So long as any audit takes account of the amount of messing around with oil prices committed by govements as well. The oil copmpanies are not whiter than white, but neither are politicians.

Stop for a moment and think which goverments tinker with the oil market.

OPEC are the biggest example, openly aiming to rig the market, and almost every other major player is at it as well, sticking a sudden windfall tax on the oil companies*, or relesing reserves for a few weeks to help with a cold snap or opinion poll.

This will not stop so long as oil is so vital to us.

* the UK, Venezeula, and possibly Nigera, have all put major new taxes on oil production recently.
