Shale formation.

Jun 24, 2015 · The way shaliness affects a log reading depends on the amount of shale and its physical properties. It may also depend on the way the shale is distributed in the formation. Shaly material can be distributed in the formation in three ways: Shale can exist in the form of laminae between which are layers of sand. The shale formation thickness will also affect the shale gas production. High shale gas production is easier to be achieved for thick shale reservoirs (Fan et al., 2020). 2.2. Drilling factors. The purpose of drilling is to form an effective channel between shale gas formations and wellbore.Four Cretaceous-aged formations are exposed in Mesa Verde National Park. From oldest to youngest, they are the Mancos Shale, Point Lookout Sandstone, Menefee Formation, and Cliff House Sandstone. During the early Cretaceous, this part of the continent was deep underwater, as evidenced by the fine-grained, dark gray to black Mancos Shale.Gamma ray (GR) logs measure the natural radioactivity in formations and can be used for identifying lithologies and for correlating zones. Shale-free sandstones and carbonates have low concentrations of radioactive material and give low gamma ray readings. As shale content increases, the gamma ray log response increases because …The rock units that occur between the Marcellus Shale and the Utica Shale follow this trend. In central Pennsylvania, the Utica can be up to 7000 feet below the Marcellus Shale, but that depth difference decreases to the west. In eastern Ohio the Utica can be less than 3000 feet below the Marcellus.

One of the first places hydraulic fracturing technology was used was the Barnett shale formation in northern Texas.

The shale reservoir in the Fuling shale play is the Longmaxi shale formations, which are the Silurian-age marine-deposited shale formations and contain abundant natural gas resources. The Fuling shale gas play consists of three large sections: upper, middle and lower Longmaxi shales, and the gross thickness of the Longmaxi formations …

Tight gas is natural gas trapped within a rock with extremely low permeability —typically limestone or sandstone. This is not to be confused with shale gas, which is natural gas trapped within shale formations.

Shale blocks were obtained from an outcrop of Longmaxi Formation in Yanzi Village, Changning County, Yibin City, Sichuan province. The area is located in the west of Hubei and Chongqing ...These perforations allow communication between the well and the shale formation for hydraulic fracturing fluids to be injected into the reservoir rock surrounding the lateral at high pressure. The perforating is done in relatively short segments of the well, typically 150-250 feet long, which are known as stages.The Bakken Formation consists of a lower shale member, a middle sandstone member, and an upper shale member. The shales are organic-rich and of marine origin. They are rich source rocks for oil and natural gas. All three members of the Bakken Formation have been known to yield oil and natural gas. Akata Formation. The Akata Formation is Paleocene in age. It is composed of thick shales, turbidite sands, and small amounts of silt and clay. The clay content resulted in it being a ductile shale formation which was squeezed into shale diapirs in the basin. The Akata Formation formed during lowstands in relative sea level and anoxic conditions.

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 …The smallest grains are called clay, then silt, then sand. Grains larger than 2 millimeters are called pebbles. Shale is a rock made mostly of clay, siltstone is made up of silt-sized grains, sandstone is made of sand-sized clasts, and conglomerate is made of pebbles surrounded by a matrix of sand or mud.

A series of more or less sandy shales and clays, of gray or drab color, very similar in character to Mancos shale. Includes, in varying abundance, thin calcareous lenses or concretions of impure limestone.Shale gas production and utilization have dramatically transformed the North American and global natural gas landscape. Shale formations and their associated hydrocarbons have been found to be internationally abundant based on US EIA studies, although extraction largely depends on availability of massive fracturing equipment.

The upper part of the Early Cambrian sand Formation is composed of glauconitic sandstone which is overlain by gray-green siltstones and shale of Middle Cambrian age. Shale is a tightly packed sedimentary rock. The shale is very porous, but it is not very permeable. This allows the shale to hold a lot of oil/natural gas but makes it difficult to remove those energy sources. Recent technologies have made it possible to extract the oil and natural gas trapped in deep shale formations.
