Title: 1995 National Oil and Gas Assessment Province Boundaries
Abstract:
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, hydrocarbon plays were defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The province boundaries were drawn on the county lines that most closely followed the natural geologic boundaries.
Supplemental_Information:
Oil and gas provinces are listed here by number, with their geographic extent and name:

  2. How were the data generated, processed, and modified?

    Date: Apr-2001 (process 1 of 1)
    We ran lins2cov.aml on the .lin files (from USGS DDS-35) to create the province coverages. The lins2cov.aml takes files from the NOGA 95 Spatial Data Disk (DDS-35), and reformats into Arc/Info Generate format (ASCII) files. They are then imported into ArcInfo coverages using the GENERATE command, subsequently they are cleaned to remove any potential overlap of polygons (using .000001 weed and fuzzy tolerances). Region/province numbers and names are appended to the file using lookup information acquired from tables on the NOGA 95 Tabular Information Disk (DDS-36). The individual province coverages were brought into Arcview where they were converted to shapefiles and were also merged to create one national shapefile.

    Data sources used in this process:

    • USGS DDS-30, Release 2
    • USGS DDS-35
    • USGS DDS-36

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    The oil and gas resources of the United States were evaluated on the basis of interpretation of the geology of its petroleum provinces. The United States was divided into eight regions, which encompass 71 provinces.

  5. How consistent are the relationships among the observations, including topology?

    Province boundaries match U.S. Census Bureau 1990 TIGER 100,000-scale county boundaries.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
