Although not all of this can be extracted, it is more than three times the proven petroleum reserves of Saudi Arabia. Oil Shale, Shale Oil, and Oil-Bearing ShaleShale is part of mudstone and claystone but can be distinguished based on structure. Shales are fissile and laminated. The fine lamination is what makes it economically viable as it can store gas between the lattices in free form. Shale is observed in different colors like gray, black, green, brown, or even yellow.Shale formation is fine partiles that can remain suspended in water long afrer the larger particles of sand have deposited. Shales are typically deposited in very slow moving water and are often found in lakes and lagoonal deposits, in river deltas, on floodplains and offshore from beach sands.Shale Formation. A shale formation is a sedimentary rock composed of fine-grained detrital mineral (silt-size particles of quartz and calcite) and flakes of clay and it is characterised by the presence of about 1% to over 20% of Total Organic Carbon content (TOC).
