Niobrara formation.

Western Minnesota The Cretaceous rocks in southwestern Minnesota can be correlated with the better-known regional stratigraphy in South Dakota of the Dakota Formation, Graneros Shale, Greenhorn Limestone, Carlile Shale, Niobrara Formation and Pierre Shale (Fig. 3). Figure 3.In the 1990s, a well-preserved mosasaur skull of uncertain identity, which was discovered in an outcrop of the Niobrara Formation in the northwestern part of Ellis County, Kansas in 1968 and cataloged in the Sternberg Museum as FHSM VP-2295, was recognized by multiple authors as being a new species of Tylosaurus. Despite such recognition ...The Pierre Shale is underlain by the Niobrara Formation throughout all of the northern Great Plains and the Niobrara is the target of exten­ sive recent exploration for natural gas. The Pierre is covered by units of Late Cretaceous, Tertiary, and Pleistocene age. It appears that theIn 2005, the remains of the earliest known D. osborni were discovered in the Fort Hays Limestone, Niobrara Formation in Jewell County, Kansas. This is the first record of a polycotylid plesiosaur in this formation. D. bonneri Dolichorhynchops (Trinacromerum) bonneri in the Rocky Mountain Dinosaur Resource Center in Woodland Park, Colorado

The Niobrara Formation at the Wattenberg Field in the Denver-Julesburg basin is a low permeability carbonate reservoir (Figure 1). It continuously exists throughout the entire field. The Niobrara is a sequence of interbedded carbonate and marine shale. The gross thickness varies approximately from 250 to 350 feet.1 oct. 2021 ...

As a carbonate-dominated reservoir, pore networks documented in most other unconventional shale reservoirs are not necessarily analogous. In this study pore system characterization was achieved ...The Niobrara Formation consists of deep-water chalks and marl units in the Denver Basin. Chalk units are generally considered the reservoir rock while the marls contain higher total organic carbon (TOC) contents and are considered the source beds. Chalk and marl units consist of microscopic coccoliths, forams (dominantly pelagic), inoceramus and oyster fossils, kerogen, clay, silt, and fish ...

This is a stunning, 15.5" long fossilized pectoral fin of a large swordfish (Protosphyraena). It was collected from the Cretaceous age Smoky Hill Chalk (Niobrara Formation) in Gove County, Kansas, making this fossil approximately 83 million years old. The preservation of this fin is impressive to say the least, with fine grooves that run ...

Niobrara Formation . The Niobrara Formation (often called the Niobrara Chalk) was deposited during the Late Cretaceous about 80-88 million years ago. This unit is a chalk because it consists mostly of ancient marine plankton. Other marine fossils, including shells and fish bones also have been found in the Niobrara Formation. Texas's Midland Basin accounted for 15% of U.S. crude oil production in 2020. EIA estimates drilled but uncompleted wells for key oil and natural gas basins. U.S. crude oil and natural gas production in 2019 hit records with fewer rigs and wells. U.S. natural gas production efficiency continued to improve in 2019.Interbedded chalky reservoirs and marly source rock within the Niobrara Formation put excellent source rocks adjacent to high porosity, low permeability reservoir intervals. This 350-ft gross source/pay interval is being developed with 1-2 mi long horizontal wellbores in each of the four zones. Four pilot programs determine the well density ...Here is a breakdown of a typical oil and gas well in your area since the inception of horizontal drilling in the Niobrara formation: There have been 8,119 wells drilled in the Niobrara formation with an average daily gas production of 382.37 Mcf per day and oil production of 88.34 barrels per day.The following articles are merged in Scholar.

It presents taxonomic, distributional, and ecological data about the entire ...In addition to the Niobrara Formation, other possible source rocks in the Denver Basin include the Cretaceous Belle Fourche (Graneros), Mowry, and Carlile shales, as well as the Greenhorn Formation. Oil generation in these formations began during the Laramide orogeny and continued through the Miocene (Higley and Cox, 2007).

The Smoky Hill Chalk Member of the Niobrara Chalk was deposited in the Western Interior Sea during a span of about five million years extending from the upper Coniacian through the lower Campanian. Coincidentally, this period also encompasses much of the early evolution and radiation of the family Mosasauridae. Thousands of mosasaur specimens …Niobrara formations, the Codell formation, and the Niobrara formation underlying certain lands, including portions of the Application Lands, with the permitted well locations in accordance with the provisions of Order 407-1. 5.

White (1878) emended this definition to include only the Fort Benton and Niobrara groups.The Niobrara Formation of the Denver Basin is an unconventional oil and gas drilling target composed of alternating chalk and marl units. These units act as the source, seal and trap for hydrocarbons generated in the organic rich marl beds of the Niobrara. Organic geochemical data, such as oil-to-source rock correlations, oil biomarkers and gas ...These badlands are Kansas’ most dramatic Niobrara chalk formation. They provide unique and important habitat for many plants and wildlife. Native amphibians, reptiles and birds such as ferruginous hawks and cliff swallows live here. Little Jerusalem is also home to the largest population of Great Plains wild buckwheat. This is a 15.5" wide cluster of fossil rudists of the species Durania maxima. They come from the Late Cretaceous Niobrara Formation (~83 million years) in Gove County, Kansas. There are a variety of other small marine bivalves scattered across this specimen. Specifically, a large gathering of Pseudoperna congesta oysters.The Niobrara Formation records life at the heyday of this seaway, from 87 to 82 million years ago between the Coniacian and the Campanian Stages of the Late Cretaceous. Prior to the Niobrara was the rather poorer Dakota Formation and after that comes the Pierre Shale. Contemporaries to Niobrara include the Mooreville Chalk of Alabama.

These time-equivalent cycles can be correlated across much of Colorado, Kansas, and northeastern New Mexico by combining subsurface and outcrop data. Documentation of thickness variations within the regionally persistent ...

The Niobrara Formation, one such organic-rich shale, is a particularly hot target here in Colorado. While a large volume of natural gas (>700 billion cubic feet by one estimate) has already been produced, it is now Niobrara oil that is the focus of everyone's attention. Often mentioned for comparison purposes are the Bakken Formation of North ...
