Oil shales: compaction, petroleum generation and expulsion
Permian to Miocene oil shales (Torbanite, Posidonia, Messel, Himmetoglu and Condor) from six basins in Australia, Germany and Turkey were studied using a variety of techniques that incorporate petrophysics, geochemistry and petrology. The objectives of this project were to improve understanding of …

Multi-Scale Nanoindentation For Characterization Of Oil Shales
Studies of the effects of polishing techniques, scale of nanoindentation, and petrophysical properties were conducted on both Woodford and Tuscaloosa Marine Shale. Polishing procedures include both an in-house developed, mechanical sample preparation protocol as well as ion beam milling. The …

The analysis of organic matter in oil-shales
The organic matter in five oil shales (three from the Kimmeridge Clay sequence, one from the Oxford Clay sequence and one from the Julia Creek deposits in Australia) has been isolated by acid demineralisation, separated into kerogens and bitumens by solvent extraction and then characterised in some …

High temperature characterization of oil shales: the Green River Formation
Includes bibliographical references.

Sorption of selected inorganic materials on raw and retorted oil shales
Shale oil is an attractive, alternative fuel source for a world in which there is an increasing demand for energy. However, it is necessary to assess the environmental impacts of the shale oil industry before widescale production is begun. Diversity of retorting processes, the subsequent …

Pyrolysis and hydropyrolysis of four Australian oil shales: reactivity comparisons and oil shale characterization
Includes bibliographical references.

Sorption of organic compounds on oil shale materials and sorption of selected chemicals on a Western soil
… of a raw shale (Anvil Points), three spent shales, (Antrim, Oxy 6, and Run 16), and a western soil for three organic compounds (2-Hydroxynaphthalene, 1,2,3,4-Tetrahydroquinoline, and 2,3,5-Trimethylphenol) was evaluated by batch and column sorption studies. In addition, the sorption capacity …

Industrial rotating kiln simulation
… developed to allow the commercial recovery of oil from oil shales. As part of this process, a rotating kiln is used to pyrolyse the organic component of the oil shales. The configuration and application of this rotating kiln is unique and hence previous rotating kiln models cannot be used to …

High-resolution environmental change in the late Jurassic Kimmeridge clay formation
… ranged from 4.5cm per 1000 years for the oil shales to 30-118cm per 1000 years for the coccolith limestone. TOC % ranged from 3-51%, while an average atomic H/C ratio of 1.5 indicated type I to type II kerogens. Optical microscopy found the organic matter to be dominated by amorphous forms …

GEOCHEMICAL CHARACTERIZATION OF THE BONE SPRING FORMATION, DELAWARE BASIN, USING CHEMOSTRATIGRAPHY AND INTEGRATED PETROPHYSICS
… this basin, creating one of the world’s richest oil shales. This formation has lithological sequences that are characterized by repeating carbonate and siliciclastic intervals of a third-order cycle which can largely be correlated to highstand and lowstand systems tracts, respectively. …

Comparison of Heating Methods for In-Situ Oil Shale Extraction
Oil shales are lamellar, non-porous, impermeable hydrocarbon bearing rocks that contain organic matter called kerogen which, when heated at pyrolysis temperature of approximately 600-800 ℉, thermo-chemically decomposes to liberate hydrocarbons. They are at the base of the resource triangle because …

THE APPLICATION OF OXIDATIVE HYDROTHERMAL DISSOLUTION (OHD) TO ORGANIC-RICH SHALES
… explores the application of OHD to organic-rich shales, providing a baseline investigation into how highly aliphatic materials react under OHD conditions, what types of products are created during the process, whether the products are economically valuable, and whether they provide novel …

Spatio-temporal microseismic analysis of the Woodford Shale, Canadian County, Oklahoma
… especially important in low permeability gas and oil shales, where the creation of additional permeability through these fracture treatments is essential to production. However, many applications and analyses of these data are either qualitative in nature or include a large element of …

Geomechanics and elastic anisotropy of the Bakken Formation, Williston Basin
… common in many sedimentary rocks, such as shales. Anisotropy is defined as the spatial alignment of mineral grains, layers, fractures and stresses which causes elastic wave velocity and other elastic properties to vary with direction. There are two types of anisotropy: intrinsic and …
