Targeting a maiden 2P reserve booking of 500PJ Given the huge data set and consistent interaction with reserve auditors GLL are of the view that a 500PJ 2P reserve booking is likely even if only modest gas flow rates ( 0.25mnscf/d) are sustained. Applying historic 2P transaction multiples (which are becoming increasingly relevant, in our view) to a 500PJ booking yields $925mn or $4.80ps (see figure 13).

Don't know the answer to your question no expertise in that regard but you appear to quite rightly point out difference is terminology. Cannacord describe the flow as mnscf/d
Galilee describe the flow as Mscfd
Perhaps OGP can help us out.
