sot - some crudes have a significant intermediate fraction (c2 - c6), these are volitile oils. i havent seen a compositional analysis on ghawar, but i wouldnt be surprised if it has a significant fraction of intermediates.
The C1 to C5 content of a barrel of Arab Light is ~4wt%.
intermediate fraction (c2 -c6), by the reservoir engineering definition, refers to the composition of the reservoir fluid, not just the stock tank oil. we usually work with mole %, so i can't really relate to ~4 wt% c1 -c5.
the reason i suspect that ghawar may have a significant fraction of intermediate is based on the reported api gravity, gas/oil ratio and the reservoir temperature (~ 230 degrees F as far as i know).
