Ann: Sino Gas - Operations and Commercial Update, page-101

Agree not a stupid.

Blind Freddie can see in a normal exploration campaign for tight gas. You might drill ten wells Max as proof of concept. Test fracked them for months to work out how to get the max recovery.

No sane explorer would drill 120 wells and still not know if the gas can be produced above a commercial threshold.

But don't worry the MD knows what that is but he not willing to tell u the shareholders.

Rubbish methodology in my view
