Shale geology.

For example, micro-seismic surveys of shale gas wells in the eastern United States show that fractures are separated from groundwater by more than a mile of rock - a distance as deep as the Grand Canyon. We use pre-drilling and planning activities to identify areas of potential environmental, geologic or archaeological sensitivity.

Shales are formed by dewatering and compaction of muddy sediments deposited on the sea bottom. Fresh broken pieces of the Ohio Shale give off a sulfurous petroleum odor. Ohio Shale is an organic-rich shale and a good source for oil and gas in the subsurface. Its vertical joints are the pathways for oil and gas migration (fig. 1A).The only difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms.

These perforations allow communication between the well and the shale formation for hydraulic fracturing fluids to be injected into the reservoir rock surrounding the lateral at high pressure. The perforating is done in relatively short segments of the well, typically 150-250 feet long, which are known as stages.

The Chagrin Shale is a shale geologic formation in the eastern United States that is approximately 365 million years old. The Chagrin Shale is a gray shale that begins thin and deep underground in north-central Ohio. As it proceeds east, the formation thickens, rises to the surface, and contains greater amounts of siltstone.
