The drilling method involves forcing a mixture of water, chemicals, and sand at high pressure down a well bore and into the dense surrounding rock.
This fluid is forced down a newly drilled hole in the rock formation called a well bore at a high pressure.
Bitumen is an immobile, degraded remnant of ancient petroleum; it is present in oil sands and does not flow into a well bore.
It uses a fibre-optic cable inserted into a well bore to build up an acoustic picture of the fracking fluid going into the rock at multiple levels.
Similar tools are available that can seal off and test a formation in a cased well bore or that can bring a small sample of produced reservoir fluid to the surface at reservoir pressures.
(If there is gas present in the formation, the gas may flow from the top of the drill pipe during the test). Similar tools are available that can seal off and test a formation in a cased well bore or that can bring a small sample of produced reservoir fluid to the surface at reservoir pressures.
Alaska already demands that a relief well be drilled simultaneously with a new well bore for production in the Arctic Circle.
In order to help maintain a vertical well bore, the drill pipe above the collars is usually kept in tension.
