abandoned, in Las Animas County, Colorado, produced 1.5 BCFG from the Cretaceous Pierre Formation and Apishipa Member of the Niobrara Formation between 1896 and 1943. Natural gas was produced from the Dakota and Morrison Formations in the now- abandoned Wagon Mound field in Mora County, New Mexico.Niobrara Formation (Upper Cretaceous) at surface, covers < 0.1 % of this area. White to dark-gray argillaceous chalk, marl, and shale. Weathers yellow to orange. Contains thin, laterally continuous bentonite beds, chalky carbonaceous shale, minor sand, and small concretions. Thickness up to 150 ft (46 m).Geologic Formations. Cracked Cliffs. NPS photo. The geography of the present Niobrara River valley is closely tied to the Sandhills of Nebraska. Geologists estimate that deposition began about 98 million years ago, when marine seas once covered the area.

The Niobrara Formation is an alternating calcareous chalk/marl system, biologically defined by fecal pellets and robust foraminifers including Heterohelix globulosa, Globigerinelloides ultramicrus ...Niobrara Formation (KS) Niobrara Formation (Smoky Hill Member) (KS) Unknown Stage Niobrara Formation (Smoky Hill Mbr) (KS) Pteranodon longiceps from the Late Cretaceous Niobrara Fm. of Gove County, Kansas (YPM VP 001177). Maps for this species are currently unavailable. Please check back later.The formation overlies the Upper Cretaceous Niobrara Formation and is unconformably overlain by the Paleocene and Eocene Coalmont Formation. The Pierre Shale, which consists of an upper sandy member and a lower shaly member, is primarily marine in origin; however, the sandy member includes minor amounts of coal.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.

The Niobrara Formation is lacking in maturity with low transformation ratio (0.0075-0.035) and extremely low amounts of expelled oil (0.006-0.008 Mtons). We expected these results given the immature T max values from Rock Eval (Fig. 10). However, modeling was required to fully understand the current state of hydrocarbon generation in the ...ABSTRACT Collaborative Research: Integrating Radioisotopic and Astronomical Time Scales for the Cretaceous PIs: Brad Singer, Steve Meyers, Brad Sageman The Cretaceous period, between about 146 and 66 million years ago, was a time of sustained global warming during which atmospheric CO2 levels likely surpassed 800 part per million, similar to the amount predicted for 2100 by ?business-as-usual ... ….

Summary The gas producing section of the Niobrara formation is a low pressure, low permeability chalk. To evaluate the potential of this tight gas reserve, reservoir data were obtained in a systematic program. These data demonstrate that many Niobrara wells can be produced profitably when stimulated by hydraulic fracturing and that an economically optimal fracture treatment can be designed.period, particularly for horizonal drilling of the Niobrara Shale formation. The Mowry Shale is an organic-rich play and indicates a promising potential based on other shale play analogs. Exploration of the Mowry was delayed due to the 2015 downturn, therefore limited production data is available today.

Abstract. The Mancos-Niobrara formation in western Colorado is estimated by the USGS to contain 66 trillion cubic feet of natural gas. Successfully developing this asset depends on understanding the geology, geomechanics, the impact of fracture length and height, conductivity, fracture spacing, and well spacing on estimated ultimate recovery. The Mancos-Niobrara has tremendous resource ...Its type locality is Hackberry Creek Valley, which is in a Santonian/Campanian offshore horizon in the Niobrara Formation of Kansas. Fossilworks hosts query, analysis, and download functions used to access large paleontological data sets. It presents taxonomic, distributional, and ecological data about the entire fossil record.Marked cycles in color, carbonate and organic-carbon concentrations, geophysical log characteristics (for example, gamma-ray and sonic velocity), degree of bioturbation, and composition of benthic faunal assemblages characterize the pelagic carbonate sequences of the Upper Cretaceous Niobrara Formation in the Cretaceous Western Interior Seaway ofNorth America and seem to be attributable to ...
