Median dissolved solids, Se, and U concentrations in Niobrara-influenced inflows were 288%, 863%, and 155%, respectively, greater than median concentrations where the Niobrara Formation was absent. Identification of the Niobrara Formation as a disproportionate source for dissolved solids, Se, and U will allow for more targeted studies and ...The Niobrara shale is an organic-rich source rock in the Denver-Julesberg (DJ) basin. Although it is in the early stages of exploration and development, the Niobrara is being compared to the Eagleford shale and the Bakken shale, in a geologic and reservoir context. At the Cemex quarry, the over-sized van was a great place for a poster ...The Niobrara Formation (latest Turonian to earliest Campanian in age) in Manitoba is up to 73 m thick and consists of a lower calcareous shale succession overlain by chalky shale. A local to regional unconformity exists between the Niobrara and the overlying Pierre Formation; the break is less pronounced to the west (North and Caldwell, 1975 ...

Recently, 3D seismic data in the Denver Basin has helped identify a polygonal fault system within the Niobrara Formation. Polygonal faults are layer bound extensional features that develop in fine-grained rocks. Faults observed in outcrop were related to faults interpreted on seismic over the Wattenberg and Silo fields of Colorado. We interpret ...Named as top formation of Lower Cretaceous series, top of Lower Cretaceous. Formerly called "formation No. 3" (Meek and Hayden, 1857). Type not designated. Named for Niobrara River, Knox Co, NE in Salina basin, where formation forms 90-100 ft cliffs near mouth along Missouri River.Niobrara State Park is located in northern Nebraska along the border with South Dakota. At this park, excellent exposures of the Niobrara Formation can be observed on the trails along the river. Near the entrance of the park, thick exposures of dark gray/black Pierre Shale can be seen.ABSTRACT. This paper presents geologic and reservoir parameters of the Niobrara Formation in Weld County, Colorado. With the use of computer generated contour maps, it is possible to predict favorable areas of profitable Niobrara pay. This predictability is further enhanced when combined with Scanning Electron Microscopy (SEM) analysis and historical production analysis.The SEM results show ...

Fracturing fluid leak-off and imbibition are known to cause various forms of formation damage during the fracturing operations such as clay swelling (Zhou et al. 2014; Eveline et al. 2016), fines migration (Conway et al. 2011), and aqueous trapping (Zhong et al. 2015).Besides altering the permeability, the interaction between the fracturing fluid …Benton formation. Recognized in subsurface of Williston basin, northwestern and central South Dakota. Conformably underlies Dakota sandstone and conformably overlies Niobrara formation. Correlates with (ascending) Graneros, Greenhorn, and Carlile formations of Ward County, north-central North Dakota.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). Maquoketa Formation or Group (Upper Ordovician (Stage 6 to Hirnatian)) at surface, covers < 0.1 % of this area.

Pg. 2183-2187, 2197 (fig. 2). Greenhorn formation. Formations in Black Hills that are equivalent to Colorado shale of central and northwestern Montana are (ascending) Fall River sandstone, Skull Creek shale, Newcastle sandstone, Mowry shale, Belle Fourche shale, Greenhorn formation, Carlile shale, and Niobrara formation.Protostega is an extinct genus of turtle that lived in North America during the Late Cretaceous. Protostega is the second largest turtle that ever existed, being 3 meters (9.8 feet) long, only beat by Archelon and longer than Stupendemys. Protostega's shell lacked ossification, which helped bring the animal down in weight and streamline it for open …

2010 jeep liberty for sale The targets are the Late Cretaceous Steele Shale and the Niobrara Formation, having a combined thickness of 3700-4900 ft. The productive intervals have a depth ranging from 8500 to 13,000 ft ...Name applied as the basal member of the Niobrara Formation to a 40 ft thick gray hard limestone above the Carlile Shale and beneath the Smoky Hill Shale Member of the Niobrara. Occurs in the Pueblo area, Pueblo Co, CO in the Denver basin as 40 layers of limestone, 1-26 inches thick, separated by gray calcareous shale. riley jefferswhat is natural consequences which was also recovered from the Niobrara Formation. The new species consists of an extended anterior spike-like rhachis and a greatly enlarged ventrally open posterior conus. Niobrarateuthis walkeri n. sp. inhabited the Niobrara Sea during late Coniacian to early Santonian time and was recovered from the basal Smoky Hill Chalk. INTRODUCTION countries next to cuba Hierosaurus (meaning "sacred lizard") is an extinct genus of nodosaurid ankylosaur which lived during the Late Cretaceous 87 to 82 million years ago. Its fossils were found in the Smoky Hill Chalk Member of the Niobrara Formation, in western Kansas, which would have been near the middle of the Western Interior Sea during the Late Cretaceous.This chapter discusses the chalk reservoirs. Chalk is a friable, fine-textured limestone composed dominantly of coccoliths, but in which pelagic foraminifera also occur. Coccoliths accumulate initially as oozes, and later become chalk when lithified. The Upper Cretaceous Chalk, for example, which is 200-400 m or more in thickness, is so ... shale descriptionking agu onlyfansnuclear silos in kansas Black shales within the Niobrara Formation, some of which are rich in coccoliths* and fecal pellets, are the major hydrocarbon source rocks; shaly beds that overlie the chalky or sandy reservoir intervals are seals (Longman and others, 1998). Organic richness (TOC) in source intervals ranges from less than 1 percent in the siliciclastic-rich ... mary stuckey The contact between the Carlile Shale and the overlying Niobrara Formation is marked by an unconformity in much of the outcrop area, but where an unconformity is not discernible, the boundary is typically placed at the first resistant, fine-grained limestone bed at the base of the Niobrara Formation.
