WG,
Booster compressor has been in the outfit references for well over 2 years, but it is something that "should" only be utilized once they have used commercially viable options on the actual wells FIRST.
Reason being that well production solutions and production string solutions have the potential to alleviate the the surface pressure issues "potentially" for a considerable time.
And the booster compressor ONLY enables the main compressors to function above threshold, it does nothing for the production of liquids or well condition, ONLY installing a booster compressor and doing nothing else will seriously impede the life production of the field.
As for A4 water production, I have discussed this in detail over the last couple of years, and the main reason for A4 contributing the vast majority of the produced water is that the well trajectory was poor, and dips down to near bottom of reservoir BEFORE changing direction while drilling and shifting upwards more towards mid reservoir, therefore the gas entering the well in the latter part of the well is met with BANKED condensates and possibly a SMALL amount of reservoir water which is being forced out of the well with the gas.
The latest water volume is not that big, around 18 bbl/day, hardly earth shatteringly high, and it is also fact that condensate creation also has water induced from that condensation effect, maybe not all but a good portion of the banked condensate also contains BANKED induced water too.
In part, the BANKED condensates and induced water is likely from ALL past and present wells, being that the density of both liquids means that a proportion of condensates and water generated in the near wellbore reservoir and in the well as it produces does not make it out to surface, and can simply fall out slowly to bottom of reservoir, only to be collected by any well that intersects that low lying area of the reservoir.
A4 potentially has options, they could for EXAMPLE, run a production tubing that extends further into the wellbore so the tubing end is past the low point and into the higher point in the well which would avoid some or all of the banked liquids, they could as noted in the CPR, install a jet pump to assist the lifting of liquids and ease the back pressure.
Ultimately they cannot stop liquids being produced in some quantity as that is part of the reservoir depletion condition, and the dew point effect, but it is manageable, and they "can" apply solutions that WILL make a big difference.
