The Niobrara formation in the Rocky Mountains/Great Plains region serves as a classic model in research, exploration, production, and development programs involving unconventional reservoirs and source-rock systems. Numerous geologic and geochemical studies of the organic and inorganic constituents within the chalk of the Upper Cretaceous Niobrara formation, as well as other chalks and associated units, have identified several depositional and diagenetic relationships, giving explorationists more insight into reservoir properties and hydrocarbon maturity in a particular area of interest. The identification and understanding of the geologic, geophysical, and engineering aspects of these chalks have helped develop the Niobrara into a major play area in the Rocky Mountains/Great Plains region. Geologists, reviewing the area's (1) structural relationships and hydrocarbon distribution, (2) reservoir parameters, (3) production technology and log evaluation, (4) fracture stimulation and production characteristics, and (5) exploration models and resource potential, predict that the Niobrara is a highly promising hydrocarbon reservoir/source-rock system that will make a significant contribution to the energy resources of the Denver basin and adjacent areas.
