I don't know were you got that figures from before 1995, because I take Jean laherrere's study he did with the french geologists perrodon and another fellow (don't recall the name) in 1994 for petroconsultants as a starting point. At this time they estimated a range between around 1600 to 2250 billion barrels for URR of conventional oil. Not long after independent estimates by Jean laherrere led him to believe in an URR of 2150, now this has been revised downwards to 2000 billion barrels. So please cite the reference to these figures,

We are not in disagreement, Rembrandt.  You seem to have forgotten to deduct the pre-1960 URR (723-Gb) from the 1750-Gb tally in that Laherrere/Perrodon/Demaison study.
