Ann: Glenaras Gas Pilot - Gas Production Update, page-29

It is nice that they finally have some gas breakthrough but how is this meant to be scalable given they've also got the pilot located in the lower risk part of the acreage and yet it is still rather average in terms of results.

The basin/acreage here is known to have sandstone aquifers in direct contact with the coals, meaning you essentially need to produce water for a very very long time and in high quantities to drain the aquifers so that you can de-pressurise the coals and have gas widespread gas desorption. You can even see signs of possible water recharge in it already with this current pilot given the huge water quantity they have produced so far. It may not be that there is any aquifer connection to the coals at the wells (which I think they have said in an earlier announcement) but it does not mean that the there is connection away from the wells. Even if this pilot does eventually manage to de-water the coals and show high gas rates in the centre wells, drilling horizontal wells at this tight spacing will not be economic for a full field development?

It may be that in this sweet spot where they have chosen to do the pilot that you do not have as much of this sandstone aquifer / coal connection but it is widely known in the industry that the majority of the Galilee basin is not like this and it is a huge risk to a potential project. The business of draining aquifers is not one many want to be a part in or I am sure this acreage would have been swallowed up by Santos/Shell/APLNG a long time ago. They struggle enough with this aquifer issue on some parts of the Surat where they choose not to produce from and completely shut off the top coal to the wellbore due to this risk.

I reiterate what another poster has said, it would be a horrendous development based on what we know today. But happy to be corrected.
