...Mark A. Pearce; Beverly J. Seyler Abstract The gas-bearing sandstones of the Medina Group in western New York are the basal Whirlpool Sandstone and the Grimsby Sandstone. Toward the west, these are separated by the Cabot Head Shale and the Manitoulin Limestone. Farther east, the Grimsby overlies...

Continental sedimentation occurred during lower Whirlpool deposition and upper Grimsby deposition. The change from transgressive to regressive tendencies is marked...

The thickest sandstones, and most important hydrocarbon reservoirs, are in the Grimsby Sandstone, which is interpreted as a highstand systems tract with basinward-prograding deposits formed during a normal regression. Three major de-positional systems...

The Llandovery succession of the Michigan Basin measures between 140 m and 265 m thick and is represented by three lithostratigraphic groups: the Cataract (Manitoulin formation and Cabot Head Shale), the Burnt Bluff (Lime Island, Byron...

Visual inspection reveals trends common to the isopach maps and estimated-net gas reserves. Thus, stratigraphic...
