Just another interesting geometric pattern:

On Sundays I usually write a technical post that has, in the past, covered the ways in which oil and gas have been, and are recovered. I have done the same with a series on coal. For those interested I have listed those posts in an archive for each that is given at the bottom of this column.
On Saturdays I have been reviewing the actual temperature records for the different States of the Union, looking, over the past hundred and fifteen years, both at the reports after homogenization, and the Time of Observation corrected raw data. Those reviews, with their conclusions, are given for the individual states, as I get to them, also at the bottom of this column. Check your state out.
One of the problems in following stories in different countries is that they use different units and symbols. This can be a bit confusing, and so, where I can, I will try and standardize on the unit of barrel/day, or bd for oil. I will also use a thousand cubic ft kcf for natural gas. Prices will also be standardized, when I can, in $/kcf for natural gas, $/barrel for oil, and $/gallon for gasoline.
In larger units volumes a thousand barrels a day becomes 1 kbd and a million barrels a day becomes 1 mbd. For natural gas a million cu ft per day will be 1 mcf. (In many quotes this has appeared as 1 MMcf).
A billion cu. ft. is 1,000 mcf. Note that a cubic foot of gas produces 1,030 Btus - so to simplify 1 million Btu's is approximately 1 kcf, or 28.3 cu.m. of natural gas equivalent.
A ton of oil is 7.33 barrels. (Mainly used in Eastern Europe).
Since not all posts before this show these units - note that this change happened on March 3, 2009.
