PARTIE 1 RAPPEL : LA PROBLEMATIQUE DU PIC DU PETROLE 2
Brief summary of past findings and views • The only "publically available data" on oil reserves are the so called "proven reserves". • Unfortunately, they are totally useless to study and predict "Peak Oil". • The only "usable" concepts for "peak oil estimation", at oil basins levels, countries levels or world level are : • Ultimate reserves concept • Evolution of past exploration performances and production curves (creaming curves) • King Hubbert methodology (world applicability). 3

Conclusions about "peak oil" • Since June 2006 it can be considered that views about Peak Oil in France have become reasonably similar : • TOTAL : Thierry Desmarest – around 2020 / around 100 Mb/d • ASPO France : J. Laherrère – around 2015 / less than 100 Mb/d • IFP : Y. Mathieu –ondulated plateau 20150/2030 – less than 100 Mb/d • This point of view is widely different from those among the "optimists" who believe that Peak Oil is not "reserves related" but a political problem : insufficient investments and restrictive policies about investments by OPEC countries, Russia and Mexico : • Exxon-Mobil – ongoing at ad. Campaign "no signs of peak oil" • Aramco – July 2006 – "no reserves problems" • BP : John Browne – May 2006 - "There is no reserves problem" • Mike Lynch (ex MIT) – "similar and above 120 Mb/d" • USGS, DOE, EIA, IEA… 12

Moindre maturité de l'exploration gaz pour le Courbes d'écrémage. . Plus d'incertitudes pour les ressources en place non conventionnelles de gaz que de pétrole ? Etudes "bottom-up" : . Méthodologie la plus prometteuse. Courbes de Hubbert : . L'échec aux USA . L'applicabilité probable au plan mondial. 15

Conclusions • Il reste beaucoup de travail à faire pour mieux déterminer les deux paramètres essentiels du "pic gaz" au plan mondial : • Date ou fourchette de dates • Niveau de production mondiale. • L'IFP; l'AFGTP, l'AFG… et l'ASPO doivent y consacrer des efforts importants car les enjeux sont majeurs : ce devrait être un pôle privilégié de coopération entre l'AFG et l'AFTP. • Il faut que ces travaux soient consacrés tant aux études globales ("Top Down") que détaillées ("Bottom Up"). (objectif PRB 2007 : un profil gaz mondial long terme "Bottom Up") 24
