Sorry to rain on your parade but anything that's 60 miles below the earths surface is going to require a awful lot of energy to bring to the surface.
What is the source of methane hydrate?
Methane from onions! Many old timers swear by this theory, especially if they're fried.
BTTT!!!!!!

Yeah...shale oil was so profitable...let's go for some 60 mile deep marble methane now.
Come to think of it, though...maybe that's how the Mole Men in Underdog were so successful. Could it be that they had marble methane long before we Surface Men even dreamed it up?
I, for one, have never believed that either came from the decomposition of organic matter.
It's been here since the formation of the earth.
Gas does exist at great depths, and it's conceivable that as it percolates through some porous rock it will cool and depressure enough to allow it to become condensate.
Of course, the limiting factor is the presence of porous rock.
At 60 miles below the earth's surface the overburden pressure is about 300,000 psi. I visualize the rock as being a solid, impenetrable mass.
If there is a regeneration of gas and if it does percolate through the mantle and crust with that much pressure and through that much rock, what keeps it from coming to the surface as a gigantic blowout?
The rock above the crust is much less dense than the crustal rock.
Thanks for the ping, B4. It's work time.

Is there non-organically derived marble? Marble is metamorphicized limestone; which is in turn derived from deposits of shell, coral, etc., in sea beds.
I suppose it's possible that there is precambrian or even pre-life limestone and thus marble. The carbon had to be somewhere.
Do you have a reference to such? The deepest well I've heard of is only 12,000 meters. That's far short of 20 miles.
The temptation to post pictures of fart-lighting is almost more than I can stand, but I'll try to restrain myself.
The article really presents nothing new - except perhaps to the author. Abiogenic methane is known from the creation of the solar system.
"If methane gas was always the product of biological matter, then detecting methane in the atmosphere of another planet would be a sure sign that some sort of life form had existed there at some point, said geologist Barbara Sherwood Lollar of the University of Toronto."
Where do they get these people?
Would n't this mean that in or near a volcano you should be able to find Methane?
I remember some guy started drilling for gas in an old volcano crater in Europe and didn't find any. His idea was the same as this one.
"methane gas more than 60 miles below the Earth's surface"
I wonder how they are plannig on getting down that far. From what I know the largest rigs can only go to about 35,000 feet. How in the world would you pull a pipe that long out of the ground in order to change the drill bit.
