1 - Data based on the SPE (Society of Petroleum Engineers) criterion for estimating reserves, wich was implemented from 1998 onwards.
2 - "For years prior to 1998, a conversion rule was used, in line with the reserves classification method formerly adopted by Petrobras. The code used previously placed greater emphasis on volume (the certainty of the existence of volumes) rather than economic (certainty of the economic viability of the reserve) aspects, with greater detail in the classification of volume of proven reserves.
3 - The values shown by Petrobras relate only to its interest in the concessions, that is the volume of the reserves corresponding to the percentage participation contractually established together with the other partners in a given production concession.
4 - From 2015, with the change of regulation of ANP, includes the volumes of oil and gas Shale in synthetic volumes of national reserve.
