Article: UK Bowland Shale Worth $1 billion, page-6

A billion now equals billions when gas flows. And the multiplier should be higher as development costs will be low. After all;

No pipelines to build
No LNG plant to build
No freight to market
No sour gas
1km thick
Multiple laterals (they do up to 50 per well in us and shale is a fraction of the thickness)
No expensive outlay to buy the ground
No water in the deposit
No 6 years from drilling to cash flow
National shortage of gas
Closing coal down

Billions!!!! The closest thing on earth to literally sticking a pipe in the ground and connecting it to your stove | heater
