Data Tables from World Petroleum Assessment 2000 (DDS 60)

The following files contain the supporting data for the World Petroleum Assessment and are the source for the various plots, data tables, and summary tables used in this report.

auvol.tab - Table contains 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 contains 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 contains 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, oil fields and gas fields, respectively.
frac_au.tab - Table contains 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): oil in oil fields; gas in oil fields; natural gas liquids (NGL) in oil fields; the largest undiscovered oil field; gas in gas fields; liquids in gas fields; and the largest undiscovered gas field.
gdisc.tab - Table contains 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 contains 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 contains 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 in place of volumes for which only one field is present.
master.tab - Table contains 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 contains 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 contains 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 contains summary results of the Monte Carlo calculations.  Results are reported at the assessment unit level. Each assessment unit is represented by two rows, oil fields and gas fields, respectively.
sum_ca.tab - Table contains 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 contains 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; oil fields and gas fields, respectively. 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 contains summary results of the Monte Carlo calculations. Results are reported at the Country level. Each Country is represented by two rows, oil fields and  gas fields, respectively.
sum_pa.tab - Table contains 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 contains summary results of the Monte Carlo calculations.  Results are reported at the province level. Each province is represented by two rows, oil fields and gas fields, respectively.
sum_pt.tab - Table contains 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; oil fields and gas fields, respectively. 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 contains summary results of the Monte Carlo calculations.  Results are reported at the region level. Each region is represented by two rows, oil fields and gas fields, respectively.
sum_tps.tab - Table contains 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, oil fields and gas fields, respectively.
tpsvol.tab - Table contains 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.

Monte Carlo Simulation programs - from Chapter MC, World Petroleum Assessment 2000 (DDS 60)
 

EMCEE and Emc2 are Monte-Carlo simulation programs for assessing undiscovered conventional oil and gas resources. EMCEE allows a variety of distribution types for input, while Emc2 works with a specific set of distributions. They run as spreadsheet workbooks in Microsoft Excel. EMCEE and Emc2 require Crystal Ball, a Monte Carlo simulation program from Decisioneering, Inc. that runs in Microsoft Excel.  For futher information, refer to Chapter MC of DDS60.

World Geologic Maps

In support of the 2000 World Petroleum Assessment (DDS60), a series of geologic maps were captured, resulting in near global coverage of coarse resolution surface geology.  Each of these maps were published as Open-File Reports on CD but are available for use in a variety of formats.
