Niobrara formation.

Summary. Since 1981, nearly 1,000 wells have been drilled in the Denver basin of northeastern Colorado with the Codell sandstone as their primary target. The majority of this exploration has been in the axial portion of the basin, in Townships 4 to 7 North, Ranges 64 to 68 West, in Weld and Larimer counties. Drilling depths of Codell wells range from 6,800 to 7,400 ft [2073 to 2256 m].Recently ...The Niobrara Formation (Upper Cretaceous) in the northern Great Plains is being studied by the U.S. Geological Survey because it includes potential low-permeability reservoirs for natural gas.

Niobrara Exploration Controls. Since the Niobrara is a typical low porosity and permeability self sourced oil reservoir formation, there are factors that must be in place for a successful oil well. The key factors in searching for areas of the Niobrara Formation where oil can be produced are ( Sonneberg 2011 ): Niobrara Vitrintie Reflectance ...

The Niobrara Formation consists of up to 750 feet of chalk. The outcrop belt trends southwest from north-central Kansas. The Fort Hays Member is a light-gray to very light-yellow chalk; it is massively bedded and has thin, light to dark-gray, chalky-clay partings. The Fort Hays Member forms up to the basal 90 feet of the Niobrara Formation.
