Intriguing features of the North American mid-continent are the widespread and prominent subhorizontal seismic reflectors that are thought to be associated with thick sequences of layered rocks beneath the Phanerozoic cover of the Illinois Basin. The present investigation was an effort to identify and interpret new structural features of the pre-Paleozoic crust at the Ancona Gas Storage field in north-central Illinois. A grid of existing seismic data was reprocessed using the technique of extended correlation.

The reprocessed data was then analyzed using Schlumberger's Petrel visualization software for seismic interpretation and reconstruction of the 2D and 3D crustal geometry. The reprocessing …
