Measured reflectance suppressed by thin-film interference of crude oil smeared on glass

As on vitrinite in coal or petroliferous rocks

Outside Publication: Society for Organic Petrology Newsletter
The tool of measuring "vitrinite reflectance" under a microscope has great value in petroleum exploration and coal utilization, and the reflectance is a simple number, such as 1.4% Ro, with some slight variations depending on technique. This report analyzes here just one factor, "smear" of crude oil on the polished surface (from the sample), which may reduce reflectance because of thin-film interference.

A Critical Review of Published Coal Quality Data From the Southwestern Part of the Powder River Basin, Wyoming

USGS Publication: Open-File Report 2011–1148
A review of publicly available coal quality data during the coal resource assessment of the southwestern part of the Powder River Basin, Wyoming, revealed significant problems and limitations with those data. The review processes demonstrated why it is always preferable to research and evaluate the circumstances regarding the sampling and analytical methodology from the original data sources when evaluating coal quality information, particularly if only limited data are available.

Assessment of Undiscovered Oil and Gas Resources of the Devonian Marcellus Shale of the Appalachian Basin Province

Press Release & Publication
In 2011, the USGS completed an assessment of the undiscovered oil and gas potential of the Devonian Marcellus Shale within the Appalachian Basin Province of the eastern United States. The Marcellus Shale contains about 84 trillion cubic feet of undiscovered, technically recoverable natural gas and 3.4 billion barrels of undiscovered, technically recoverable natural gas liquids according to the new assessment.

USGS Methodology for Assessing Continuous Petroleum Resources

USGS Publication: Open-File Report 2011–1167
The U.S. Geological Survey (USGS) has developed a revised quantitative methodology for assessing resources in continuous (unconventional) petroleum deposits. Continuous petroleum resources include shale gas, coalbed gas, and other oil and gas deposits in low-permeability (“tight”) reservoirs.

Oil Shale Resources of the Eocene Green River Formation, Greater Green River Basin, Wyoming, Colorado, and Utah

USGS Publication: Digital Data Series 69-DD
The U.S. Geological Survey (USGS) recently completed a comprehensive assessment of in-place oil in oil shales in the Eocene Green River in the Greater Green River Basin, Wyoming, Colorado, and Utah. This DVD includes reports, data, and an ArcGIS project describing the assessment.

Geodatabase of Wyoming statewide oil and gas drilling activity to 2010

USGS Publication: Data Series 625
The U.S. Geological Survey (USGS) compiled a geographic information system (GIS) of Wyoming statewide historical oil and gas drilling activity for the Wyoming Landscape Conservation Initiative (WLCI). This product complements the 2009 USGS publication on oil and gas development in southwestern Wyoming  by approximating, based on database attributes, the time frame of drilling activity for each well (start and stop dates).

Gas, Oil, and Water Production from Wattenberg Field in the Denver Basin, Colorado

USGS Publication: Open-File Report 2011–1175
Gas, oil, and water production data were compiled from selected wells in two tight gas reservoirs—the Codell-Niobrara interval, comprised of the Codell Sandstone Member of the Carlile Shale and the Niobrara Formation; and the Dakota J interval, comprised mostly of the Muddy (J) Sandstone of the Dakota Group; both intervals are of Cretaceous age—in the Wattenberg field in the Denver Basin of Colorado.

Constraining the Age and Magnitude of Uplift in the Northern NPRA

USGS Publication: U.S. Geological Survey Professional Paper 1784-A
A broad, post-mid-Cretaceous uplift is defined in the northern National Petroleum Reserve in Alaska (NPRA) by regional truncation of Cretaceous strata, thermal maturity patterns, and amounts of exhumation estimated from sonic logs. Apatite fission-track (AFT) analysis of samples from three wells (South Meade No. 1, Topagoruk No. 1, and Ikpikpuk No. 1) across the eastern flank of the uplift indicates Tertiary cooling followed by Quaternary heating.
