INSTRUCTIONS FOR THE USE OF CASH.xls SPREADSHEET

TO GENERATE CASHFLOW TABLE

    1      Choose CASHFLOW SET UP from the Tools menu
    2      Select the parameters you wish to update, by checking the appropriate box
    3      As long as the GENERATE CASHFLOW TABLE box is checked, the results will be calculated

Note:      There is a slight variation in the NPVs of the Plant Access cases (when compared to Table 4 in the report
           "Economics of Gas Gathering and Processing in the Cooper Basin" as the Royalty calculation formula required updating
           See Results Sheet

BACKGROUND

This spreadsheet contains all the economic data which froms the basis for the MESA report "Economics of Gas Gathering
and Processing in the Cooper Basin".

Economic data from the following GPA Engineering reports have been input:

           Cooper Basin Gas Field Development Study - updated version, March 1996
           Moomba and Port Bonython Replacement Study - January 1996

(These reports form appendices to the MESA report).
These data are used to automatically generate a cashflow table, based on information selected in the INPUT page.

The economic data is input as individual components as follows:

NOTES:
1.         NPV at 12.5% real discount rate
2.         Gas Price at head of pipeline = $2.00/GJ, LPG price delivered to Adelaide = $335/tonne,
           Condensate price at Adelaide Refinery = $157/m3 ($25/bbl).
3.         Gas field is 50 km from Moomba and 20 km from the nearest satellite.
4.         For "Stand-Alone - LPG Recovered Case", condensate and LPG is tolled through the Liquids Pipeline
           and Port Bonython at $70/m3 ($11.10/bbl).
5.         (*) indicates estimate based on "LPG NOT Recovered" case.
6.         (**) indicates estimate based on "low CO2, low liquids" case.
7.         For multiple field cases, individual field OGIP is 10 bcf each.
8.         For multiple field cases with lean composition, economic original-gas-in-place > 20 bcf for 10% discount rate

NOTES:
1.         NPV at 12.5% real discount rate
2.         Gas Price at head of pipeline = $2.00/GJ, LPG price delivered to Adelaide = $335/tonne,
           Condensate price at Adelaide Refinery = $157/m3 ($25/bbl).
3.         Gas field is 50 km from Moomba and 20 km from the nearest satellite.
4.         For "Stand-Alone - LPG Recovered Case", condensate and LPG is tolled through the Liquids Pipeline
           and Port Bonython at $70/m3 ($11.10/bbl).
5.         Use recovery factor from nearest profitable case (generally 50 bcf case)
6.         (*) indicates estimate based on "LPG NOT Recovered" case.
7.         (**) indicates estimate based on "low CO2, low liquids" case.
8.         For multiple field cases, individual field OGIP is 10 bcf each.
9.         For multiple field cases with lean composition, economic recoverable raw gas >15 bcf for 10% discount rate
