"journal-article","created":{"date-parts":[[2004,8,13]],"date-time":"2004-08-13T09:00:34Z","timestamp":1092387634000},"page":"772-772","source":"Crossref","is-referenced-by-count":108,"title":["The low-frequency gas shadow on seismic sections"],"prefix":"10.1190","volume":"23","author":[{"given":"Dan","family":"Ebrom","sequence":"first","affiliation":[{"name":"currently at BP Exploration and Technology Group 1 , Houston, Texas (formerly with Allied Geophysical Laboratories, University of Houston, Texas, U.S.)"}]}],"member":"186","container-title":["The Leading Edge"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.geoscienceworld.org\/seg\/tle\/article-pdf\/23\/8\/772\/7395031\/1.1786898.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.geoscienceworld.org\/seg\/tle\/article-pdf\/23\/8\/772\/7395031\/1.1786898.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T18:20:14Z","timestamp":1765218014000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.geoscienceworld.org\/tle\/article\/23\/8\/772\/59813\/The-low-frequency-gas-shadow-on-seismic-sections"},"secondary":[{"URL":"https:\/\/pubs.geoscienceworld.org\/tle\/article\/23\/8\/772\/59813\/the-low-frequency-gas-shadow-on-seismic-sections","label":"geoscienceworld"},{"URL":"http:\/\/tle.geoscienceworld.org\/cgi\/doi\/10.1190\/1.1786898","label":"geoscienceworld"}]},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,8,1]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2004,8,1]]}},"URL":"https:\/\/doi.org\/10.1190\/1.1786898","relation":{},"ISSN":["1070-485X"],"issn-type":[{"value":"1070-485X","type":"print"}],"subject":[],"published-other":{"date-parts":[[2004,8]]},"published":{"date-parts":[[2004,8,1]]}}}
