..., Kentucky, were completed in the Berea and Devonian shale formations, and each formation was stimulated separately. About half the wells were stimulated with nitrogen foam containing proppant; the other treatments consisted of nitrogen only. These wells were drilled in the 1990s and sufficient production...

... In 1991, GRI began a research program involving special coring, logging, and testing in the Devonian shale section of two wells in Pike County, Kentucky: Ashland FMC No. 69 and No. 78. A total of 445 feet of conventional oriented core was cut while drilling with dry air in the Transition/L. Huron...

..., coalbed methane and Devonian shale gas, these incentives were designed to reduce risk and improve project economics of these "high-cost" gas resources. Despite the fundamental transformation of the gas industry over the past decade, however, the Section 29 credit has not changed in scope or mechanism...

... Abstract The use of X-ray computed tomography scanning with a dual scan technique to study gas storage and transport in Devonian shales is investigated. Dynamic scanning experiments are performed at various gas pressures. Krypton gas is used as the saturating fluid, and its validity in modeling...

... ABSTRACT The borehole television camera has greatly assisted the identification and evaluation of potentially productive zones within the Devonian Shale sequence within the Appalachian Basin. The application of this tool in conjunction with open hole logs has helped identify and categorize...

... Abstract A detailed study of the thermophysical properties of Devonian shales from the central and eastern United States has been carried out. The properties encompass a wide spectrum of material properties such as thermal conductivity, thermal diffusivity, specific heat, dielectric constant...

... Abstract Available data on foam frac treatments from DOE/industry cooperative ventures and the state-of-the-art in the formulation of foam fluids for hydraulically fracturing the Devonian shale are reviewed and discussed in light of an engineering measurement of factors affecting cleanup...

... massive fracturing treatments were not conducted in this area until recently. This paper will deal with six large volume treatments that have been conducted in the Devonian Shale and the Clinton formations in this area. The Devonian Shale is a massive siltstone deposition spread throughout West Virginia...

... Abstract A project has been initiated by the Energy Research and Development Administration (ERDA) to characterize gas-bearing shale formations and develop improved gas-extraction technology for these low-permeability "tight" reservoirs. The Eastern Devonian Shales are very prominent...
