Push,

Thank you, we all value your opinions , they are the the best on this BB and iii, and as you say they are your opinion, and we accept that whole hardheartedly (at least I do).

It is a very, very, interesting analogy of what might be going on etc.

Anyway, if its a full zonal approach expect news within a week, if it's zonal expect an update per zone.

Bottom line is the CPR, that is the driver here, and only SS will know how to maximize that baby.

Thanks Push.

Jiffy,

To highlight these are purely my views and open to debate and may well be corrected on Co fact once released.

Typically you do want to test individual zones, this give a far stronger weight to balance out the eventual CPR, but from my take on this there are variations through out the kimmeridge, that is obvious, but mother nature opted to traumatise the lot during the shift and ultimately the extensive fractures now make it as one... there is no way to change that and there is no way to create isolation. therefore the Kimmeridge for simplicity is now one, with different play/formation types interbedded throughout.

Hi Push,

After reading your very detailed explanations of the issues of specific gravity and Nitrogen and Water and Brine etc on iii, and the fact that this is a deviated well, make me think that zonal testing would be very time consuming and imo you explained this very well so that a non oil techie with even a basic understanding of physics might well easily visualize.

I happen to think that with time being a constraint, and the water issue and pressures etc, a total zone approach makes sense. Hence the 14 week window , zonal versus total. If zonal doesn't work just go for total?

Playing devils advocate, would SS want to know what each zone produced? (yes) otherwise why go to the trouble of sinking a deviated well?

Hi penguins,

My take on all the stuff I know and all the stuff i have studied on the general geology of the Weald has whispers of it not being that consistent throughout the whole basin.

Meaning the whole flank from HH to BB and further may well have similar characteristics, thickness. extensive fracturing, more interbedded features etc.. but I do not expect it to be uniform at all N to S, E - W, Brockham borders on such variation, and in my honest opinion I expect Lidsey to be further limited, successful but not on the scale we see at HH or BB.

If there were clays with no permeability/modest fracturing or extensive fracturing then there is zero point to perforate them unless they can fracture them and they can't. So for me, Brockham lives up to my expectations, Lidsey is to show it's hand yet. HH confirmed the concept in spades too.

Does that have a potential effect on the greater weald recoverables ?? of course it would, but I also suspect most but likely not all of the UKOG licence & HH will within reason prove high to medium as you move away, and that might also mean possible isolation can be seen towards the far licence reaches. Nothing to concern about, just the lay of the land.

Hi jiffy,

It is my opinion based on the information provided that the whole Kimmeridge is extensively fractured, the clays may be less giving regardless, but they will provide additional mobility throughout.

I do believe the only logic is to get the well stimulated and flowing as one. Though there may be a small chance that for example the KL-0 may have some isolation between it and KL-1 relative to some findings from the logs or cores etc.. therefore there might be a chance that maybe one or two sections have some chance to test individually but getting as much of ALL the water out from the wellbore and formation is normally the priority.

it also means that once the full wellbore is cleaned up, that IF you were to go back and test a single interval then it is already fully cleaned up and the test will start very quickly.once flow stabilizes, without additional influences due to water hold up etc.

Push2,

I appreciate that that's your view but to provide balance.

The work performed on the Brockham well logs showed that the Kimmeridge has zones within the section that are not fractured. BB may be similarly zoned.

There is also the suggestion that UKOG at BB have also perforated the shale which would mean flowing from zones with very different characteristics.

In the RNS of 20th July there was the following statement:-

'The Company is currently mobilising equipment to perforate and flow test a total combined 900 ft of the Kimmeridge section, beginning with the deepest reservoir zones.'

That was with reference to the BB-1 well not the 1z well and the perforated interval has also been increased but this shows a clear intention to separately test zones, not the whole section - but as with all plans this might have changed but this plan would have been with the knowledge of any operational difficulty associated with separately testing reservoir intervals.

In recent RNS the testing is of 'multiple zones' which could be interpreted to mean either testing the zones together or separately - so we shall see, my view is that there will be zonal tests, the initial flow test of each being RNS'd immediately - whilst the ideal is that nobody leaks the information it does happen.

At HH they released the initial flow rates at 7 am the next day.

That's great Ozzie; I'm sure you could probably smell that oil while you were talking to the guard; in fact I could hear the Castrol GTX advert playing while I read your post!

Push,

So if theoretically we are just testing one large zone as you say in your opinion, then would I be right in assuming that it would be more than likely...... that we may get a notification ie a initial prognosis of initial flow rates that much quicker than doing it by zone by zone?

If you were in charge, would you wait a full 14 weeks of testing before announcing anything?, . I suspect the 14 weeks provides a safety margin to not only establish flow test results but perhaps also provides time for any intervention if required if you know what I mean?
