Commercial quantities of gas are likely to occur within closely spaced natural fracture systems close to, or within, organic-rich source beds. Four principal source beds have been identified within the shales of east Ohio. Ranked in order of importance based on geographic distribution and thickness, they are the Huron, Rhinestreet, Cleveland, and Marcellus shales. Within each of these zones, there is believed to be a north-south trending area of most favorable shale lying between immature shales to the west and shales too organically lean to the east. Closely spaced localized fracturing of the Devonian shale sequence is likely to occur along 2 regional trends in east Ohio: the Cambridge arch and the Lake Erie shoreline. Operators drilling within these areas, or near any structurally disturbed area, should evaluate and test shale zones that exhibit indications of being naturally fractured.
