As part of ongoing research for the Gas Research Institute, new approaches in the use of seismic data have produced promising results. Use of interactive PC-based workstation for interpretation of seismic data from the Appalachian basin has resulted in an improved understanding of the area's geology. Reactivated Precambrian basement fault systems, believed to provide syndepositional control of Devonian shale distribution within the basin, are identifiable in the data. Evidence of an episodic reactivation history occurring throughout the Paleozoic is also apparent. The fault systems are traceable into formations known to provide natural gas production and correlate with trends of higher gas production. The use of color displays of complex signal attributes, calculated using the Hilbert transform of the digital signal, has enhanced the ability to interpret the data. Instantaneous frequency and envelope amplitude anomalies provide evidence of pervasively fractured zones associated with basement faults, thrusts, and overlying zones of flexure. This approach to the interpretation of seismic data thus is an aid to the enhancement of production within the Appalachian basin.
