Special Problem: US Oil production is often sited as an example of M. King Hubbert's model of resource use.  The US yearly petroleum production to 1995 is plotted here in billions of barrels per year. Q_T = total extractable resource, the area under the production curve for US oil was estimated to be 284 x 10⁹ bbl. The amount of oil produced up through 1995 was 171x10⁹ bbl, and the production rate in 1995 was 2.1x10⁹ bbl/year.

Using the Hubbert model, please calculate:           a.) the amount of oil remaining at the end of 1995.           b.) the value of z in 1995. where z is the distance to the peak in units of the standard deviation.           c.) the peak production rate of oil (NM).           d.) the standard deviation, sigma, of the Hubbert model.           e.) the year of peak oil production, TM, according to the model.           f.) the year when only 10% of the total extractable oil remains.
