Fault, fracture, and geomechanical analysis of the Niobrara Formation, Wattenberg field, ColoradoMedian dissolved solids, Se, and U concentrations in Niobrara-influenced inflows were 288%, 863%, and 155%, respectively, greater than median concentrations where the Niobrara Formation was absent. Identification of the Niobrara Formation as a disproportionate source for dissolved solids, Se, and U will allow for more targeted studies and ...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. It is about 600 feet thick and is composed of two structural units, the Smoky Hill Chalk Member that overlies the Fort Hayes Limestone Member.Some of the most notable outcrops are the Monument Rocks of Western Kansas, that are comprised of the Smokey Hills Chalk of the larger Niobrara Formation.

ABSTRACT. This paper presents geologic and reservoir parameters of the Niobrara Formation in Weld County, Colorado. With the use of computer generated contour maps, it is possible to predict favorable areas of profitable Niobrara pay. This predictability is further enhanced when combined with Scanning Electron Microscopy (SEM) analysis and historical production analysis.The SEM results show ...7 jan. 2013 ...

Figure 3.The Niobrara Formation is formally sub-divided into two members: the Fort Hays Limestone and the Smoky Hill Chalk. The basal Fort Hays Limestone is relatively organic-carbon poor and consists of ledge-forming limestone beds separated by thin shales (Scott and Cobban, 1964).
