The Troll question

Yesterday's GBA (but not the interruptions) was caused by a problem with the Troll field. Norway face a number of challenges as to what to do with gas. One thing they can do is to reinject it into other fields to maintain pressure for oil extraction. Alternatively it can be piped elsewhere.

The following is a rather badly formatted chart of the flows from the Langeled pipeline in 2010. The National Grid website will do nice charts, but it is a very unreliable website that often crashes. Hence I have had to do this from the data instead.


Note the variability. Remember that 70 mcm/d is a large proportion of the 450 or so that we are using. The variability is what causes problems in the UK.
