Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-July 2004

Description: Devonian gas shales underlie approximately two-thirds of Kentucky. In the shale, natural gas is adsorbed on clay and kerogen surfaces. This is analogous to methane storage in coal beds, where CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. Drill cuttings from the Kentucky Geological Survey Well Sample and Core Library are being sampled to collect CO{sub 2} adsorption isotherms. Sidewall core samples have been acqu… more

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: October-December 2002

Description: Proposed carbon management technologies include geologic sequestration of CO{sub 2}. A possible, but untested, strategy is to inject CO{sub 2} into organic-rich shales of Devonian age. Devonian black shales underlie approximately two-thirds of Kentucky and are generally thicker and deeper in the Illinois and Appalachian Basin portions of Kentucky. The Devonian black shales serve as both the source and trap for large quantities of natural gas; total gas in place for the shales in Kentucky is est… more

NATURAL GAS RESOURCES IN DEEP SEDIMENTARY BASINS

Description: From a geological perspective, deep natural gas resources are generally defined as resources occurring in reservoirs at or below 15,000 feet, whereas ultra-deep gas occurs below 25,000 feet. From an operational point of view, ''deep'' is often thought of in a relative sense based on the geologic and engineering knowledge of gas (and oil) resources in a particular area. Deep gas can be found in either conventionally-trapped or unconventional basin-center accumulations that are essentially large … more

Transition metal catalysis in the generation of petroleum and natural gas. Progress report, [1992--1993]

Description: A new hypothesis is introduced for the generation of petroleum and natural gas. The transition metals, activated under the reducing conditions of diagenesis, are proposed as catalysts in the generation of light hydrocarbons. The objective of this proposal is to test that hypothesis. Transition metals (Ni, V, Ti, Co, Fe), in kerogen, porphyrins, and as pure compounds, will be tested under catagenic conditions for catalytic activity in the conversion of normal paraffins and hydrogen into light hy… more

Organic/Inorganic interactions of nitrogen in oil fields Geochemistry. Part 1, Geochemistry: Final report, September 15, 1991--March 15, 1994

Description: This research examines the nitrogen isotopic composition of fixed-NH{sub 4} in order to test the hypothesis that NH{sub 4}{sup +} is released from organic matter during hydrocarbon generation and can be incorporated in diagenetic clay minerals along migration conduits. Anomalously high levels of NH{sub 4}-substitution recognized in hydrocarbon bearing sandstones may indicate paths of hydrocarbon migration long after the hydrocarbons have moved on toward a trap. This is important because most of… more

Analysis of high pressure oil shale Hugoniots

Description: A collection of low and high stress level Hugoniot data for a low kerogen content, porous Anvil Points oil shale are analyzed with the P-..cap alpha.. model to give a Hugoniot for kerogen free shale. The P-..cap alpha.. model suggests an ''elastic'' yield stress, P/sub e/, of 0.5 GPa and a solid density complete compaction pressure, P/sub s/, of 10.0 GPa. Knowledge of this behavior permits the calculations of the in situ, ''effective,'' Hugoniot of kerogen from extensive Hugoniot data for vario… more

Analysis of low stress oil shale Hugoniots

Description: Analysis of low stress Hugoniot data on Anvil Points oil shale was accomplished through careful categorization of data depending upon density. Density is directly related to kerogen content and kerogen content is a strong variable in determining the Hugoniot. For a given density (kerogen content), the shock velocity-particle velocity data show a minimum in shock velocity believed related to yielding in the rock constituent of the oil shale. Low stress Hugoniot data blend smoothly with high pres… more

Hugoniots of Colorado oil shale

Description: Standard experimental shock wave techniques were used to obtain Hugoniots of Anvil Points oil shale as functions of richness and orientation in the pressure regime encountered in the near-field region of an explosion. The shock response was found to be sensitive to kerogen content but independent of bedding orientation relative to the direction of shock propagation. A two-component model combining the inferred dynamic parameters for the end members (kerogen and mineral matrix) is adequate to pr… more

Optical constants of kerogen from 0. 15 to 40. mu. m: Comparison with meteoritic organics

Description: Kerogens are dark, complex organic materials produced on the earth primarily by geologic processing of biologic materials, but kerogens have chemical and spectral similarities to some classes of highly processed extraterrestrial organic materials. Kerogen-like solids have been proposed as constituents of the very dark reddish surfaces of some asteroids and are also spectrally similar to some carbonaceous organic residues and the Iapetus dark material. Kerogen can thus serve as a useful laborato… more
