Shale, like all sedimentary rocks, forms as a result of the compaction and cementation of materials that have weathered and eroded off of other, pre-existing rocks.A 2015 Harvard Business School/Boston Consulting Group analysis estimates that shale development created roughly 2.7 million U.S. jobs in the first decade of the shale revolution. A 2013 study , commissioned by the U.S. Chamber of Commerce, projected fracking will create a total of 3.5 million U.S. jobs by 2035.Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks: It is shale or clay slate containing pyrite. Decomposition of pyrite by weathering forms sulfuric acid, which acts on potash and alumina constituents to form alum, which often occurs as efflorescences on the rock outcrop. As the formation contains kerogen originated from algae, it is also classified as marinite-type oil shale.Shale oil resources and exploitation The Monterey formation has long been recognized as the primary source of the oil produced from other formations in Southern California; the Monterey itself has been very productive …The Paleozoic rock sequence consists of the Jodhpur, Bilara, and Nagaur formations followed by the Badhura and Bap Formations, mainly composed of clastic and rocks (sandstone and shale) with ...The thicker the organic-rich shale is, the higher the enrichment degree of shale oil will be. At present, there is no unified understanding of the lower limit of shale reservoir thickness. In the U.S., the thickness of shale formation is defined as no less than 30 m, and the thickness of effective shale is no less than 9 m (Wang et al., 2010).Oct 19, 2023 · A sedimentary rock, oil shale is found all over the world, including China, Israel, and Russia.

The shale gas geological resources of the Longmaxi formation in South Sichuan, China, are as high as 2.25 × 10 12 m 3.Minor precipitation also takes place, and all these fine sediments become a fine-grained sediment rock called shale. When deposition is under reducing conditions, carbonaceous or black shale formation takes place. In carbonaceous shales, the presence of heavy minerals like uranium, vanadium, and zinc has been observed.Red shale.

Shale Gas Extraction. Shale rock formations have become an important source of natural gas in the United States.Shale is a type of sedimentary rock, a rock formed either from the remains of organic creatures or from shattered pieces of older rocks. In shale’s case, layers of ancient silt and mud underwent extreme pressure that compounded them into thin sheets of striated rock. Shale is strong but brittle. It easily breaks into jagged shards. Deep shale layer in the Lower Silurian Longmaxi Formation, southern Sichuan Basin is the major replacement target of shale gas exploration in China.
