SAS,
Gas is not the problem for the field, the killer for any gas field is liquids, and in SLBY case, the more you try to draw down on the reservoir, the more you induce condensates/liquids, the more % liquids you have to try and bring to surface with the gas, then the heavier the column in the production string, which simply results in holding back more and more gas from being produced.
It is why they will have to install velocity strings at some point, as they are closing in on that "stall" window, so introducing a smaller bore production string means you produce through it at significantly higher velocity, which in turn helps drive out the liquids to surface too, this simply delays the eventual stall, sometimes by months, sometimes by years, but the end result is decline, decline, decline.
As for any gentleman's bet, the field will likely never see 9.5 mmscf/d as was being delivered when they initially cracked open the sidetrack to add to the field production. currently they could even go to one compressor with what is being produced, and even if they did manage to revisit 9.5mmscf/d, it would be for such a short spurt that it isn't of note, as that would punish them with lower rates after such a spurt... pointless and not how you deal/manage a significantly depleted gas field.
