The Niobrara Formation consists of up to 750 feet of chalk. The outcrop belt trends southwest from north-central Kansas. The Fort Hays Member is a light-gray to very light-yellow chalk; it is massively bedded and has thin, light to dark-gray, chalky-clay partings. The Fort Hays Member forms up to the basal 90 feet of the Niobrara Formation. When it comes to job searching, having a great resume is key. A resume is your first impression to potential employers, and it’s important to make sure that you’re presenting yourself in the best possible light.

Hydrocarbon fluids from the two units are commingled in producing wells, and the combined interval is referred to as the Codell-Niobrara interval in this report. Porosity of the Codell, determined from density logs, ranges from less than 8-22 percent. TheThe 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.Media in category "Niobrara Formation".

Inoceramids are an extinct group of bivalves (clams) that grew to enormous sizes (several feet across) during the Cretaceous. They were well-adapted to many different marine environments from shallow to deep waters. In Nebraska, they are very common in the Greenhorn Limestone and the Niobrara Formation.The Niobrara Formation ranges in thickness up to about 450 ft (Burchett, 1992) in the play area. The principal reservoir for gas is the upper 10–45 ft of the Smoky Hill Member of the Niobrara Formation. Depths of production range from 1,500 ft (Beecher Island field) to more than 2,900 ft (White Eagle field).The boundary between the Carlile and Niobrara formations is recognized at a distinct zone (3 to 15 m thick) of 17 bentonites in the lower part of the Niobrara Formation, whereof two are argon ...The aim of this research study is to understand the physico-chemical interactions between fracturing fluid and formation to investigate the associated geomechanical property changes taking place in the Niobrara shale, a calcium carbonate rich formation, during and after hydraulic fracturing treatments.The Niobrara Formation, also called Niobrara Chalk, is a geologic formation in North America that was laid down between 87 and 82 million years ago during the late Cretaceous period.
