Taken from iii....Gramacho.......Looks like about 400 mill barrels + by the time we are finished.

The superb result from 14/10-6 stirred me to work up a simple net pay model for Sea Lion Main Fan to get a better feel for what the forward looking P90 might be.
P90 VOLUME ESTIMATES
It is shown in the attached slide.

The black grids (each mostly 1km2) are in the old P90 area. With the average net pay assumptions shown and using porosity and Sw assumptions from the wells and a 30% RF, which I believe is appropriate, the model shown gives 143 mmbbl for the old P90 area. This is within 10% of the RKH figure of 155 mmbbl. I suspect the distribution of net pay might be more variable according to channel locations and hence it could do with some geological input. Nevertheless its probably good enough for now.
The purple grids show the area and net pay values used for the additional P90 added by 14/10-6. In effect the old mid case/P50 area becomes the new P90 area. This adds a further 70 mmbbl taking the P90 up to 225 mmbbl. The beauty of 14/10-6 however is that it opens the way for an extension to the south west down to the block boundary, which could add a further 77 mmbbl in the red grids and raise the P90 to about 300 mmbbl.
One figure which caught my eye in the 14/10-6 RNS was the Sw = 21% which is the lowest average Sw in the field to date. I am not sure anyone would have put money on the 14/10-6 well having the highest oil saturations yet to be found in the field. It was very welcome, contributing to the OIP and hence reserves.
FUTURE WELLS
14/10-7 is at the northern limit of this model so the pay could be anything from 0 15m. Heres hoping the new 3D interpretation is sufficiently far advanced by mid Sept to locate 14/10-8 3km SW or SSW of 14/10-06 to prove up the southern tail.
If this well were successful I cant help wondering if DES and RKH would agree to drill a lease line well at the 14/10 southern boundary.
The costs could be split 50:50 saving RKH money and perhaps making it feasible for DES to raise the funds if their balance is insufficient
It could prove full extent of Sea Lion on RKH acreage
It would help DES to go on to prove up Shona/Sea Lion South
And it would be useful information for both operators in any field unitisation discussions should Sea Lion spill into the DES block.
LOWER FAN
The Lower Fan pressure comment is puzzling:
Formation pressure tests indicate B15 sand to be in pressure communication with the Sea Lion main fan complex giving significant updip exploration potential.
Unlike previous RNSs there was an almost complete absence of depth information in the 14/10-6 RNS. All we were told is that the B15 lower sand package was below the Main Fan OWC of -2477m SS.
The 14/10-6 prognosis was for the top Main Fan to be 14m updip of 14/10-4 which would place it at -2426m SS. Since the gross reservoir interval was 42m, the B15 Lower sand would have to be deeper than -2468m SS without accounting for non-reservoir sections (shale intervals etc.) that would result in it being significantly deeper.
So with the absence of information it is difficult to read anything into the pressure communication with the main fan complex other than it is interesting to note there was no form of qualification in the statement. Perhaps more insight can be gleaned at the AGM?
For example take the RNS of 11 Feb 2011 Post 14/10-3 also dealing with pressure info
MDT pressure readings taken over Sand 3 indicate that it appears to be lying on the same oil pressure gradient as the main Sea Lion fan in well 14/10-2, indicating the potential for good lateral communication. Further wells and technical work will be required to determine if this is the case.
Exactly 2 months later the 11 April Update post 14/10-4 stated:
Company does not believe 14/10-2 and 14/10-3 to be in communication
Given that there is nearly 30m of 20% porosity sand in the B15 sand at 14/10-6 there is potentially a large pore volume updip to accommodate a significant oil accumulation. A 14/10-8 well SE or SSE of 14/10-6 would shed light on this whilst confirming a further Main Fan P90 upgrade.
I took advantage of recent sp falls to get back into RKH prior to the 14/10-6 well results and believe it is now substantially derisked for most holders. Given time and 2/3 more wells to complete appraisal and grow volumes then there is only one way this sp can go. Looking forward to seeing the sp growth over the next few years as Sea Lion comes on stream.
