ENVIRONMENTAL REPORT: STIMULATION OF DEVONIAN SHALE FORMATIONS IN OHIO, NEW YORK, AND MARYLAND

摘要

This formation, underlying over 250,000 mi of the U.S., is known to contain huge volumes of natural gas, but to date has yielded only marginal amounts due to the low permeability of the rock. The objective of this project is to test various methods of fracturing the rock, and thus "stimulating" greater yields, in hitherto untested areas of the shale.nThe actual sites within the target areas have not been selected. However, each stimulation will involve clearing and leveling a 2-3 ac pad, drilling and coring the well, and fracturing the shale interval by one of several hydraulic or explosive methods.
