New Topic as there seems to be nothing about Shell (the oil bit) yet it has been inthe news for many weeks - - -
FWIW I think the problem is not shell's making ( only the way they portray themselves!) - oil reserves are not an exact science - you only "know" what's there when you've removed the last drop (ie the remainder is uneconomical to extract)....as I underestand it the formulae/processes are not up-to-date and techniques that were acceptable are not used. This gives rise to separate accounting for the same thing -the oil stock. Hence it is very easy to cause confusion even if we are discussing some liquid that "might" exist and at what quality/cost.
Until all the Oilco's get together and redefine their methods there will be suspicions that (this =Sell) problem is likely to be on-going.

I have a small holding in Shell,,bought today in the expectation that there will be a Libyan connection. I don't believe Shell has been "lying" over the years - it's just a knotty problem, discussing something you can't see, or measure.
Ramco =ROS.... I don't hold...has much the same problem with its gas field, but there it looks like the pressure is falling faster than expected - if that's the case then the total value will be less than forecast - and the dramatic fall in shareprice is the result. (bounce today). I don't think it is dishonesty ( although time will tell), but part of the same problem that no-one really knows! How can they? Indeed!

Best regards
