The assessment unit is the fundamental unit used in the National and Global Oil and Gas 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 herein 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 elements that define the assessment unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies. Machine-readable tables are provided that contain the input and results for each assessment unit summarized in the U.S. Geological Survey (USGS) Fact Sheet. Methodology of assessments are documented in USGS Data Series 547 for continuous assessments (https://pubs.usgs.gov/ds/547) and USGS DDS69-D, Chapter 21 for conventional assessments (https://pubs.usgs.gov/dds/dds-069/dds-069-d/REPORTS/69_D_CH_21.pdf). See supplemental information for a detailed list of files included this data release. The purpose of these files is to define and illustrate the geographic limit and geologic boundaries of the assessment units within the defined total petroleum systems, as required for the USGS National and Global Oil and Gas Assessment Project. This release also contains assessment input data and fact sheet data tables.

The first digit of the code indicates the World region number (5), the following three digits (5208) are the province number, the next two digits (520801) are the total petroleum system number, and the last two digits (52080101) are the assessment unit number. For more detailed assessment results data, refer to the Digital Data Series (DDS) 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 World Oil and Gas Resource Assessment website - https://www.usgs.gov/centers/central-energy-resources-science-center/science/world-oil-and-gas-resource-assessments The assessment unit boundary was based on the surface and subsurface geology of the petroleum system elements, as well as 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 total petroleum system review meeting. The assessment unit was mapped in part on the data contained in the IHSMarkit data base for wells and fields. 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 geologist and the boundary line digitally transferred using ArcGIS. The province geologist mapped the assessment unit boundary on a hard copy or digital base map that contained data from IHSMarkit data base for wells and fields. The province geologist 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 digital base map using ArcGIS. 2023 The attributes were added from the assessment output data file. These assessment results attributes are published on the National and Global Petroleum Assessment Project Fact Sheet for each Province. 2023 Identification information supplies the data necessary for record keeping and assessment organization. Statistical combination of the input parameters yields probability distributions for quantities of petroleum having the potential to be added to reserves. Selected ancillary data provide a set of information (not used directly in assessment calculations) that may be used for economic and environmental analyses. A Resource Assessment Meeting is a formal meeting of the entire National and Global Oil and Gas Assessment Project (NAGA) team to review the resource model inputs. Once the input parameters are finalized, a Monte Carlo simulation is used to produce probability distributions of results. 2023 Vector GT-polygon composed of rings 5 0.0196131152 0.0544286262 Decimal seconds WGS_1984 WGS_84 6378137.0 298.257223563 au"assessunitnum and abbreviated name" Polygon Attribute Table.
