【文件名】Seismic frequency control on carbonate seismic stratigraphy: A case study of the Kingdom Abo sequence, west Texas

【纲要】
Conceptual models and real three-dimensional (3-D) seismic data
show that in progradational carbonate platform margin and slope
deposits of the Kingdom Abo reservoir of the Permian basin, west
Texas, primary seismic reflection events do not necessarily follow
clinoformal geologic-time surfaces. The seismic frequency content
of the data controls the dip and architecture of seismic reflection
events. High-frequency seismic data tend to follow thinner, timebounded
clinoform depositional elements (time-stratigraphic units),
whereas low-frequency seismic data tend to image thicker, lowangle
lithofacies units (time-transgressive units). In seismic data of
moderate frequency, both clinoform units and flat lithofacies units
are imaged, creating complex interference patterns that are difficult
to interpret
