Areas where geologic conditions are more favorable for current underground mining technology in the Kaiparowits Plateau study area, southern Utah (kaisumg )
Published By U.S. Geological Survey, Department of the Interior
Issued about 9 years ago
Summary
Description
This is a coverage that shows areas in the Kaiparowits Plateau where geologic conditions in the Calico and A-sequences are more favorable for current underground mining technology (Hettinger and other, chap. T). This coverage contains numerous attributes of information. It was compiled by computing the geometric intersection of nine polygon coverages using the ARC/INFO UNION command. This coverage is characterized as being a GUIDE TO WHERE THE MORE FAVORABLE COAL AREAS ARE LIKELY TO BE for current underground mining technology: areas where coal beds in the Calico and A-sequences are greater than 3.5 feet thick, less than 3,000 feet deep, and inclined by less than 12 degrees, as described in Hettinger and others, 1999. Additional work is required to determine the mineability and economics of these coal deposits. The outside polygon defines the base of the coal-bearing Calico and A-sequences of the Straight Cliffs Formation east of 112 degrees of longitude. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age. This polygon includes areas where the coal-bearing Calico and A-sequences have been partially eroded.

Description
The structure contours were created using biostratigraphic data in the Paleo-Data, Inc., Tenroc Regional Geologic Database. The depths of the microfossil locations were associated with the wells data provided by the Louisiana Department of Natural Resources. Because of the proprietary nature of the Tenroc database, no actual data can be shown and only those data points contained in the Louisiana State wells database are included in the control points layer. Contouring was accomplished in Dynamic Graphics, Inc., EarthVision modeling software (v.5) using minimum tension gridding. Three custom programs were used to convert contour lines generated from grids in EarthVision to Arc/Info coverages and then to shapefiles. The data are provided as both lines and polygons (lm1toplg.shp and lm1toppg.shp), and the public wells that penetrate the top of the Lower Miocene 1 (LM1) sequence are provided in a point shapefile (lm1topptg.shp). These datasets contain basic data and interpretations developed and compiled by the U.S. Geological Survey's Framework Studies and Assessment of the Gulf Coast Project. Other major sources of data include publicly available information from state agencies as well as publications of the U.S. Geological Survey and other scientific organizations. In cases where company proprietary data were used to produce various derivatives such as contour surfaces, the source is cited but the data are not displayed.

Summary
Description
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 geologists 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 elements that define the Assessment Unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are Assessment Units that border the Federal-State water boundary. In these cases, the Federal-State water boundary forms part of the Assessment Unit boundary.

Summary
Description
Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating 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 are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell 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 solution to overcome the problem of displaying proprietary PI/Dwights PLUS Well Data. No proprietary data are displayed or included in the cell maps. The data from PI/Dwights PLUS Well Data were current as of April 2003 when the cell maps were created in 2003.

The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The Hanna, Laramie, Shirley Basins Province is located in south-central Wyoming and north-central Colorado, encompassing all or parts of Larimer County in Colorado and all or parts of Albany, Carbon, Converse, and Natrona, Counties in Wyoming. The main population centers within the study area are Laramie and Rawlins Wyoming. The main highways are I-80, which traverses the area east to west and U.S. Highway 287, which generally traverses the area from north to south. The North Platte, Medicine Bow, and Laramie rivers and their tributaries drain the area. The province boundary was drawn to include the geologic structures generally considered to be in the Hanna, Laramie, and Shirley Basins.

This dataset (located by latitude and longitude) is a subset of the geochemical dataset found in Chap. H, Appendix 2, Disc 1, and used in this study of the Pocahontas No. 3 coal bed. That dataset is a compilation of data from the U.S. Geological Survey's (USGS) National Coal Resources Data System (NCRDS) USCHEM (U.S. geoCHEMical), The Pennsylvania State University (PSU), and the West Virginia Economic and Geological Survey (WVGES) coal quality databases. The metadata file for the complete dataset is found in Chap. H, Appendix 3, Disc 1 (please see it for more detailed information on this geochemical dataset). This subset of the geochemical data for the Pocahontas No. 3 coal bed includes ash yield, sulfur content, SO2 value, gross calorific value, arsenic content and mercury content for these records, as well as the ranking of these values, which is described later under the attributes in this metadata file. Analytical techniques are described in the references in Chap. H, Appendix 4, Disc 1. The analytical data are stored as text fields because many of the parameters contain letter qualifiers appearing after the numerical data values. The following is a list of the possible qualifier values: L - less than, G - greater than, N - not detected, or H - interference that cannot be easily resolved. Not all of these codes may be in this database.

Summary
Description
This shapefile includes polygons and regions that describe U.S. Geological Survey defined petroleum resource Assessment Units of northern Afghanistan. Each assessment unit is defined as a mapable volume of rock within a total petroleum system that encompasses fields (discovered and undiscovered) that share similar geologic traits and socio-economic factors. The fields inside an assessment are a sufficiently homogenous population that a single methodology of resource assessment is applicable. Assessment units are described by U.S. Geological Survey research scientists on the basis of available geologic knowledge, exploration and production histories, and extensive literature searches. Assessment units are identified with a numeric code derived from the numeric code of the World Geologic Provinces defined by the U.S. Geological Survey World Petroleum Assessment 2000.

Summary
Description
A geographic information system focusing on Tertiary strata and Cretaceous-Tertiary coalbed gas was developed for the U.S. Geological Survey's (USGS) 2007 assessment of undiscovered, technically recoverable oil and natural gas resources of the Gulf Coast Region. The USGS Energy Resources Science Center has developed map and metadata services to deliver the 2007 assessment results GIS data and services online. The Gulf Coast assessment is based on geologic elements of a total petroleum system (TPS) as described in Dubiel and others (2007) and Warwick and others (2007). The estimates of undiscovered conventional oil and gas resources are within 33 assessment units (AUs) and the estimates of continuous coalbed gas resources are within 4 AUs. The hydrocarbon assessment units include the assessment results as attributes within the AU polygon feature class (in geodatabase and shapefile format). Quarter-mile cells of the land surface that include single or multiple wells were created by the USGS to illustrate the degree of exploration and the type and distribution of production for each assessment unit. Other data that are available in the map documents and services include the TPS and USGS province boundaries, as well as Claiborne Group structure and isopach maps.
