Continuous spot prices have to be paid for.

As you can see fron the index the price rose from GBP 2.788/Million BTU ($5.04)on June 29 2005 to peak at GBP 10.843/Million BTU ($18.76)on December 3 2005 and has now fallen back to GBP 8.292/Million ($14.59)

Using 1,027,000 BTUs per 1000 cf, we get $14.98/1000 cf basically the same as where it was in the US two weeks ago. On Dec 3rd it looks like it hit about $19.50. When you convert these BTU's to oil equivalent you're still looking at only about $90. Well within reason.

But don't quote me on those numbers. Isaiah will be all over my case.
