Re: Upgrade of Contingent Resources to 2P Reserves
PLUS the Upgrade of Prospective Resources to Contingent Resources
The Original Feb2009 RPS CPR showed an Upside Contingent Resource of 166MMbbls for Bentley Field alone – see below!!
This specifically EXCLUDED East Bentley [referred to as Prospect A] AND the West Jurassic [referred to as LeadB] and it also Excluded the West Dornoch AND the South East Jurassic.
THEN later in 2009 - XEL declared that 3D Seismic implied the Bentley Field [Excl. East Bentley &c..] to be 200MMbbls – see below.
Now with 9/3b-6 the East Bentley [Lead A] has come into play as an "Upside structure"
Therefore 70MMbbls [the E/B Upside] I believe should be ADDed to the previous 200MMbbls!!
Then there remain to be accounted for:-
1. The West Jurassic [MMbbls tba]
2. The South East Jurassic [Oil Found in top 15ft - MMbbls tba]
3. The West Dornoch [MMbbls tba]
4. The East Bentley Gas Cap – if it Exists – to reduce OPEX by 5%
I therefore suggest the Upgraded Reserves [2P??] Figures for Bentley AND East Bentley will be declared at 270MMbbls.
This leaves W.Dornoch; WJurassic; and S/E Jurassic to be Declared as Prospective Resources. The East Bentley Gas Cap has also to be declared intact and commercially viable.
I have tracked the Build Up of these Resources from the RPS 2007 Resources Report to see how they have been - accounted for / not accounted for - in order to see where Reserves/Resources are going to end up!!
I suspect Next CPR will show 2p of 270MMbbls from Bentley AND East Bentley Combined
With Prospective Resources - from the other 3 Prospects [WD; WJ; and S/E Jurassic], being upgraded and declared as ADDITIONAL Contingent Resources.
