one is deep, the other is shallow.
The Kola Superdeep Borehole was begun in 1970 and finished in 1992. It reached 12,262 meters deep. Work ceased due to the difficulties of drilling in extreme temperatures (~300 degrees Celsius) and lack of funding.
It is more than 4 thousand feet approx 7.3 miles deep
Finding and drilling for oil deep in the ocean.
Quite simply because you have to drill deep enough to get to the substance you require be it water, oil or gas.
Drilled Hole: a deep hole drilled into the ground to obtain samples for geological study or to release or extract water or oil Usually narrow in width. Probably the most common type is a water borehole, which is where the borehole is used as a water well.

Produces a deep ringing when struck.
The deepest man-made borehole in the world is the Kola Superdeep Borehole (Russia, 1989) at 12,262 meters (7.6 miles). The deepest natural ocean depth is about 6.8 miles (11000 meters), in the Marianas Trench near Guam.

Russia, China, Venezuela and much of Europe drills off of our coast. We should be banning deep water drilling and allowing drilling closer to shore where it is safer and more cost effective. The only plan that could be more foolish then the one we are now chasing is to try to cap this drilling and tax... Perhaps you have heard of such a foolish idea lately?
