The Oil Casino: SEC Heading for Monte Carlo

This is a long article on the subject of oil and gas reserves and due diligence.

My purpose is to alert you to the revision of SEC Regulation S-K and Regulation S-X effective January 1, 2010. Concealed in a handful of benign new regs is a financial truck bomb that's going to blow away "proved reserves" as a meaningful metric of oil company assets.

Old definition: Proved Reserves are those quantities which can be estimated with reasonable certainty to be commercially recoverable from known reservoirs under defined economic conditions. Proved quantities are limited by the lowest known hydrocarbon as seen in a well penetration unless otherwise indicated by definitive geoscience, engineering, or performance data. Seismic data alone is not sufficient to define fluid contacts. Undeveloped locations may be classified as Proved in undrilled areas of a reservoir that can be judged with reasonable certainty to be commercially productive.
New definition: Industry is no longer constrained by the criterion of certainty. An operator can book incremental proved reserves from planned enhanced recovery projects (gas injection, acid fracturing) based on a pilot project. Coal seam gas, bitumen, oil shale and other unconventional resources can be booked as Proved Reserves. Estimated reservoir properties in the aggregate is a departure from the old rules. The new SEC definition does not require that an analogous reservoir has to be in the immediate area or in pressure communication. Seismic analysis and reservoir models are sufficient to book Proved Reserves.
Hold on to your shorts, it gets worse.
