... to create either fault plane or fault stick interpretations in a standard interpretation package. The SOM is preceded by principal component analysis to identify prominent attributes. These resolve the seismic character of the analysis interval (Top Niobrara to Top Greenhorn). In addition to enhanced fault...

... Abstract Understanding how and why fluids move in the subsurface is key to characterizing and most efficiently developing an operator's acreage. In the DJ Basin, oil from the Niobrara and Codell likely has a common source and their reservoirs are likely in communication with each other. Great...

..., Colorado is the focus area for descriptions provided by samples available from the Niobrara, Carlile, Greenhorn and Graneros intervals. A review of rock extract and produced oil geochemical data made available by operators reveals discrete geochemical signatures among organic rich source rocks...

... Abstract The Cretaceous reservoirs of the Rockies have become an important component of future unconventional oil growth in the lower 48. Horizontal drilling within the Powder River Basin (PRB), is moving from appraisal towards co-development of horizontal targets within the Niobrara and Turner...

... detailed petrophysical characterization. In a pilot study, two extended reach laterals, one Niobrara C well and one Codell well, were drilled in 2017, with samples collected every 100 feet and tested for energy-dispersive X-ray Fluorescence (ED_XRF), bulk X-ray Diffraction (XRD), and HAWK Pyrolysis...

... of the Niobrara and Codell formations, the primary targets for development in this portion of the basin. The seismic data are from Phase 5 of the GPI/Fairfield Niobrara program in northern Colorado. A preliminary workflow which included synthetics, horizon picking and correlation of 28 wells was completed...

... unconventional development has been limited thus far, the stacked potential of the Cretaceous section has become an intriguing prospect as the oil market recovers. Cretaceous unconventional targets in the PRB include two main source-rock intervals, the Mowry Shale and the Niobrara Formation, as well as tight...

... Abstract The Niobrara interval in the Denver-Julesberg (DJ) Basin contains several important unconventional hydrocarbon targets. However, the Niobrara is extensively faulted, which poses challenges for accurately landing and steering laterals in zone. Insight into small faulted structures...

... on the seismic sections where they cut across the Niobrara at 30 – 45°. Wells that pass above, below, or intersect the faults at high angles are generally drilled and completed without issue. At deeper levels, wells intersected the same faults at very low angles (where fault dips < 30°) and experienced...

.... Sample collection is simple and does not require specialized equipment or operational downtime. 80 horizontal, hydraulically fractured wells completed in the Cretaceous Niobrara or Codell Formations were selected for this study. More than 1,500 samples were collected and analyzed in total, including...

This paper discusses a detailed approach to investigating well-to-well interference based on integrating hydraulic fracture modeling and reservoir simulation in two different formations, the Niobrara and Codell, in the Denver-Julesburg Basin. The geomechanical properties were calibrated by DFIT data...

... 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...

... are targeted through horizontal drilling – the Niobrara (A-C Chalks) and Codell formations. The Niobrara consists of alternating chalk and marl units, whereas the Codell Formation consists of a clay-rich sandstone; both were deposited within the Interior Cretaceous Seaway.
