Ann: South Erregulla Update, page-253

Going through the release and some old releases I notice SE3 shut in pressure has raised to 431psi going back to WE5 data WE5 with its completion /skin issues it sat at around 260 psig flowing well head pressure.
Obviously shut in pressure and flowing pressure two different things but obviously room for gas and not just completely water filled the reservoir


So the regions Aquifers potentially seeping into these gas reservoirs ?


either over millions of years through the fractured fault lines or drilling fracturing the surrounding rock and creating pathways ?
can the weight and pressure of an aquifer overcome the pressure of the gas , then could also the pressure release be filled by water and/or a venturi effect?
above my intellect but plausible reasons the data where 2+2 isn't =4
