Very similar, yes, but without the lamination that shale exhibits.
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.
Yes, shale is considered a common rock. Also, out of all the sedimentary rocks, it is the most common one.
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.
Its limits are 30 to 35 degrees.

Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.

If the mud has lithified into shale or mudstone, then metamorphosed, the answer would be slate.

The value of mudstone and shale can vary depending on factors such as quality, location, and market demand. Generally, mudstone and shale are not typically high-value commodities unless they contain valuable minerals or resources like oil and gas. Prices are usually determined through negotiations with buyers and sellers in the industry.
