Aug 22, 2023 · 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. The presence of weak anisotropic shales within the sedimentary sequence can be shown to be an important control on toppling instability. The location of the shale formations whether at the toe, mid slope or near the slope crest will influence the failure mechanism and is the subject of ongoing research.Shale is a rock that has been formed from the compression of mud over time. Some black shale contains organic compounds that can be converted to oil or natural gas. Other colors of shale are crushed and mixed with water to create clay.The oil recovery in shale oil reservoirs is less than 10% ( Sheng, 2015a ), or 3–6%, according to the EIA 2013 report ( US DOE, 2013 ). The oil recovery in tight formations is also low. The gas recovery is 15–25% (Kuuskraa, 2013). A large percentage of the oil remains unrecovered without enhanced oil recovery (EOR) methods.Shale.
