Niobrara formation.

The Niobrara Formation, also called the Niobrara Chalk is a geologic formation in North America that was laid down between 87 and 82 million years ago during the Coniacian, Santonian, and Campanian ages of the Late Cretaceous. It is composed of two structural units, the Smoky Hill Chalk Member overlying the Fort Hays Limestone Member. The chalk formed from the accumulation of coccoliths from ...This data release contains the boundaries of assessment units and input data for the assessment of continuous oil and gas resources of the Niobrara interval of the Cody Shale in the Bighorn Basin Province of Wyoming and Montana.

A recent U.S. Geological Survey (USGS) oil and gas assessment of the Powder River Basin , Wyoming and Montana, identified the Upper Cretaceous Mowry Shale and Niobrara Formation as the primary hydrocarbon sources for Cretaceous conventional and unconventional reservoirs.

The Niobrara Shale is a name given to a large shale rock formation, part of which resides in Northeast Colorado. Oil and natural gas are found deep below this rock formation, at depths of 3,000 to 14,000 feet. Mining companies routinely drill vertical and horizontal wells to get to the oil and gas in the Niobrara formation.and underlying Niobrara Formation near the town of Presho, SD in 2014-15.

Much of Colorado oil and gas development, including in the prolific Wattenberg field, has been just north of Denver in Weld County, but the area north of there has been drawing increased interest in recent years.

It is an Upper Cretaceous formation in the Rockies region that consists of a combination of chalk and marl layers, as presented in Fig. 16.1B. The organic-rich marls within the Niobrara Formation act as source rocks, whereas the chalks and clay-rich limestones act as the reservoir formations (ElGhonimy, 2015, Finn and Johnson, 2005).
