If they find 2000PJ of NG and 200BCF of He that would add 700PJ delivered over 20 years so 35PJ or $50M PA with NG and $300M total of He at $50 per 1000cf

To clarify ideas..
NGas
2000PJ @ 30%CTP share =700PJ @ $1.50/PJ
=$1B

Helium
200Bcf @30%CTP share=70Bcf @ $50/1000cf
=$350M

The SOA suggests much greater resource in the Southern A than the above.
