Abstract:

The Lower Silurian Clinton section in east-central Ohio is a clastic wedge of sandstones, shales, and carbonates. Previous studies have shown that the Clinton section was deposited as a delta prograding westward over reworked clastics of the Ordovician Queenston Shale.

Geophysical log data were used to construct total Clinton sandstone and sandstone cleanliness maps of the delta margin. Clean-sand maps show the distribution of sand and shale in an offshore bar system in west-central Holmes County. Similar studies in adjoining counties indicate an extension of this bar system, which coincides with the Newburg pool in southern Medina County. Stratigraphic cross sections show the intertonguing relationship of sand, shale, and carbonate lithosomes typical of a deltaic system. The clastics of the upper Cabot Head grade westward into calcareous sands and thickening carbonates. Slice maps show the distribution of these deposits during time.

Production of oil and gas in Holmes County has been concentrated along the north-trending thick sands of the delta-margin bar system. Sand isopach maps, cross sections, and a porosity foot map show the distribution of thinner fluvial and fluvial delta-margin sands in western Holmes County.
