Abstract
ABSTRACT: Enhancement of Geological Features on Barnett Shale
by the Application of Spectral Decomposition and
Spectral Inversion, Shackleford County, Fort Worth
Basin, Texas, USA
Using Spectral Decomposition and Spectral inversion concepts it is possible to go beyond 
seismic
resolution and get results that can be
interpreted more objectively and accurately on the Barnett Shale in the Fort Worth Basin. This research focused in applying spectral
decomposition and spectral inversion on a 3D seismic data from the Shackelford County, Texas, USA, to define stratigraphic and structural
elements that cannot be seen with conventional seismic data.
It is shown that spectral decomposition and spectral inversion helped identify faulting patterns, also, proved to be a powerful tool to identify carbonate features on this part of the Barnett Shale region.
The combination of frequency cubes on a RGB color coded helped to identify more accurately and faster the presence of these geologic elements.
Uses of these techniques improved the vertical resolution from 115 ft. to 50 ft. in this area leading interpreters to understand the
characteristics of the Barnett Shale in terms of seismic signature including faulting and fractures that are bellow seismic resolution
