I've been trying to estimate what the situation is going to be like in 2010.
However working out who to believe is giving the most accurate figure for natural gas depletion rates is annoying. The EIA website quotes the DTI as saying that in 2003 the UK produced 4 tcf. However the BP report for 2003 says that gas production was at 10 bcf/d. Obviously this makes a total of 3.65 tcf for the year. This is why the BP report says that natural gas depletion was only 6.7% last year. Compare this to the reports that say the decline was 13% last year and this begins to look really annoying.
But it's all part of depletion modelling I guess.
Anyway I used a depletion rate of 11% and came to a figure of just under 2 tcf for 2010. Though I feel this to be slightly optimistic.
If consumption rates grow at the same rate then consumption will be around 3.6 tcf/y.
Overall I estimate a shortfall of between 1.8-2.2 tcf/y by the year 2010.
Anyone else have any figures. Maybe I'm being too optimistic/pessimistic.
