Pierre shale.

Roads and structures built on Pierre Shale hillsides often slump as the shale becomes wet. The unit produces a variety of marine vertebrate fossils including fish, mosasaurs and plesiosaurs. Kn: Cretaceous, Niobrara Formation, 80-88 million years old The Niobrara Formation is composed predominantly of grey to yellow chalk and chalky shale.USGS Publications Warehouse. The Pierre Shale and equivalent rocks of Late Cretaceous age consist in the east-central Dakotas of several hundred feet of offshore-marine shale and minor marl; in west-central Montana near the sediment source the equivalents of the Pierre Shale consist of several thousand feet of volcanic-rich and mostly nonmarine ...Black opaline spiculite, gray to black shale, yellow-brown to gray chalk, gray silty clay, and pink quartz-rich sandstone. Includes the Split Rock Creek Formation and other near-shore facies of the Dakota Formation, Graneros Shale, Greenhorn Formation, Carlile Shale, Niobrara Formation, and Pierre Shale. Thickness up to 400 ft (122 m).The Pierre Shale, by far the thickest formation in the quadrangle, is easily eroded and poorly exposed, although a part of the Hygiene Sandstone Member, in the middle part of the formation, locally forms a hog­ back.

A computer scan of the "Well History Control System", produced by the Petroleum Infor­ mation Corporation, selected one well per township from the 33,000 wells which penetrated the Pierre. The resulting sample of 5,000 control pointsThe modeling uses the Fourier method to compute the spatial derivatives, and therefore can handle complex geometries and general material-property variability. I verified the results by comparison with the 2D analytical solution obtained for wave propagation in homogeneous Pierre Shale.Pierre Shale (Upper Cretaceous) at surface, covers 55 % of this area. Blue-gray to dark-gray, fissile to blocky shale with persistent beds of bentonite, black organic shale, and light-brown chalky shale. Contains minor sandstone, conglomerate, and abundant carbonate and ferruginous concretions. Thickness up to 1,000 ft (305 m).In the Pierre Shale Sandstones play, oil and gas is produced from the Sussex and Shannon sandstones. These reservoirs reach 4,500' to 5000' in depth and range from 3'- 50' in thickness. and include seven accumulations. Shale and shallow chalk reservoirs of the Upper Cretaceous Niobrara formation house dry non-associated gas.

The Pierre Shale has the highest CEC, approximately 40 meq/100 g, consistent with its large clay mineral content composed primarily of mixed layer illite/smectite. This value is consistent with the reported range of observed CEC values for the Pierre Shale in the literature (30-50 meq/100 g; Schultz et al., 1980). Samples GOM-14 and GOM-17 ...

The Pierre shale was checked every day for 30 days and then at the end of each month for 6 months, and finally once a year for 3 years. Optimum moisture and standard Proctor density measurements were made for each untreated soil, and for each of the lime contents which had been used for the pH deter­ minations.

loess and the weathered Pierre Shale. Both are a cause of structural damage to foundations. The Pierre is a major source of road and highway engineering problems. The processes of major conse- quence to man are the flooding of the high-gradient streams draining the mountain front, the mass movement ofHowever, in fracking the shale, the mechanism of increased gas production after the prolonged well shut-in has yet to be understood. The objective of this paper is to address this issue. To shed light on this issue we have studied and experimented with Pierre shale in detail. In our experimental work we suspended approximately 15 grams of shale ...The Pierre Shale of Late Cretaceous age forms an impermeable base to the High Plains aquifer in much of Colorado.

Attenuation measurements were made near Limon, Colorado, where the Pierre shale is unusually uniform from depths of less than 100 ft to approximately 4,000 ft. Particle velocity wave forms were measured at distances up to 750 ft from explosive and mechanical sources. Explosives gave a well‐defined compressional pulse which was observed along vertical and horizontal travel paths. A weight ...

The bentonite beds marking the basal Pierre can be seen near the center of the picture. At least 24 separate bentonite beds are exposed in the Pierre Shale from the center to the top of the picture.These values are greater than 0.63 which is a reported B-value for Pierre shale (Makhnenko et al., 2011). The B-value is often used as a measure of the degree of sample saturation. ...Gomez-Gutierrez et al. (2011) conducted slake durability and swell tests on unweathered shales, and the prediction equation is written: (4) S = 29.33 exp ( − 0.064 I d 2 C) where Id2, which as a function of W, is the slake durability index. When shale underground absorbs water, the confined pressure will influence its swelling potential.
