$this->bbcode_second_pass_quote('Darian S', '
')What caused the shale revolution, why didn't it start earlier?
In natural gas it did, with shale production dating back to 1825. Shale oil was being produced by the 1880's, in both Ohio and West Virginia.
The recent surge is more of an intensification of something already known about, and previously produced in naturally fractured sweet spots. Devonian shale development in OH,PA, WA for example, the Marcellus being probably the 3rd, maybe even 4th burst of production from that rock.
Peak oilers don't tell you any of this because it doesn't help their advocacy of doom tomorrow.
$this->bbcode_second_pass_quote('Darian S', '
')Was there some revolutionary technological advance that allowed it?
In 1825 it was drilling a hole into it. In the later 1800's it was deeper drilling, wire rope being one of the main innovations that allowed cable tool rigs to go deeper. Again, peakers don't want to discuss any of this, because it doesn't allow doom tomorrow afternoon. Plus, they are generally ignorant of any history of the industry because..well...they prefer that state, having no desire to understand the issue before turning it todays rapture scenario.
