In most of the western part of the Appalachian basin the organic-matter content of the Devonian shale can be estimated from gamma-ray wire-line logs using the equation: ϕ 0 = (γ B − γ)/A, where ϕ 0 is the organic-matter content of the shale (fractional volume), γ the gamma-ray intensity (API units), γ B the gamma-ray intensity if.

As a non-destructive method, the proton nuclear magnetic resonance (1H NMR) technique with low echo time (TE, e.g., ms) has been increasingly used for characterizing full pore size distribution (PSD) of shales. However, hydrogen contained in some components of the shale skeleton (e.g., kerogen and structural water) also can be detected by NMR in the case of low .

According to estimation, China’s shale gas resource that can be exploited is about 31 × 10 12 m 3 (Wang and Wang, ). In shale gas reservoir, gas exists in three states: as free gas in cracks, as free gas in matrix pore, and as absorption gas (Lane et al., ). Generally, shale.

  Introduction. The recent boom in unconventional oil and gas production from shale has revolutionized the energy landscape in the United States 1 and stimulated both considerable research 2 – 5 as well as environmental and political concerns. Shale is a fine-grained sedimentary rock, composed of solid organic matter (OM) scattered in a mineral . Greater than 33 trillion cubic feet of gas, 68 million barrels of natural gas liquids (NGL), and million bar-rels of water have been produced from the Middle Devonian Marcellus Shale of the. for producing gas from the Devonian shales of the Appalachian Basin. It was prepared in response to a request from Senator Ted Stevens, a member of the Technology Assessment Board. Few data are now available on the distribution and physical and chemical charac-teristics of the Devonian shales of the Appalachian Basin.

Off-gassing studies also continued during this period, including the wells KY-2 and VA   The suite of samples used in this study include specimens of four gas shales, three from the United States (the Marcellus, the Barnett and the Haynesville) and one from an undisclosed location in Poland ().The Monterey shale, while not strictly a shale resource system, is included in the suite to test the effects of the isolation methods on sulfur rich, Type II-S Cited by: An example is provided which utilized this workflow to determine the detailed geology of the Devonian Woodford Shale in Oklahoma.

The Woodford is not only a long‐standing hydrocarbon source rock in large parts of the U.S. Midcontinent but more recently has been designated as one of the more prolific and steady unconventional resource shales.

Devonian–Mississippian strata in the northwestern region of the Western Canada sedimentary basin (WCSB) were investigated for shale gas potential. In the subsurface, thermally mature strata of the Besa River, Horn River, Muskwa, and Fort Simpson formations attain thicknesses of more than 1 km ( mi), encompassing an area of approximately.

Gas From Devonian Shales INTRODUCTION Although it is often presented as a gas source of the future, Devonian shale gas actually has a long production history: the first Devonian shale gas well was drilled in, near Fredonia, NY, and “modest” production from Devonian shale wells began around the s and has continued.

Devonian shales and other unconventional resources can be highly fractured and may have significant amounts of gas stored by adsorption. Conventional experiments are not well suited for characterizing the properties important for describing gas storage and transport in these media.

Previous investigators suggest that more than one half of the gas stored in the Devonian Shales may exist in an adsorbed state.

However, adsorption is considered to be an unconventional mode of gas storage and is not often accounted for in conventional reservoir engineering analysis. This article examines the role that desorption may play in gas production from Devonian Shale.

Shale gas reservoirs are complex, heterogeneous geologic systems that require innovative exploration and completions strategies to produce natural gas economically. Shale gas reservoirs refer to non-buoyancy driven, continuous hydrocarbon plays that are composed of a lithologically diverse group of fine-grained sedimentary rocks that include.

Organic matter in the Devonian gas shales has large surface areas similar to that found in coal. Coal seams are currently being investigated as potential sequestering sites for CO 2 —the most important greenhouse gas.

Naturally occurring organic matter (kerogen) is a microporous material that possesses a very high surface area and, hence, sorption capacity for gas. texts All Books All Texts latest This Just In Smithsonian Libraries FEDLINK (US) Genealogy Lincoln Collection.

Shale Characterization Program. Introduction The Devonian shales of the eastern United States are a potential source for a tremendous volume of liquid and gaseous hydrocarbons. Upper Devonian shales of special significance are the Ohio Shale, New Albany, Chattanooga and others which can be correlated with the Antrim Shale of Michigan.

It was found that the clay mineral, kaolinite, was a major mineral in Well Core No.but no traces of kaolinite were formed in the Devonian shales of New York State.

Unconventional gas exploration began aroundtargeting shale gas resources in the Devonian, Jurassic and Cretaceous black shales, taking advantage of progress in horizontal drilling, fracture. The volume of organic matter in an oil-shale rock, a major variable in the physical and thermal behavior of oil shales, is readily estimated from measured density by means of the relationships developed.

Physical and chemical characterization of Devonian gas shale. Quarterly status report, October 1-Decem   The recent boom in unconventional oil and gas production from shale has revolutionized the energy landscape in the United States 1 and stimulated both considerable research 2,3,4,5 as well as.

This paper will use the term gas shales for the materials currently or potentially yielding the gas, wet gas, and/or liquid petroleum recoverable by hydraulic fracturing although it should be noted that these deposits are also often called tight rock, tight formations, tight oil resources, mudstones, or black shales in the literature (e.g.

Through comprehensive evaluation, it is thought that several shale gas intervals in Sichuan Basin are the practical targets for shale gas exploration and development, and that the Weiyuan.

During this Siluro-Devonian Period, a high subsidence occurs stacked sediment bodies and organic-rich shales were deposited in many places that respectively form important hydrocarbon reservoirs and source rocks throughout North Africa basins and Arabia (Boot et al., ; Lüning et al., ), which lead Algeria to hold the fourth position.

Shales, the most abundant of sedimentary rocks, are valued as the source-rocks and seals to porous petroleum reservoirs. Over the past-twenty years, organic-rich shales have also emerged as valuable petroleum systems (reservoir, seal, and source rocks contained in the same formation).

As such they have become primary targets for petroleum exploration and. Potential natural gas leakage into shallow, overlying formations and aquifers from Marcellus Shale gas drilling operations is a public concern.

However, before natural gas could reach underground sources of drinking water (USDW), it must pass through several geologic formations.

Tracer and pressure monitoring in formations overlying the Marcellus could help detect natural gas. The exponential increase in fossil energy production from Devonian-age shale in the Northeastern United States has highlighted the management challenges for produced waters from hydraulically fractured wells.

Confounding these challenges is a scant availability of critical water quality parameters for this wastewater. Chemical analyses of flowback and produced. The Late Devonian is known for the rapid and global radiation of early forests and soils such as spodosols and alfisols 1,2, development of land plants and soils is hypothesized to have been.

Differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA) have been used for the investigation of Devonian shale. Activation energy values of both raw shale and kerogen concentrate were obtained, and the values are considerably higher than those of the Green River oil shale.

The same is true for the heats of pyrolysis. Specific heats of Devonian shale are. The evolution of Earth’s biota is intimately linked to the oxygenation of the oceans and atmosphere.

We use the isotopic composition and concentration of molybdenum (Mo) in sedimentary rocks to explore this relationship. Our results indicate two episodes of global ocean oxygenation.

The first coincides with the emergence of the Ediacaran fauna, including large. Get this from a library!
