Play Gas Discovery History Table

 

Table Name:Play Discovery History Table for Gas- PLGDSC##, where ## = Province number.
Table Function:This Province-level table contains the Play-level binned distribution of discovered sizes of gas, divided by the stage of the exploration cycle (i.e. 1/3rd or 1/2rd).
USGS Input Tables:hist#.tab,tsp#.tab and conv#in.tab (where # = Region number).
  1. Play Number [play_num] - the play number. [from hist#.tab]
  2. Play Name - the play name. [from conv#in.tab]
  3. Play Discovery Sequence [acc_disc_seq] - the portion of the discovery sequence (for example, the first third or the second half, as calculated by number of accumulations) or the total for that commodity. [from hist#.tab]
  4. Play Disc. Sequence Date [date] - the date (year) of the end of that portion of the discovery sequence. [from tsp#.tab]
  5. Play Disc. Sequence Volume [total_vol] - the total volume of resource of the commodity discovered during that portion of the discovery sequence (in thousands of barrels of oil). [from tsp#.tab]
  6. Play Disc. Sequence Size Mean [size_mean] - the mean size of accumulations discovered during that portion of the discovery sequence sequence (in millions of cubic feet of non-associated gas). [from tsp#.tab]
  7. Play Disc. Sequence Size Median [size_median] - the median size of accumulations discovered during that portion of the discovery sequence sequence (in millions of cubic feet of non-associated gas). [from tsp#.tab]
  8. Play Disc. Sequence Size Maximum [size_max] - the maximum size of accumulations discovered during that portion of the discovery sequence sequence (in millions of cubic feet of non-associated gas). [from tsp#.tab]
  9. Play Disc. Sequence Accumulations [num_accums] - the number of accumulations discovered during that portion of the discovery sequence. [from tsp#.tab]
  10. Play Disc. Sequence Shape [shape_factor] - the shape factor for the truncated shifted Pareto (TSP) distribution fit to the size data for accumulations discovered during that portion of the discovery sequence (See Houghton and others, 1993.) [from tsp#.tab]
  11. Play Disc. Sequence Fractile 95 [F95] - 95% fractile for the TSP distribution of accumulations discovered during that portion of the discovery sequence. For example 95% means that 95% of the accumulations are larger than the listed amount of resource sequence (in millions of cubic feet of non-associated gas). [from tsp#.tab]
  12. Play Disc. Sequence Fractile 50 [F50] - 50% fractile for the TSP distribution of accumulations discovered during that portion of the discovery sequence. For example 50% means that 50% of the accumulations are larger than the listed amount of resource sequence (in millions of cubic feet of non-associated gas). [from tsp#.tab]
  13. Play Disc. Sequence Fractile 05 [F05] - 5% fractile for the TSP distribution of accumulations discovered during that portion of the discovery sequence. For example 5% means that 5% of the accumulations are larger than the listed amount of resource sequence (in millions of cubic feet of non-associated gas). [from tsp#.tab]
  14. Bin 9 [bin_1] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 6 to 12 BCFG. [from hist#.tab]
  15. Bin 18 [bin_2] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 12 to 24 BCFG. [from hist#.tab]
  16. Bin 36 [bin_3] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 24 to 48 BCFG. [from hist#.tab]
  17. Bin 72 [bin_4] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 48 to 96 BCFG. [from hist#.tab]
  18. Bin 144 [bin_5] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 96 to 192 BCFG. [from hist#.tab]
  19. Bin 288 [bin_6] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 192 to 384 BCFG. [from hist#.tab]
  20. Bin 576 [bin_7] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 384 to 768 BCFG. [from hist#.tab]
  21. Bin 1152 [bin_8] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 768 to 1536 BCFG. [from hist#.tab]
  22. Bin 2304 [bin_9] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 1536 to 3072 BCFG. [from hist#.tab]
  23. Bin 4608 [bin_10] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) from 3072 to 6144 BCFG. [from hist#.tab]
  24. Bins >6144 [bin_11-bin_15] - the number of discovered accumulations in the play with estimated ultimate recovery (ungrown) greater than 6144 BCFG [from hist#.tab]
