Abstract: 
Seismic
Sequence Stratigraphy
of the Upper Morrow Formation; A Regional Study in the Western Anadarko
Basin
The upper Morrow Formation in the western
Anadarko Basin, northeastern Texas Panhandle, was studied using 360 km
of seismic inversion data integrated with data from 80 wells. The goals
were to use seismic data to interpret the lithologies, depositional environments,
evolving paleogeography, and changing sea level represented by this stratigraphic
interval.
Seismic interval velocity contouring, based upon
wavelet character, and correlation with borehole data provided the basis
for the interpretations. Characteristic seismic signatures of three lithologies,
sandstone, shale, and clayey siltstone, were recognized.
Sandstone anomalies, concentrated at three seismic
horizons, were mapped. The highest and lowest horizons are interpreted
to represent deltaic distributary channel systems, whereas the middle horizon
is interpreted to represent a meandering fluvial system. These seismic
horizons are also interpreted to represent three minor progradational pulses
of 4th- to 5th-order global stratigraphic cycles produced by repeated glaciation
in the southern hemisphere, with possible tectonically generated pulses
superimposed.
