E2E - Without getting too technoid, gas wells have quite a sudden fall-off in flow rate, so they can't be assumed to be a permanent steady source of revenue like mining an ore body.

When they 're-complete' a well, they have exhausted the current reservoir zone and are moving higher up the well to tap another zone. Each zone has its own characteristics and new (steady) flow rate is unknown until they get past the initial week or so.

In the end all zones have been produced and they need to drill a new well elsewhere into fresh reservoir, this is high cost (multi-$m) and has other risks.

E2E hasn't really disclosed much detail, so it's hard to evaluate longer term potential. Best to not worry too much about fundamentals and just trade the trade. Otherwise you are an investor.
