Qualitative and Quantitative Analysis of Dibenzofuran, Alkyldibenzofurans, and Benzo[b]naphthofurans in Crude Oils and Source Rock Extracts

Outside Publication: Energy & Fuels
​Dibenzofuran (DBF), its alkylated homologues, and benzo[b]naphthofurans (BNFs) are common oxygen-heterocyclic aromatic compounds in crude oils and source rock extracts. A series of positional isomers of alkyldibenzofuran and benzo[b]naphthofuran were identified in mass chromatograms by comparison with internal standards and standard retention indices.

Coal and Petroleum Resources in the Appalachian Basin: Distribution, Geologic Framework, and Geochemical Character

USGS Publication: Professional Paper 1708
Fossil fuels from the Appalachian basin region have been major contributors to the Nation’s energy supplies over much of the last three centuries. Appalachian coal and petroleum resources are still available in sufficient quantities to contribute significantly to fulfilling the Nation’s energy needs. Although both conventional oil and gas continue to be produced in the Appalachian basin, most new wells in the region are drilled in shale reservoirs to produce natural gas...

Structural degradation of Thar lignite using MW1 fungal isolate: Optimization studies

Outside Publication: International Biodeterioration & Biodegradation
Biological degradation of low-rank coals, particularly degradation mediated by fungi, can play an important role in helping us to utilize neglected lignite resources for both fuel and non-fuel applications. Fungal degradation of low-rank coals has already been investigated for the extraction of soil-conditioning agents and the substrates, which could be subjected to subsequent processing for the generation of alternative fuel options, like methane...

Development, evolution, and destruction of the saline mineral area of Eocene Lake Uinta, Piceance Basin, western Colorado

USGS Publication: Scientific Investigations Report 2013–5176
​Halite and the sodium bicarbonate mineral nahcolite were deposited in Eocene-age saline Lake Uinta in the Piceance Basin, northwestern Colorado. Variations in the areal extent of saline mineral deposition through time were studied using descriptions of core and outcrop.

In-Place Oil Shale Resources of the Mahogany Zone, Green River Formation, Sorted by Grade, Overburden Thickness, and Stripping Ratio, Piceance Basin, Colorado, and Uinta Basin, Utah

USGS Publication: Fact Sheet 2015-3005
A range of geological parameters relevant to mining oil shale have been examined for the Mahogany zone of the Green River Formation in the Piceance Basin, Colorado, and Uinta Basin, Utah, using information available in the U.S. Geological Survey Oil Shale Assessment database.
