The Sakhalin Papers LXIII: The Reserves Ledger — Did Shell Really Lose 1.06 Billion Barrels?
In March 2008, the consequences of Shell’s surrender of control at Sakhalin II surfaced in the language oil companies understand best: proved reserves. Contemporary reports said roughly 1.1 billion barrels of oil equivalent were disappearing from Shell’s books. Shell’s own annual report contained two striking figures — 658 million boe and 402 million boe — which, when added together, appeared to support that conclusion. But they did not describe the same thing. One figure represented minority interests disappearing from a consolidated subsidiary; the other represented reserves being transferred into the equity-accounted investment column. Shell’s actual reduction in proved reserves attributable to its shareholders from the Sakhalin transaction was approximately 402 million boe. The distinction is accounting — but it is not merely cosmetic.

Evidence standard: Shell’s reserve figures and accounting classifications are treated as corporate facts. Contemporary descriptions of a 1.1-billion-barrel “loss” are attributed to the analysts and journalists who used them. No accounting reclassification is treated as a physical disappearance of hydrocarbons. The distinction between reserves surrendered economically and reserves merely moved between reporting categories is maintained throughout.
