Morphology

shale + oil

The compound denotes oil that comes from shale rock, which is a straightforward noun+noun composition: 'shale' (a type of rock) + 'oil' (the fuel/liquid). Although the technical extraction methods (fracking/horizontal drilling) are specialized, the basic meaning 'oil from shale' is directly inferable and cross-linguistically transparent, so a B1 learner who knows both constituents will likely understand it.

Etymology

Shale oil is called this because the oil comes from underground shale rock that must be drilled and cracked to free the oil. Because the oil is trapped in small spaces in the rock, it is also called 'tight oil', and the name explains its modern meaning.
