This coverage includes arcs, polygons and polygon labels that describe U.S. Geological Survey defined geologic provinces of Europe including Turkey. (Albania, Andorra, Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Liechtenstein, Luxembourg, The Former Yugoslav Republic of Macedonia, Malta, Monaco, Netherlands, Norway, Poland, Portugal, Romania, San Marino, Serbia and Montenegro, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, United Kingdom and Vatican City.) Each province has a set of geologic characteristics distinguishing it from surrounding provinces. These characteristics may include the...

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. A database was compiled that includes about 47,000 Fischer assays from 186 core holes and 240 rotary drill holes. Most of the oil yield data were analyzed by the former U.S. Bureau of Mines oil shale laboratory in Laramie, Wyoming, and some analyses were made by private laboratories. Total in-place resources for the three assessed units in the Green River Formation are: (1) Tipton Shale Member, 362,816 million barrels of oil (MMBO), (2) Wilkins Peak Member, 704,991 MMBO, and (3) LaClede Bed of the Laney Member, 377,184...

The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic...

Data are contained in a Microsoft Access database consisting of 27 data tables. Tables provided include emergency stabilization and rehabilitation (ESR) projects sampled, study plot characteristics, and sampled vegetation and fuels data. All data are from Bureau of Land Management (BLM) federal lands within the Great Basin region of the intermountain west. These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release.

This report presents the methodology used in the geology-based assessment of the in-place oil resources in 18 oil shale zones of the Eocene Green River Formation in the Uinta Basin of northeastern Utah. The focus is on the methodology used to (1) convert legacy data; (2) analyze the data through application of current computer techniques; and (3) ultimately quantify the resultant data using spreadsheet, database, and geographic information systems (GIS) software.

Monte Carlo programs described in chapter MC, Monte Carlo Simulation Method. Emc2.xls was the program used to calculate the estimates of undiscovered resources for the World Petroleum Assessment 2000. The emcee.xls program is a more generalized version of the program, with options for different distribution types. Directions for the use of both programs are fully documented in chapter MC.

A detailed description of the methodology employed to perform a geology-based assessment of in-place oil shale and nahcolite resources in the Piceance Basin of northwestern Colorado is presented here. Considerable advancements in computer and database technology since the previous oil shale assessment in 1989 provided the U.S. Geological Survey (USGS) assessment team with new tools to convert legacy data, store and manipulate new data, perform calculations, and quantify, report, and display the assessment results. Relational database and geographic information systems (GIS) software were used seamlessly to streamline the storage and manipulation of the data. A deterministic spatial interpolation method, the Radial...

Cell maps for each oil and gas assessment unit were created by the USGS to illustrate the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells were then coded to indicate whether the wells included within the cell are predominantly oil-producing, gas-producing, are both oil- and gas-producing, or are dry or the type of production is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic...

This model has been superseded by an updated version of the model. The new model can be found at: https://doi.org/10.5066/P99KJ1U1, https://doi.org/10.5066/P9FTZ5RW, https://doi.org/10.5066/P9NBWLYX, https://doi.org/10.5066/P97XBULI, https://doi.org/10.5066/P980EHWV, https://doi.org/10.5066/P95XLBB5, https://doi.org/10.5066/P9ICSZWF, https://doi.org/10.5066/P96LJ01V, and https://doi.org/10.5066/P9IZRO3V. A three-dimensional groundwater flow model (MODFLOW200-FMP1_1) of the Central Valley in California was developed to aid water managers in understanding how water moves through the aquifer system, to predict water-supply scenarios, and to address issues related to water competition.
