Description:
Abstract:
This report presents a digital map of tight-gas resource assessments in the United States as part of the U.S. Geological Survey's (USGS) National Assessment of Oil and Gas Project. Using a geology-based assessment methodology, the USGS quantitatively estimated potential volumes of undiscovered, technically recoverable natural gas resources within tight-gas assessment units (AUs). This is the second digital map product in a series of USGS unconventional oil and gas resource maps. The map plate included in this report can be printed in hardcopy form or downloaded in a Geographic Information System (GIS) data package, including an ArcGIS ArcMap document (.mxd), geodatabase (.gdb), and published map file (.pmf). In addition, the publication access table contains hyperlinks to current USGS tight-gas assessment publications and web pages. Comprehensive geologic studies, supporting data, and reports on the methodology used in assessing undiscovered oil and gas resources in the United States are available at the USGS Central Energy Resources Science Center website: <http://energy.usgs.gov/OilGas/AssessmentsData/NationalOilGasAssessment.aspx>. Project Chief: Christopher J. Schenk
Purpose:
The assessment unit (AU) is the fundamental unit used in the National Assessment of Oil and Gas Project for the estimation of undiscovered oil and gas resources. The AU is defined within the context of the higher-level Total Petroleum System. The AU 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 AU boundary is defined geologically as the limits of reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are AUs that border international boundaries with Canada and Mexico, or the Federal-State water boundary. In these cases, the international boundary or the Federal-State water boundary forms part of the assessment unit boundary.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
One attribute for the assessment unit coverage is the eight digit number that identifies the USGS-specific assessment unit. The first digit of the code indicates the World region number (5), the following three digits (5067) are the North America province number, the next two digits (506703) are the Total Petroleum System number, and the last two digits (50670364) are the assessment unit number. The assessment results attributes include estimated volumes of undiscovered, technically recoverable gas and natural gas liquids. For more detailed assessment results data, refer to the CD_ROM publications for the Provinces that are available at <https://pubs.usgs.gov/dds/dds-069/> or the USGS Fact Sheets that are available for each Province at the National Oil and Gas Assessment website - <http://energy.usgs.gov/OilGas/AssessmentsData/NationalOilGasAssessment.aspx>.
Logical_Consistency_Report:
The assessment unit boundary was defined on the basis of the surface and subsurface geology of the petroleum system elements, and oil and gas production, shows, and seeps related to the assessment unit. The province geologist was required to defend the geologic boundaries of each assessment unit in a formal geologic and petroleum system review meeting.
Completeness_Report:
The assessment unit was mapped in part on the data contained in the IHS Energy Group, WHCS data base for wells, and the Nehring Significant Oil and Gas Field File.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The assessment unit boundary represents the gross boundary of the combined geologic elements that comprise the Total Petroleum System. The assessment unit boundary was mapped by the province geologists and the boundary line digitally transferred using ArcGIS.

Process_Description:
The province geologists mapped assessment unit boundaries on hard copy or digital base maps that contained data from IHS Energy Group (<http://www.ihs.com/index.aspx>), WHCS data base for wells, and the Nehring Significant Oil and Gas Field File (<http://www.nehringdatabase.com/>). The province geologists then plotted all other available geologic, geophysical and geochemical data and information on the base map to assist in mapping the assessment unit boundary. Following review, the assessment unit boundary was digitally captured from the hard copy or digitial base map using ArcGIS.
Process_Date: 2000 to 2013
Process_Step:
Process_Description:
The attributes were added from the assessment output data file. These assessment results attributes are published on the National Assessment of Oil and Gas Fact Sheet for each province.
