Fumicollis is known from the marine Smoky Hill Member of the Niobrara Formation (upper Coniacian to lower Campanian ) of Kansas (USA) . A combination of features from the vertebrae, pelvis, femur, tibiotarsus, and tarsometatarsus were used to diagnose the genus . These include an elongate preacetabular pelvis, expanded lateral …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. This study will look into and compare the different methods of quantifying TOC from logs and how they ...The B Marl is the most oilprone source rock of the Niobrara Formation. Figure 19 6690' TVD B Marl with abundant bentonite (light p pieces) with trace disseminated pyrite (red arrows). There is also some calcite and fossils (white arrow). In the B Marl, the bentonite is generally devoid of pyrite, or if present it has very fine grained ...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).The Niobrara Formation, one such organic-rich shale, is a particularly hot target here in Colorado. While a large volume of natural gas (>700 billion cubic feet by one estimate) has already been produced, it is now Niobrara oil that is the focus of everyone’s attention. Often mentioned for comparison purposes are the Bakken Formation of North ...The stratigraphy of the Niobrara Formation was described in early. work by Scott and Cobban (1964), where formal and informal. subdivisions were defined.

It has been postulated that this interval may have the potential for high volume of gas reserves from fractured shales, particularly in the Crooks Creek area (Wellborn and Wold, 1993), located to the East of the study area in 27 N-92 W (Fig. 3).Abundant fractures have been encountered in many wells at Antelope Arch.produced from the Niobrara formation in the core parts of the Wattenberg Field and DJ Basin. This result is a considerable improvement on the previous well drilled, the J.W. Powell which recorded an IP of 220 BOE/day. Especially encouraging is the high oil component in the Vespucci well which will deliver a very material boost to revenue.Niobrara Formation.
