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.
Shale is basically formed from the lithification of multiple layers of fine sediments that have been compressed by the weight of additional sediments from above, and cemented together by clay minerals over time as fluids are squeezed out.
Shale oil is mined above ground in an open pit or underground. Traditionally above ground open pit mining methods are used. Water is used heavily in the process and groundwater must be pumped out.
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.
Expense
Processing, mining, and waste disposal is expensive.
Very similar, yes, but without the lamination that shale exhibits.
Solar and wind renewable energy, of course. Oil shale and tar sands
That would be "Oil shale" - shale is a kind of rock. Anyway, the oil shale is dug up and then hot, hot steam or other substance is run through it to make the oil runny enough to flow down and out, where it is then collected.
Shale oil is an oil distilled from shales and used as fuel

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.
