Ok so my take on the recent Booster RNS.
To give a simplified understanding of the negative effects of the "induced" liquids that are fundamentally the main issue at SLBY.
If you take a garden hose and empty all the water out of it and then blow down that hose, you feel almost no resistance, meaning you can blow down one end and feel the air immediately escaping at the other end.
In a gas field this is the holy grail, gas production without liquids, means there are almost no barriers hindering the gas escaping from reservoir and all the way to surface.
If this was the case at SLBY then you would see massively higher gas flow for the life of the field.
Now if you take even just a pint of water and pour it into your garden hose and then try blowing down the hose, you will likely almost burst a lung trying to push that liquid along the hose for your breath to escape at the other end.
This is what it is like at SLBY, the majority of the liquids produced at SLBY ate condensate and a little water (both products of when a gas reservoir/well production hits the critical "dew Point" .
For simple effect understanding, if your BBQ gas bottle is running your BIG BBQ on low,, and you feel the bottle after say an hour, it may feel colder than the ambient temperature outside, now turn the BBQ on full blast for an hour and you will see ice forming on the outside, usually a visible line where the LPG liquid is turning to gas vapour inside the bottle.
So effectively your gas flowing has created a condensation or liquid.
In the well and near wellbore reservoir, a similar effect is happening, the gas is flowing from the depleted reservoir, and the lower pressure and temperature causes "induced" condensate to form, and now the reservoir is not only trying to drive out the gas, but also trying to drive out liquids, and it suffers the same effect as you when you tried to blow out that little bit of water in your garden hose.
The Liquids being induced/generated at SLBY ultimately hold back the gas trying to escape to surface.
The booster allows Angus to open the wells more, and the booster compressor is drawing from the well flow line, in turn this allows the free gas to come to surface at a higher velocity and in turn that also encourages that liquid that has been building up down hole to come out to surface too, result is you get increased productivity, at least for a reasonable time.
