Doubtful. And the petroleum and service companies generally know how to drill in rock without snapping bits off.
Precisely. One look at the rig, and maybe they can drill water wells with it in soft sediments, but it does not look very substantial for drilling even well consolidated sedimentary rock.
Workover rigs around here (Williston Basin) are much more substantial.
It looks like whoever tried to do this underengineered the project.
The new, high penetration rate developments I have seen involve using mud motors (which would likely require a lot more pump than they have) and a more substantial drill string as well.
Performance has never been cheap.
I won't speculate on other possibilities, but as far as drilling a hole in rock, the oil industry is the place to go for answers.
