And the definition of C1 cash costs leaves out lots of costs which are paid in cash.

I really dont care about some accounting standard derived by a mining industry to allow them to publish totally inaccurate costs.

If you want to be realistic then you need to include all costs which are not capitalised(drilling costs)

Liabilty to pay royalties and taxes have to be accounted for against each barrel of oil. They may only get paid quarterly or 6 monthly but they have to be paid. These are genuine real costs which use up cash.
