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. Oil and natural gas can be found deep below the earth's surface at depths of 300014,000.The Benton Shale (also Benton Formation or Benton Group) is a geologic formation name historically used in Montana, Wyoming, North Dakota, South Dakota, Colorado, Kansas, and Nebraska. In the "mile high" plains in the center of the continent, the named layers preserve marine fossils from the Late Cretaceous Period.The term Benton Limestone has also …The Niobrara formation is a very porous, poorly consolidated micrite. Its high porosity and fracture permeability contributes to its fairly low rock embedment strength and its tendency toward fluid imbibition. A moderately high clay content is also evident (Table 1).Horizontal drilling and artificial stimulation have made the Cretaceous Niobrara Formation, Denver-Julesburg Basin, a prolific, self-sourced, unconventional reservoir that yields both gas and liquids. 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 ...
