    Wilton, I happen to know a guy who does drill holes in the foothils with really big rigs. They are on hard times the last while and he had one rig out of the whole fleet working for the last while...and that one was probably only making expenses.

    This isnt your normal drilling job. That fellows firm was retrofitting one rig at I forget how many millions of costs so the derrick could more drill stem. The bigger stem hook load weight was astronomical.

    Just think of the racking required to hold 10 to 15 km's of drill stem. I would say it would be next to "impossible". But thats what real challenges are made of.

    You'r talking man camps and weeks if not months; if not years of drilling time. And any kind of problem and you lose a lot more than just the hole.

    As somebody confirmed...then you need at least two of them. Just reaching 10,000 feet to get to solid granite below sedimentary rock is a feat in itself.

    I forget the details; but years ago the Russians were trying to drill to a record setting depth and I think they twisted of because of pipe failure from the extremes of pressure and heat.

    A good mud pump would be essential; and the mud man would earn his keep

        About 40 years ago my brother trenched in horizontal geothermal in his farm yard with the expectation that several buildings could be heated and cooled. The system was rot with problems and it was a good thing that he still had his furnace. Now, with natural gas to fire our chambers, I think we already have clean emissions.

          Good video. I remember hearing about this years ago in a college geology class. Same thing the heat put an end to further progress. Even so if we could identify the "hot spots" on the prairies where shallower holes would yield some good heat it would cost astronomically.
