RE:Infrastructure As to geomanx02's question as to how quickly this field can be commercialized I would guess 3 years to a crash limited basis assuming everything zips along. I base this on the Trans Alaskan Pipeline which alone took 3 years to build under extremely difficult environmental and logistical issues.
Right now in the US alone we have like 100,000 experienced oil industry related workers unemployed or underemployed: 10,000 from the from the canceled Keystone Pipeline, many more from deep water projects stopped, fraking curtailed, pad drilling and other technological innovations, etc.
Then we have the cost: using the difficult Trans Alaskan Pipeline as the worst example it cost 8 billion in 1970 dollars or about 24 billion in today's dollars five or take a few billion here or there.
Therefore I will throw a dart on a board and say this field will initially cost at least 20 billion US to achieve initial commercial production.
