Q compensation PreSDM
This case of reprocessing, from field tape, involving 750 sq km of data suffering from highly-variable absorption and anisotropy due to both structural setting and the presence of thick coals. To image this data we applied DUG MigQ, dramatically enhancing the image in previously 'washed out' data, whilst retaining the integrity of the amplitudes for AVO analysis and inversion.
