... of imbibition rate, diffusion coefficient, pore connectivity and distribution were achieved from samples of drill cuttings and core plug across different rock units of Niobrara formation. The research consists of three methodologies which include laboratory experiments of pore structure characterization, gas...

... of this study is to analyze Niobrara structures in Eastern Colorado with regard to origin of the structures, timing of structural growth, and biogenic gas formation and accumulation. Fields in Yuma County produce dominantly methane-rich gas from the Cretaceous Niobrara Formation. Niobrara gas production...

... Abstract The Powder River Basin (PRB) unconventional source rock play in Upper Cretaceous Niobrara Formation is exploits up to four different landing zones, although well spacing and field development are still being optimized. Wine rack development can be improved with an understanding...

... 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...

... unconventional reservoir challenges. This procedure integrates petrophysics, rock typing, 3D seismic elastic properties, and geostatistics to build the reservoir model, and then directly incorporates the reservoir results into fracture model designs. This methodology was used on the Cretaceous Niobrara formation...

... on the water surface in the reactor during heating. The chalk and marlstone sequence of the Cretaceous Niobrara Formation in the Denver Basin provides an excellent test of this approach with both lithologies being a source and reservoir of retained oil to different degrees. complex reservoir low...

... Summary The presence of natural fractures is an important attribute of an unconventional reservoir. The purpose of this study was to characterize the fracture patterns and to determine the drivers that influenced fracture distributions within the Niobrara Formation, a major resource play...

... 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 operator has drilled and completed a number of 8,000 to 10,000 foot horizontal wells in the Niobrara Formation in the Piceance Basin in Colorado. The Niobrara Formation in the Piceance Basin is a 1,200 foot thick gas-producing pay-zone of complex rock properties with (35% to 65...

... Summary Unconventional reservoirs are multivariate problems requiring integration of data across multiple disciplines. Microseismic data recording hydraulic fracture treatments in the Niobrara Formation in the Denver Basin are no exception. Microseismic data are the real time recording...

... Summary The Codell Sandstone has recently been the subject of extensive exploration and subsequent development activity in both the Colorado and Wyoming portions of northern DJ Basin. The Niobrara Formation has been the primary historical exploration target since the late 1980's due to success...

... Summary The organic-rich marls within the Niobrara Formation act as source rocks while the chalks act as reservoirs. The hydrocarbon potential of a source rock is highly dependent on its organic content and maturity. Different empirical relationships were developed to estimate TOC from logs...
