... in the Denver Basin the Beecher Island zone is known informally as the A Chalk or the Upper Chalk. A stratigraphic column for the Paleozoic and Mesozoic sections is also included (Figure 2). Permian salt dissolution creates low amplitude structures in Yuma County and the source of the water for salt...

.... The reservoir is thick (75 to 175 feet in our target area). Seals are evaporitic above and shaly below. Reservoir heterogeneity is minor compared to other reservoirs. Introduction The Denver Basin is a large asymmetrical basin formed during the Laramide Orogeny (Figure 1). The basin has a gentle dipping...

... gas and oil to determine the origin of the hydrocarbon stored in different Cretaceous intervals from Denver basin and their production equivalent phases. Geochemistry data were generated from cored rocks, cuttings, mud gas, extracted oils and compared with the produced gas and oils from the Denver...

... Abstract This investigation reviews the vertical distribution of organic-rich sequences in Upper Cretaceous rocks of the northern Denver Basin. The primary objective is to provide a more complete definition of the effective source rocks in this sequence. Multiple organic-rich members...

... Abstract 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...

... Abstract The Niobrara Formation and Codell Sandstone are important producers in the East Pony and Redtail areas of the Denver Basin. These formations are currently being developed with horizontal drilling and multi-stage hydraulic fracturing. Many geological and technological factors influence...

... in the Denver Basin. A dataset comprised of fracture plane orientations and fracture intensity variations was acquired at the Niobrara outcrop. The study identified two major joint sets and two conjugate shear fracture sets. Local tectonic variations (such as listric faults in the negative flower structures...

... Abstract The Niobrara Formation consists of deep-water chalks and marl units in the Denver Basin. Chalk units are generally considered the reservoir rock while the marls contain higher total organic carbon (TOC) contents and are considered the source beds. Chalk and marl units consist...

... Abstract The Upper Cretaceous Codell Sandstone is a major pay in the giant Wattenberg Field of the Denver Basin. Vertical well completions in the Codell date back to 1981 and were hydraulic fracture stimulated. The vertical wells also have a history of successful hydraulic refracturing. New...

... The Codell Sandstone is a low-resistivity, low-contrast pay in parts of the northern Denver Basin. The area of new oil and gas production is in the deeper part of the basin between the Silo and Wattenberg fields of Wyoming and Colorado, respectively. Thickness of the Codell averages 15 to 20 ft...

... Silo Field, located in the northern Denver Basin, is an important field for Niobrara oil production. The production is heavily controlled by the presence of open, vertical, natural fractures but the genesis of these features is not understood. A 3-D seismic survey, covering approximately 30...

The Niobrara is overpressured and drilling depths are 6200 to 7800 ft. The Wattenberg area is a " hot spot" or positive...
