auvol.tab - Table containing volumetric data of discovered petroleum in regions, provinces, total petroleum systems, and assessment units. These volumes are the sum of volumes of individual fields reported in Petroconsultants (1996) and NRG Associates (1995).

 

bin_au.tab - Table containing the field size distribution of undiscovered fields.  Results are divided into binned field-size classes and reported at the assessment unit level. The class limits are in millions of barrels of oil equivalent (MMBOE), where 6000 cubic feet of gas equals one equivalent barrel. Each assessment unit is represented by two rows, one for oil fields and one for gas fields.
bin_prov.tab - Table containing the distribution of field sizes of undiscovered fields.  Results are divided into binned field-size classes and reported at the province level. The class limits are in millions of barrels of oil equivalent (MMBOE), where 6000 cubic feet of gas equals one equivalent barrel. Each province is represented by two rows, one for oil fields and one for gas fields.
frac_au.tab - Table containing fractiles from the results of the Monte Carlo calculations.  Results are reported at the assessment unit level. Each assessment unit is represented by seven rows (distinguished by the values of columns 3 and 4): one for oil in oil fields, one for gas in oil fields, one for natural gas liquids (NGL) in oil fields, one for the largest undiscovered oil field, one for gas in gas fields, one for liquids in gas fields, and one for the largest undiscovered gas field.
gdisc.tab - Table containing information regarding known and grown volumes of petroleum in an assessment unit. Grown field sizes are defined as known field sizes that were adjusted upward to account for estimated future reserve growth. These tables contain 54 columns. NA means not applicable and shown either in place of volumes for which only one field is present.
input.tab - Table containing input data from the Seventh Approximation World Petroleum Assessment Data Forms for Conventional Assessment Units used in this report. For some Canadian assessment units, pool data, rather than field data, are reported. Blank cells represent no data. This table contains 147 columns.
kdisc.tab - Table containing information regarding known and grown volumes of petroleum in an assessment unit. Grown field sizes are defined as known field sizes that were adjusted upward to account for estimated future reserve growth. These tables contain 54 columns. NA means not applicable and shown either in place of volumes for which only one field is present.
master.tab - Table containing names and codes of the hierarchical structure of assessment units that were identified in World Petroleum Assessment 2000. The hierarchical structure includes USGS-regions, provinces, total petroleum systems, and assessment units. 
provvol.tab - Table of volumetric data of discovered petroleum in regions, provinces, total petroleum systems, and assessment units. These volumes are the sum of volumes of individual fields reported in Petroconsultants (1996) and NRG Associates (1995). These tables contains 31 columns. NA means not applicable and is shown either in place of discovered volumes for which only one field is present, or for undiscovered volumes and values calculated from these volumes in assessment units not quantitatively assessed.
regvol.tab - Table containing volumetric data of discovered petroleum in regions, provinces, total petroleum systems, and assessment units. These volumes are the sum of volumes of individual fields reported in Petroconsultants (1996) and NRG Associates (1995) database. These tables contains 31 columns. NA means not applicable and is shown either in place of discovered volumes for which only one field is present, or for undiscovered volumes and values calculated from these volumes in assessment units not quantitatively assessed.
sum_au.tab - Table containing summary results of the Monte Carlo calculations.  Results are reported at the assessment unit level. Each assessment unit is represented by two rows, one for oil fields and one for gas fields.
sum_ca.tab - Table containing the Country allocation summary results from the Monte Carlo calculations.  Results are reported at the parcel level. Each parcel is identified by the assessment unit being allocated (columns 3 and 4), the country to which the allocation is made (column 1), the onshore or offshore identification (column 2), and the field type (column 5).
sum_ct.tab - Table containing country allocation totals from the summary results of the Monte Carlo calculations.  Results are reported at the parcel level. Each parcel is identified by the country to which the allocation is made (column 1), the summation level (column 4), and the field type (column 5). The three summation levels are onshore total, offshore total, and (grand) total. For each summation level, there are two rows; one for oil fields and one for gas fields. The structure of the country summary totals table, sum_ct.tab, is the same as the country summary allocation table, sum_ca.tab, so that these files can be appended if desired. The only columns treated differently are columns 2, 3, and 4.
sum_ctry.tab - Table containing summary results of the Monte Carlo calculations. Results are reported at the country level. Each country is represented by two rows, one for oil fields and one for gas fields.
sum_pa.tab - Table containing province allocations from the summary results of the Monte Carlo calculations. Results are reported at the parcel level. Each parcel level is identified by the assessment unit being allocated (columns 4 and 5), the province to which the allocation is made (columns 1 and 2), the onshore or offshore identification (column 3), and the field type (column 6).
sum_prov.tab - Table containing summary results of the Monte Carlo calculations.  Results are reported at the province level. Each province is represented by two rows, one for oil fields and one for gas fields.
sum_pt.tab - Table containing the province allocation totals from the  summary of results of the Monte Carlo calculations.  Results are reported at the parcel level. Each parcel is identified by the province to which the allocation is made (columns 1 and 2), the summation level (column 5), and the field type (column 6). The three summation levels are onshore total, offshore total, and (grand) total. For each summation level, there are two rows; one for oil fields and one for gas fields. The structure of the province summary totals table, sum_pt.tab, is the same as the province summary allocation table, sum_pa.tab, so that these files can be appended if desired. The only columns treated differently are columns 3, 4, and 5.
sum_reg.tab - Table containing summary results of the Monte Carlo calculations.  Results are reported at the region level. Each region is represented by two rows, one for oil fields and one for gas fields.
sum_tps.tab - Table containing summary results of the Monte Carlo calculations.  Results are reported at the total petroleum system level. Each total petroleum system is represented by two rows, one for oil fields and one for gas fields.
tpsvol.tab - Table containing volumetric data of discovered petroleum in regions, provinces, total petroleum systems, and assessment units. These volumes are the sum of volumes of individual fields reported in Petroconsultants (1996) and NRG Associates (1995). These tables contains 31 columns. NA means not applicable and is shown either in place of discovered volumes for which only one field is present, or for undiscovered volumes and values calculated from these volumes in assessment units not quantitatively assessed.
