bingo!

"The analysis concludes that approximately 60% of the total gas production is from the uppermost zone (zone 6), about 27% from the middle zones (zones 3, 4.1, 4.2 and 5) and about 13% from the lower zones (zones 1 and 2). Importantly, all the water is evaluated as being from zones 1 and 2.

This is a very significant outcome, as it presents a practical solution to resolve the inflow of water to the well bore in order to enable the optimisation of the gas flow rate. A retrievable isolation bridge plug will be set at the top of zone 2, thereby sealing off the formation water."
