We showed a version of this graph in our November Inner Circle Monthly report which shows the two most common global benchmars, WTI and Brent and the Average Realized Oil Price in Colombia, as measured by those operators which report pricing. The Unweighted Average lies almost perfectly between average WTI and average Brent. The production-weighted Average is heavily pulled by Ecopetrol and shows more variation. The dotted lines show our estimate of these values for 4Q12 and our (admittedly early-days) projection of the numbers for 1Q12.
