Then, first phase, you target something on the order of 1/2 of estimated possible production. And ramp up from there. Call it 2-3 years on a ''crash'' basis, 5 on a ''normal'' basis.
Once the process is started, it's self-propagating, assuming only that new shafts are added on a systematic basis.
What I can't figure out (doubtless Shell have figured it, of course) is how to capture the liquid fractions. Why won't they just seep away?
Any thoughts, folks?
They probably suck em out and distill them into liquid.
