Tux, there is no real difference in reporting.The contingent resource was not expressed in BOE, rather 26MB of oil and 22 BCF of gas. The new figure appears to represent a combined total of oil and gas as boe. This seems a little light as the norm is to divide BCF by 3 for energy equivalent, ie 26 + 22/3 or 33.3MBOE. It would seem they have also adjusted for lower gas values.
