I have to give credit to the latest CPR, it does contain a notably much larger amount of more established info, and is far more interesting than the more sketchy previous ones, which had much less info to work with, other than the OLD pre Angus data to establish their outputs.
I find it strange that the CPR data does not match that info stated by Angus in their quarterly flow reports, meaning Angus have pretty much maintained that condensate production is running at approx 160bbl/d, when infact the CPR that has all production data, states differently.
The CPR data shows roughly 80bbl condy per day from both A4 & 80bbl/d from B2, so yes 160bbl/d, but they are also getting 40bbld from B07T, which is not included, as it is noted that the condy from B07T isn't meeting the required grade for sales, likely because of the additional unwanteds affecting the quality, so it is likely once it does clean up more fully, then the total daily condy from the 3 wells will be around 200bbl/d, it could already be at that grade now they are into plant with B07T and not drawing it off separately to the welltest separator.
The current total water production isn't that high, it peaked earlier in the year from A4, at around 35bbl/d, and has dropped off to closer to 18bbl/d, but that includes a lower gas contribution too. there will be contributing factors to A4, which include brines etc that were used extensively during the completion phase of B07T, and that will include a notable amount that will have dropped from the well into the lower reservoir, and is being slowly collected via A4, and yes there "may" be a nominal amount of very low lying natural formation water, but is not of great significance, it is also likely "some" of the water is drop out from the other 2 wells, as all are contributing condensate, that water simply part of the "banked liquids" near bottom of reservoir.
The CPR data for A4 is skewed a little, showing earlier months this year as high water contribution and lower gas, but the pressure and flow chart shows that this is actually because the well had a few notable shut-in periods during that time, likely in part to the compressor failure and the need to lower total contribution until repaired.
Personally, typically 18-20bbbl/d of water total, isn't that much to deem it an issue, the well is still coping with it, and they do have a plan to help counter that, with velocity string and even jet pump to help keep the heavier density liquids moving to surface.
For the field, some may think, well just slow production flow, that will make much of the liquids drop out, giving mostly just gas, they can do that, but it isn't a solution, it will magnify the problem of stalling the wells flowing faster, as the near wellbore reservoir becomes choked with fall back liquids, and that is not what is needed for long term field life.
