The Kansas Niobrara Cretaceous ... At several places in the upper part of the formation there occur thin seams filled with fragments of bones, scales, teeth and similar remains much broken up and comminuted. No coal, of any character has ever been discovered in the formation, and from the nature of the beds can not be expected. ...Calibrated petrophysical model for elevated organic matter intervals and mineralogical variability in the Agrio Formation, Neuquén Basin, Argentina. Raul I. Ochoa, Lauren P. Birgenheier, Ernesto Schwarz, Jesús M. Salazar. Article 105913.The formation also crops out along Sappa Creek, in Decatur and Norton counties, and along Prairie Dog Creek in Norton and Phillips counties, as southwestward extensions of the Nebraska Niobrara outcrop (Fig. 1). Altogether, the Niobrara crops out in parts of 23 Kansas counties (Fig. 1).The Niobrara Formation Strata of the Niobrara Formation were originally documented by Meek and Hayden (1861) for exposures near the confl uence of the Niobrara and Missouri Rivers in Nebraska and described as consisting of calcareous marl with chalk and limestone. The interval was later divided by Logan (1897) into lower Fort

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 total organic-carbon-rich marl beds of the Niobrara.Formation No. 3--Niobrara; Formation No. 2--Fort Benton; Formation No. 1--Dakota; Cretaceous rocks were mapped in Kansas as early as 1857 (Hayden) but detailed study proceeded slowly as evident in a remark by Swallow (1866, p. 10), in his first annual report as State Geologist of Kansas, that the "...Its type locality is FHSM VP-2295 locality, Ellis County, which is in a Coniacian marine chalk in the Niobrara Formation of Kansas. Ecology: aquatic carnivore. Fossilworks hosts query, analysis, and download functions used to access large paleontological data sets. It presents taxonomic, distributional, and ecological data about the entire ...A data set of 200 well production data and completion designs was collected from oil production wells in the Niobrara shale formation. Artificial neural network (ANN) and random forest (RF) techniques were implemented to predict EUR from the completion design. The results showed a low accuracy of direct prediction of the EUR from the completion ...Geosternbergia is an extinct pteranodontid - pterodactyloid pterosaur from the Late Cretaceous geological period of North America. It was one of the largest pterosaur genera and had a wingspan of up to 7.25 meters (23.8 feet). Geosternbergia was among the largest pterosaurs, with the wingspan of most adults ranging between 3–6 meters …

This study presents a regional stratigraphic framework and paleoenvironmental reconstruction of the Niobrara Formation in northern Colorado (Fig. 1) based upon multidisciplinary biostratigraphic and petrographic data.In doing so, this analysis provides an integrated biofacies/lithofacies model of sediment deposition and regional paleoenvironments that will assist in reservoir characterization ...2. Pierre Formation and Niobrara Formation. Pierre and Niobrara are the lowest (or earliest) layers exposed in North Dakota. Some of the Pierre can be seen in extreme southwestern North Dakota. The Pierre and the … ….

The field was previously studied in order to understand the petroleum potential of the Frontier Formation.Type specimen: KUVP 1209, a partial skeleton (plastron, twelve marginalia, two or three neuralia, and portions of two costal plates). Its type locality is Niobrara, which is in a Senonian marine chalk in the Niobrara Formation of Kansas. Ecology: Environments: carbonate (3 collections), marine (1) Age range: 85.8 to 84.9 Ma. Distribution:

The Fort Hays limestone is the lower member of the Niobrara formation (Moore, Frye, and Jewett, 1944, p. 152) of Cretaceous age. The Fort Hays member is recognized in the field primarily by its thick massive beds and small amount of shale. Chalky shale is the major constituent of the overlying Smoky Hill chalk.The Pierre Shale is underlain by the calcareous Niobrara Formation and overlain by the Fox Hills Sandstone. Both contacts are conformable and transitional. The base of the Pierre is at the top of a persistent orange-weathering chalk bed that forms a hogback at the top of the Smoky Hill Shale Member of the Niobrara Formation.

best western smoking rooms The productive Niobrara Formation in the basin contains calcareous shale, shaley limestone, and marls as reservoir rocks. According the USGS, reservoir zones in the Niobrara range from 50 to 200 feet in thickness, however, there have been wells drilled in the basin where the zones were near 400 feet. The most prolific benches composed of these ...The samples from the Niobrara Formation have T max values ranging from 419 to 427 °C with an average of 423 °C. Geochemistry. The generative potential for hydrocarbons is estimated based on total pyrolyzable organic carbon content (TOC), thermal maturity, and kerogen type (Hood et al., 1975). Cuttings are often viewed as potentially ... international student servicesad astra recovery services inc 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. Similar to the Greenhorn Limestone, the ...Gladius of the species Euchoteuthis melanae, from the Cretaceous Niobrara Formation of Wichita County, Kansas.
