In the Phuong Dong gas condensate field, Cuu Long Basin, Vietnam, hydrocarbon inclusions in quartz trapped a variety of petroleum fluids in the gas zone. Based on the attributes of the oil inclusion assemblages (fluorescence colour of the oil, bubble size, presence of bitumen), the presence of a palaeo-oil column is inferred prior to migration of gas into the reservoir. When a palaeo-oil column is displaced by gas, a residual volume fraction of oil remains in pores....

USGS Publication: Fact Sheet 2014-3063
The powder x-ray diffraction (XRD) laboratory is managed jointly by the Eastern Mineral and Environmental Resources and Eastern Energy Resources Science Centers. Laboratory scientists collaborate on a wide variety of research problems involving other U.S. Geological Survey (USGS) science centers and government agencies, universities, and industry. Capabilities include identification and quantification of crystalline and amorphous phases, and crystallographic and atomic structure analysis for a wide variety of sample media...

USGS Publication: Open-File Report 2012–1151
The Organic Petrology Laboratory (OPL) of the U.S. Geological Survey (USGS) Eastern Energy Resources Science Center in Reston, Virginia, contains several thousand processed coal sample materials that were loosely organized in laboratory drawers for the past several decades.

USGS Publication: Open-File Report 2012–1126This report releases 234U/238U isotope data, expressed as activity ratios, and uranium concentration data from analyses completed at Northern Arizona University for groundwater and solid-phase leachate samples that were collected in and around Tuba City Open Dump, Tuba City, Arizona, in 2008.

Outside Publication: International Journal of Coal GeologyElectron beam microanalysis of coal samples in U.S. Geological Survey labs confirms that arsenic is the most abundant minor constituent in iron disulfides in coal and that selenium, nickel, and other minor constituents are present less commonly and at lower concentrations than those for arsenic.

Shale oils generated using different laboratory pyrolysis methods have been studied using standard oil characterization methods as well as Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) with electrospray ionization (ESI) and atmospheric photoionization (APPI) to assess differences in molecular composition.

USGS Publication: Data Series 635The principal mission of the U.S. Geological Survey (USGS) Energy Resources Program (ERP) is to (1) understand the processes critical to the formation, accumulation, occurrence, and alteration of geologically based energy resources; (2) conduct scientifically robust assessments of those resources; and (3) study the impacts of energy resource occurrence and (or) their production and use on both the environment and human health.

USGS Publication: Open-File Report 2011–1187Geochemistry is a constantly expanding science. More and more, scientists are employing geochemical tools to help answer questions about the Earth and earth system processes. Scientists may assume that the responsibility of examining and assessing the quality of the geochemical data they generate is not theirs but rather that of the analytical laboratories to which their samples have been submitted.
The Geochemistry Laboratory supports Energy Program needs for the inorganic and organic analysis and maintains a laboratory information system (LIMS) for geochemical data tracking and sample storage. The lab provides geochemical expertise and analytical support to Federal, State and County agencies, universities and foreign research organizations. The laboratory is located in Building 20 of the Denver Federal Center in Lakewood, CO, and is administered by the Central Energy Science Center, Energy Resources Program.
The laboratories methodologies and instrumentation focus on coal and petroleum systems geochemistry as applied to national and global energy resource assessment projects, geologic framework, and petroleum processes studies. The geochemistry lab project supports petroleum processes research project, geochemistry of solid fuels, coal research assessment methodology project, and fossil fuel environmental issues including the evaluation of natural sources of greenhouse gases, prediction and monitoring of fossil-fuel quality and baseline studies of fossil fuel in the environment. The laboratories are on the cutting edge of new methodology and method development to achieve these goals. The labs also have a large focus on data preservation and data management. A proactive approach to data management will assure data quality and accuracy for the future.

The Energy Geochemistry Laboratory (EGL) implements a Quality Management System that emphasizes a continuous commitment to improve quality and efficiency. Quality Assurance is an integral part of routine laboratory analysis and the EGL has a system in place to identify problems and prevent their recurrence. The Energy Geochemistry Laboratory Quality Management System is implemented in the QA Manual, which is written to embody the USGS Fundamental Science Practices.
Two significant data quality issues were identified in the Inorganic Section of the Energy Geochemistry Laboratory. Further information is available at the links below.
