Re: US gas 1/3 price of UK gas.
Make that over 4 Million onshore US wells...
over 35000 new wells drilled each year in 2012 and 2013... (baker hughes well count) By comparrison the UK has just over 2000 wells drilled in the UK onshore since 1902
We (as in Europe) don't have enough rigs to even contemplate a shale gas revolution yet. The huge land banks, rig numbers and experienced personnel are huge obstacles to progress. Added to which is an immensely challenging planning regime which causes huge delays, which is a problem given decline curves for shale gas wells are precipitous and require constant infill drilling.
The scale of the challenge is truly gigantic.
