This is a guest post by Sadad al-Huseini, now a petroleum consultant and formerly executive vice president of Saudi Aramco for exploration and production, and is a response to the recent article in PIW (Petroleum Intelligence Weekly) by Leonardo Maugeri on his new study Oil: the Next Revolution, challenging his optimism about future oil supplies (PIW Jul.2’12). This article originally appeared in the July 23, 2012 edition of PIW.

Leonardo Maugeri’s recent paper Oil: The Next Revolution on the presumed future abundance of oil supplies rejects the pessimistic outlook of limited increases in oil capacity over the next decade. It suggests global oil capacity will exceed 110 million barrels per day by the end of the decade, putting an immediate end to concerns regarding constrained long-term oil supplies. This conclusion is based on an assessment of new projects with a reported capacity of 49 million b/d before a downward adjustment to 29 million b/d to allow for completion risks and reserves depletion. Maugeri holds two PhDs, one in Political Science and one in Economics, and has extensive executive experience with ENI in strategies and developments and in petrochemicals.

In putting forth this optimistic thesis, Maugeri apparently sets aside a variety of technical realities, including the difference between natural gas liquids (NGLs) and conventional oil, reserves depletion versus capacity declines, and proven reserves as opposed to speculative resources.
