The mining of oil shale requires conversion of the solid hydrocarbons in the rock to liquid form, so that they can pumped or processed.This is done by heating the rock to a high temperature, and separating and collecting of the resultant liquid. This heating process is called retorting.
hot metal-rich fluids
semi-arid conditions
Petroleum is in a liquid form. It is retrieved by drilling into the earth and then pumping it out. Oil rigs and derricks. Various means of obtaining petroleum from tar sands and shale deposits are being investigated. Tars sands are not expected to be "mined", but treated in situ to generate liquid / gaseous petroleum. Oil shale may require mining. Neither of these is currently economically viable.
Dig a large pit over an underground ore body, dig out the ore body, process the material from the ore body to extract the desired material (e.g. coal, metal, oil sand/shale). When done the pits used to be abandoned, now in the U.S. the EPA requires remediation.

Processing, mining, and waste disposal is expensive.
You don't make oil from shale, you extract oil from shale. The shale acts like a sponge, sometimes the shale is so porous that the oil can be squeezed or sucked out, otherwise it can be extracted by crushing and heating the shale.
there is limestone, shale,sandstone, coal, zinc, iron, gold, lead, oil/gas,mining

Shale oil is an oil distilled from shales and used as fuel
The reason that oil shale is not used to produce oil is because this is what keeps the oil well from collapsing after the oil is removed. If the oil shale were mined, the oil well would collapse into a large trench in the ground.
one has oil shale and one dosent
It does not matter where oil comes from it is bad for the environment shale oil is just a Les efficient source of oil.
Oil is not mined it is drilled except for oil shale which is mined. Shell in the past has mined for oil shale. Click the link.
Only Estonia has oil shale.
