Atwood Achiever - On the Move, page-9

Another way to say it is, given Toubkal is 1.98 larger to PVD than FAN-1 is to FAR (135mmbbl vs 268.64mmbbl best estimate), PVD at 52c for Toubkal is equivalent to FAR at 1.6c for exposure to FAN-1. Both companies have exposure to a secondary drill, further targets in the immediate area and other targets in other countries. PVD has better economic terms, FAR has overspent on FAN-1, but FAR has other drilling happening much sooner. You can't directly compare SP's but in theory on the maths for exposure to each drill that's essentially a reference point - 1.6c.
In pointing that out I do not in any way mean to say PVD will go to the equivalent of FAR's ~9c from that point before results, only that 3-4c (or ~$1 in PVD land) could be achievable. I think FAR has gotten ahead of itself on the back of a significant investor applying buying pressure that i'm not sure can be substantiated from the public facts.
