why do you have x6 for the number of days worked a week and then 24 for the number of days worked in the month still?
In a month there are about 26 working days (though Saturdays are half days) which is what I actually used in my calculation (not 24 which was a simple 4 weeks x 6 days).
Your calculation has 144 working days per month (6 x 24)! The table also says there are 16 2 way trips initially - this also more or less agrees with the initial 500 tonnes of oil which is approx. 16 loaded tankers.
The reason to use the average of the start number of tankers of consecutive periods is because the decline will be continuous not in steps - for example first period of 4 months there's a maximum 16 tankers (presumably at the start) and second period 12 maximum so (simplistically) after 2 months there would be 14 tankers and just before the second period it should be 12 tankers. This would give an average of about 14 tankers a day throughout the first period.
As I also pointed out if your answer of total production is significantly different from volume of oil that would be exported by the number of tankers that is in the RNS (3 a day average over 20 years) then there's something wrong with your calculation.
So working days a year about 305, number of years 20 = 6,100 days. 3 tankers a day = 18,300 tankers
Volume of oil in each tanker 214 barrels = so 214 x 18,300 = 3,916,200bbls
I would wait for a CPR with a 'proper' economic run as there are many factors that would affect the future value of the oil, not only the OP but inflation, exchange rate as oil is in USD and of course when the oil is produced. The OPEX per barrel will also rise as production declines, and OPEX isn't the only cost attributable against the site.
