RE: 750bbls /d6 Oct 2018 20:09
Lordlash - Your post as a reply to my flow rate calculation implies that the calculation is crazy.
Lets look at the facts first.
Zaza stated 3 trainloads and 4 to 6 weeks to fill a trainload. Also stated in a previous podcast 1000bbls/d by the end of the year and T39 gas increasing.
FRR twitter picture shows a trainload being inspected on 25th June.
bugsy-b's post on 25th September had the link from GOGC about the two trainloads for auction on 10th September and 1st October. Each trainload contains 5000t light crude, which is 30,000bbls using the lowest conversion factor of 6 (6 - 8 is the conversion factor based upon density). Therefore, 90,000bbls for the 3 trainloads.
T45 started testing on the 8th April and had stable flows of 270bbls/d.
Dino-2 started testing on the 18th May and had stable flows of 315bbls/d.
T39 started EWT on the 4th July and unstimulated flows of 529bbls/d ( 8/64" choke) and 250bbls/d ( 6/64" choke).
Zone 9 wells have been producing around 130bbls/d resulting in 1 trainload about every six months.
Assumptions :-
154 days of oil flow to fill the 3 trains. We know that 2 trainloads were up for auction by bugsy-b's post on the 25th September, with the first ready by the 10th September. Therefore, I have assumed that both were filled by the 10th, which gives 154 days from the T45 start (but they could have still been filling the second up to the 25th).
Zone 9 wells 130bbls/d for for 154 days = 20,020bbls.
T39 still flowing at 250bbls/d as the gas is increasing, which for 68 days from 4th July = 17,000bbls.
90,000bbls - (20,020 + 17,000)bbls = 52,980bbls is required from T45 and Dino-2.
We know that if there was no decline in the flow rates of T45 and Dino-2, then T45 flowed for 40 days and both together for the remaining 114 days. This gives 270bbls/d x 40 = 10,800bbls and (270 + 315)bbls/d x 114 = 66,690bbls. Therefore, the total from T45 and Dino-2 without decline would be (10,800 + 66,690)bbls = 77,490bbls.
The difference between the figure without decline and what is required from T45 and Dino-2 can then be used to show the percentage that the flow rates have declined for the total amounts.
(77,490 - 52,980)bbls = 24,519bbls, which is a 31.63% decline.
Applying the same percentage decline to the initial flows for T45 and Dino-2 will then give the average flow for the wells. Therefore, T45 = 185bbls/d and Dino-2 = 215bbls/d. As most decline will be early in the EWT, the graphs are usually an exponential decline shape, with the average fairly close to the final flow rates. Therefore, I have assumed T45 = 170bbls/d and Dino-2 = 215bbls/d.
T45 + Dino-2 + T39 + Zone 9's = (170 + 200 + 250 + 130)bbls/d = 750bbls/d.
At 750bbls/d it would take 40 days to fill a train, which is just under 6 weeks, the upper time-frame Zaza stated. If T39's testing is complete at 6/64" choke and the choke is opened to 8/64" = 529bbls/d and the total becomes 1029bbls/d, which would fill a train in 29 days, 1 day over 4 weeks,
