Organic-rich beds in the formation have organic carbon values which range from 0.5 to 8 weight percent and average 3.2 weight percent. The kerogen present in the Niobrara is Type-II or oil-prone (sapropelic).The Niobrara Formation in the Denver Basin is an unconventional oil and gas play composed of highly cyclic, alternating chalk and marl units. These units act as the source, seal and trap for hydrocarbons generated in the organic rich marl beds of the Niobrara. The organic-rich marls act as source rocks and represent periods of anoxia and ...The Niobrara Formation (often called the Niobrara Chalk) was deposited during the Late Cretaceous about 80-88 million years ago.
