shale gas, natural gas obtained from sheetlike formations of shale, frequently at depths exceeding 1,500 metres (5,000 feet). Shales are fine-grained sedimentary rocks consisting of silt- and clay-sized particles that were laid down hundreds of millions of years ago as organic-rich mud at the bottom of ancient seas and tidal …Diatoms, bacteria, and other organisms were slowly deposited, forming the first phase of organic-rich shale at the bottom of the Niutitang Formation. Subsequently, with the movement of the plates, a strong tension occurred in the interior of the continent and deep fractures appeared in the basement rock stratum, causing upwelling of ...Shale gas exploration in the UK. The main rock formation of interest for shale gas exploration in the UK is called the Bowland Shale Formation, which occurs across a large area of central Britain. These shales were deposited in marine basins during the Visean and Namurian stages of the Carboniferous period (between 347 and 318 million years ago ...This group of fossils takes its name from the Burgess Shale rock formation, named by Walcott after nearby Mount Burgess in the Canadian Rockies. The Smithsonian's National Museum of Natural History currently houses over 65,000 specimens. The museum also has a permanent exhibit of the Burgess Shale fauna near the Dinosaur Hall.The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America. Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, [3] it extends throughout much of the Appalachian Basin. [4] [5] [6]

The Chang 7 3 Submember is deposited in the period of high lake, mainly containing a sequence of organic-rich shales with thin sandstones. Fu et al. estimated geological resources of 28.8 to 43.2 billion barrels in the first type and prospective resources of 21.6 to 28.8 billion barrels in the second type in shale play [ 56 ].Red, Brown, and Yellow Shale. Shales that are deposited in oxygen-rich environments often contain tiny particles of iron oxide or iron hydroxide minerals such as hematite, goethite, or limonite. Just a few percent of these minerals distributed through the rock can produce the red, brown, or yellow colors exhibited by many types of shale.

The Jebel Oust region (north-eastern Tunisia) recorded two levels of marine black shale in the Lower Cretaceous marly series. Geodynamic evolution, biostratigraphic and Rock–Eval analysies allow classifying those black shales as unconventional shale oil resource systems that were deposited during two oceanic anoxic events: the Middel …

This article defines oil shale and discusses its origin, reviews the resources of world oil shale deposits, and outlines the methods of extraction of combustible ...The kukersite oil shale of Ordovician age in Estonia is part of the Baltic oil shale basin and was deposited in shallow marine environments. The deposit is one of the world’s highest-grade deposits with more than 40% organic content and 66% conversion ratio into shale oil and gas. Commercial grades of oil shale, as determined by their yield of shale oil, ranges from about 100 to 200 liters per metric ton (l/t) of rock. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands. Others have suggested a limit as low as 25 l/t.They typically form in environments where muds, silts, and other sediments were deposited by gentle transporting currents and became compacted, as, for example, the deep-ocean floor, basins of shallow seas, river floodplains, and playas. Most shales occur in extensive sheets several metres thick, though some develop in lenticular formations.

During the process as sedimentary rock materials were deposited, microscopic organisms were occasionally stuck in the deposits. When these organisms decomposed, natural gas was left behind (Soeder and Kappel). The main ingredient of shale is clay which is here on the way from the disintegrated rock higher in the mountains to the sea where it will be finally deposited.

The USGS Energy Resources Program has studied oil shale resources of the United States, with a significant effort on the Eocene Green River Formation of Colorado, Utah, and Wyoming. This formation contains the largest oil shale deposits in the world. Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is converted to crude oil when heated.The development of shale gas plays has become a "game changer" for the U.S. natural gas market.
