Chattanooga shale
Tennessee has no significant proved natural gas reserves and its natural gas production is small. 87,88 Most of the state's natural gas-producing wells are located in northeastern Tennessee on the Cumberland Plateau. 89 Natural gas exploration permits issued in the past decade have focused on exploration in the Chattanooga Shale play, which ...The Chattanooga Shale has a very high organic content. Without providing a source, Mr. Froede argues that the presence of organic matter is due to debris: I suggest that the Chattanooga Shale, as found in Tennessee, originated as a volcaniclastic deposit which mixed with organic debris. Conant and Swanson (1957, p.

Although the Chattanooga Shale contains other burrows that postdate the liquid-substrate burrows discussed in this paper (e.g., Planolites, Teichichnus, and Chondrites), these will not be discussed in this contribution.

Fractures within the Chattanooga Shale offer potential insight into subsurface fracturing, as well as local and regional stress environments. To account for lithological variation several close-up scanned images were collected from ...The Chattanooga shale is a black to gray shale, which is exposed in many places from Alabama and Georgia to Missouri and Oklahoma, and continues in the subsurface into Kansas. Throughout Tennessee, Kentucky, Missouri, and Arkansas, the Chattanooga is 15 to 50 feet thick in most places, but formations in adjoining states with which it has been ...
The geologic model for the AU assumes that petroleum resources remain trapped within the shale following petroleum migration. For most of the AU, organic matter within the Woodford Shale and Chattanooga Shale is thermally mature with respect to petroleum generation as shown by vitrinite reflectance values between 0.6 and 1 percent.These conditions were similar to those that prevailed during deposition of the Chattanooga Shale (Late Devonian in central Tennessee (Conant and Swanson, 1961, p. 56, 62). The gray marine shale in the upper part of the Heebner indicates that a well-aerated and presumably, gradually deepening sea persisted during deposition of the Plattsmouth ...The Late Devonian Chattanooga Shale of Tennessee (Fig. 1) has primarily been studied from a sedimentological perspective (Schieber, 1994, Schieber, 1998) and contains the same types of black shales as observed in other areas of the Illinois and Appalachian Basins. In central Tennessee it was deposited within reach of storm wave base, an ...…

The Chattanooga Shale has a maximum thickness in the Black Warrior Basin of approximately 30 ft. Total organic carbon values for the Chattanooga Shale in northern Alabama average about 16.3, and organic matter consists of type I and type II kerogen. A thin black shale at the top of the Stones River Group in northern Mississippi, whichPolychaete worms have adapted to quite low ambient oxygen concentrations, and are in many cases involved in black shale bioturbation. When oxygen is low they tend to live mainly in the very watery/soupy surface sediment (water contents 70-80%), and swim through the sediment rather than engaging in building of actual tunnels.

Although the Chattanooga Shale containA decrease in shale proportion can reflect eithe Fracking is a method of extracting natural gas from shale deep underground - in Tennessee, it's called the Chattanooga Shale. Fluids are sent down a well at high velocity and pressure. That force forms cracks in the rock layers, freeing up pockets of natural gas. The absence of the Hannibal shale and the Louisiana limestone The main producing formation is Corniferous, and production is encountered within a few feet of the Chattanooga shale. The stratigraphy of the pay is probably the same as that of Warren and Allen counties. Amber oil occurs just above the Chattanooga shale in the Austin pool and is known in small quantities elsewhere at a somewhat higher level.Chattanooga Shale.
