This is an extract of an article about Shell's reserves adjustment:

"More than 90 per cent of the total changes made by Shell relate to a reduction in the "proved undeveloped" category of its reserves and the balance is a reduction in the "proved developed" category.

Of the restated reserves, two thirds relates to crude oil and natural gas liquids and one third to natural gas.

Shell said the restatement of reserves would not have a material impact on production in the near term or the volumes expected to be recovered. But the FAS69 standardised measure of discounted future cashflows associated with the proved reserves would be impacted, Shell said.

The affected reserves were mainly booked from 1996 to 2002, and the largest impact of the change will be in Nigeria and Australia. Shell said the recategorisation would bring the global reserve base up to a "common standard of definition," consistent within the exploration and production business."

Much of the reserves reduction in Australia are the same ones you are suggesting WPL include in their proven reserves.
