WG,
The SLBY story was in place "before" gas prices went through the roof, it was deemed viable then, and it remains so, but not to the benefit of retail, as the debt that should not have been required has kept it under water, and will continue to do so.
As for the Barg story, I will not agree with you on that one, simply because you fail to recognise the most important factor here is the reservoir pressure, and the rate/speed of pressure build up recorded on well shut-in.
The CPR clearly shows the pressure data, and that surface pressure recovers fairly quickly to "near" reservoir pressures (70-80 barg).
This is because when shut-in, any heavier liquids within the flowing column stop when the well gets shut-in, and then they simply drop out to bottom, and this leaves the production string only with gas from top of reservoir to surface, and that can transmit the reservoir pressure and speed or replenishment quickly and accurately.
So even if the pressure hits the "compressor" limitation of 17.5 barg, then they either have to choke back a little to reduce the amount of liquids being produced, which lightens the column of flowing gas to surface and increases the surface pressure. OR get on with the velocity string change out/s, which will give them higher surface pressure as the velocity string has an easier job of lifting liquids out along with the driving gas.
Basically, if the field produced NO liquids, then the flowing surface pressure today would be well over 50 barg, so it is as always is with ANY hydrocarbon field, a constant effort through various methods to maintain or lower flowing column weight and keep the gas flowing as cleanly as possible.
