Niobrara formation
This paper clarifies the controls of oil retention in the Niobrara Formation, Denver Basin, in the western United States. Sweet spots have been recognized using a total of 98 core samples from 5 wells with maturities covering the oil window.Niobrara Formation (Upper Cretaceous) at surface, covers < 0.1 % of this area. White to dark-gray argillaceous chalk, marl, and shale. Weathers yellow to orange. Contains thin, laterally continuous bentonite beds, chalky carbonaceous shale, minor sand, and small concretions. Thickness up to 150 ft (46 m).In southern New Mexico the Niobrara equivalent is assigned to the Mesa Verde Formation (or Group) (Cobban and Reeside, 1952, chart lOb). In western Colorado the Niobrara passes into calcareous beds of the Mancos Shale (Fisher and others, 1960) and in east-central Utah is represented by the Bluegate Shale Tongue of the Mancos (McGookey and ...

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 ...Gladius of species Kansasteuthis lindneri from the Cretaceous Niobrara Formation of Rooks County, Kansas.

Production is from the fractured Niobrara Formation at depths ranging from 7,600 to 8,500 ft (2,318 to 2,593 m). Cumulative production from 40 vertical wells at Silo is in excess of 1.3 million bbl of oil. Two wells have produced 437,000 bbl of oil. Texas's Midland Basin accounted for 15% of U.S. crude oil production in 2020. EIA estimates drilled but uncompleted wells for key oil and natural gas basins. U.S. crude oil and natural gas production in 2019 hit records with fewer rigs and wells.
