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. Niobrara Formation. According to Hattin (1982), Moore and Hays (1917) were the first to regard the Kansas Niobrara as a formation, and the first to give member status to the currently recognized divisions; the Fort Hays Limestone Member and the Smoky Hill Chalk Member. Russell (1967) reviewed the specimens collected by the 1871 Yale ex-For example, Eze-Aku Shale is similar to Barnett Shale, Horn River Shale, Niobrara Shale Formation, and Chattanooga/Woodford in silica-richness, whilst showing a similar volume of calcite and relatively lesser amounts of clay minerals than the Eagle Ford Shale (Green River) and Haynesville (Fig. 7 and Table 6). Correlation parameters vary ...

With an abundance of horizontal activityThe Niobrara Formation records life at the heyday of this seaway, from 87 to 82 million years ago between the Coniacian and the Campanian Stages of the Late Cretaceous. Prior to the Niobrara was the rather poorer Dakota Formation and after that comes the Pierre Shale. Contemporaries to Niobrara include the Mooreville Chalk of Alabama.Shale gas reservoirs, with typically ultra-low permeabilities, have been a major focus of hydrocarbon production over the past few decades. In this paper, we investigated how biogeomechanical alteration of near-wellbore properties could potentially impact hydrocarbon recovery from low-permeability reservoirs, using Wolfcamp shale and Niobrara shale …

The Pierre shale is underlain by the Niobrara limestone, but this formation does not reach the surface in the portion of Nebraska west of the one hundred and third meridian. As, however, it would be reached by deep borings for artesian water, some of its characteristics should be pointed out. Its thickness is about 50 feet.
