'''Seismic facies''' are "mappable, three dimensional seismic units composed of groups of [[Reflection configuration patterns|reflections]] whose parameters differ from those of adjacent facies units”.<ref name=ch21r31>Mitchum, R., M., Vail, P., R., Sangree, J., B., 1977, [http://archives.datapages.com/data/specpubs/seismic1/data/a165/a165/0001/0100/0117.htm Seismic stratigraphy and global changes in sea level, part 6: stratigraphic interpretations of seismic reflection patterns in depositional sequences], in Payton, C., E., ed., Seismic Stratigraphy and Applications to Hydrocarbon Exploration: [http://store.aapg.org/detail.aspx?id=1157 AAPG Memoir 26], p. 117–133.</ref> Seismic facies analysis is the description and interpretation of seismic reflection parameters, such as configuration, continuity, [http://wiki.seg.org/wiki/Dictionary:Amplitude amplitude], and [http://wiki.seg.org/wiki/Dictionary:Frequency frequency], within the stratigraphic framework of a depositional sequence. Its purpose is to determine all variations of seismic parameters within [[third-order sequences]] and their systems tracts in order to determine [[lateral]] lithofacies and fluid type changes.<ref name=ch21r44>Vail, P., R., 1987, [http://archives.datapages.com/data/specpubs/oversiz2/data/a188/a188/0001/0000/0001.htm Seismic stratigraphy interpretation procedure], in Bally, A., W., ed., Atlas of Seismic Stratigraphy: [http://store.aapg.org/detail.aspx?id=478 AAPG Studies in Geology No. 27], p. 2.</ref> Of these parameters, [[Reflection configuration patterns|reflection pattern]] geometries are perhaps the most useful for calibration with lithofacies interpreted from [[Quick-look lithology from logs|well logs]], [[Core description|cores]], and [[Mudlogging: drill cuttings analysis|cuttings]].
