Description:

Abstract:

The fundamental geologic unit used in the 1995 National Oil and Gas Assessment was the play, which is defined as a set of known or postulated oil and or gas accumulations sharing similar geologic, geographic, and temporal properties, such as source rock, migration pathways, timing, trapping mechanism, and hydrocarbon type. The geographic limit of each play was defined and mapped by the geologist responsible for each province. The play boundaries were defined geologically as the limits of the geologic elements that define the play, such as the limits of the reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are plays that border the Federal-State water boundary. In these cases, the Federal-State water boundary forms part of the play boundary. The play boundaries were defined in the period 1993-1994.

Purpose:

The purpose of these files is to illustrate the geologic boundary of the play as defined for the 1995 U.S. National Assessment. The play was used as the fundamental assessment unit.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The main attribute for the play in this coverage is the play number, in which the first two digits represent the province number, and the next two digits represent the play number. Other attributes include the play name, and the region and province names and numbers. Also included are the output fractiles for the distribution of volume of undiscovered resource for the conventional plays (in millions of barrels of oil, billions of cubic feet of gas, or millions of barrels of natural gas liquids). Only accumulations greater than or equal to 1 million barrels of oil or 6 billion cubic feet of natural gas are included in this part of the assessment.

Logical_Consistency_Report:

The play boundaries were defined on the basis of the surface and subsurface geology of the play, and the oil and gas production within the play. The province geologist was required to defend the geologic boundary of the play in a formal play review meeting.

Completeness_Report:

The play was mapped in part on the data contained in the PI WHCS database for wells (1990 update), and the Nehring Significant Oil and Gas Field File (1992 update). Plays with insufficient data or that were given low probability of containing an accumulation of minimum size, were not quantitatively assessed during the 1995 National Oil and Gas Assessment. Plays that were not quantitatively assessed contain only the attributes defining region/province/play names and numbers.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: The play boundary was meant to delineate the gross boundary of the geologic elements that define the play.

digital tabular data in support of the 1995 U.S. National Oil and Gas Assessment

Process_Step:

Process_Description:: We ran lins2cov.aml on the .lin files (from USGS DDS-35) to create the play 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/play numbers and names and the fractile estimates from the assessment of conventional undiscovered accumulations are appended to the file using lookup information acquired from tables on the NOGA 95 Tabular Information Disk (DDS-36). Plays with insufficient data or that were given low probability of containing an accumulation of minimum size, were not quantitatively assessed during the 1995 National Oil and Gas Assessment. Plays that were not quantitatively assessed contain only the attributes defining region/province/play names and numbers. The coverage is then converted to a shape file.
