IMHO the CAPEX can be reduced because of the flow rates for T39. If FRR's plan was to flow T39 at a rate where the well could naturally recharge without any decline. Then after a few years when the pressures were similar to zones 9, 14 and 15, they comingle all the zones. The super major could flow zone 19 at a much higher rate, reducing the overall number of years production from the well, but allowing the pressures to be equalized much earlier. Remember zone 19 was 529bbls/d for a choke of 8/64", which implies over 4,000bbls/d. If the data for example suggests that after the natural decline the flow would stabilize at 1000bbls/d and it takes 12 months to drop to this level, so FRR flow it at 1000bbls/d and there's no decline (the choke would altered). The super major could flow it at 4000bbls/d and lets say it drops to the 1000bbls/d after just 4 months. Using the figures of $3.5m per well and $75/bbl, then the payback would drop from 47 days to 12 days and for 35 the next days, there's 4 times as much profit. If the FDP was 100 wells costing $350m and producing 100,000bbls/d for the first two years, then with the super major's FDP could achieve this with 50 wells for a cost of $175m.
100 wells x 1000bbls/d x 360d = 36,000,000bbls
50 wells x 1000bbls/d x 360d = 18,000,000bbls + 4 months at an extra 3000bbls/d = (3000bbls/d x4 x30d x 50 wells = 18,000,000) = 36,000,000.These figures are just for illustration, but show how for lower CAPEX, extra profit could be achieved, due to the increased flow in the early life of the well. Also, there's the extra profit from comingling earlier.
