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 ...

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. Gallery The Niobrara Formation was deposited on the erosional surface during the subsequent sea-level rise. The unconformity at the top of the Carlile Formation places the upper portion of the Fort Hays Member of the Niobrara Formation on the Codell Sandstone, or the lower Carlile interval (D, Figure 30). The unconformity has been interpreted by Weimer ...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).High-resolution event stratigraphy of the Niobrara Formation in Colorado at Pueblo and along the northern Colorado Front Range provides a more precise and detailed framework for correlation than traditional lithologic and biostratigraphic methods. Bentonites and shale-limestone bedding couplets can be successfully correlated regionally.2.22 Niobrara Shale. The Niobrara shale formation (Denver-Julesburg Basin, Colorado) is a shale rock formation located in Northeast Colorado, Northwest Kansas, Southwest Nebraska, and Southeast Wyoming.

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 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.
