Technical Program Expanded Abstracts are papers presented at the Society of Exploration Geophysicists' Annual Meetings and International Expositions. Most of these expanded abstracts are four pages long and include figures. These abstracts undergo a review for selection purposes but are published as presented by the authors. The archive covers papers presented at each SEG Annual Meeting since 1982. The archive also contains over 800 papers per year from 2008 to the present including over 300 associated presentation files available via the Multimedia icon displayed with the associated paper.
