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.
The Niobrara formation is late Cretaceous in age and was deposited in the Western Interior Seaway (Kaufmann, 1977). The Niobrara is subdivided into basal Fort Hays limestone and Smoky Hill members. The Smoky Hill member is further subdivided into three subunits informally termed Niobrara A, B, and C. These units consist of fractured chalk ...

The Niobrara formation chalks were deposited during the last major transgression of the western interior Cretaceous sea, which extended from the Gulf of Mexico to the Arctic Ocean. The lower member of the Niobrara is the Fort Hays, which is 40 to 85 ft (12 to 25 m) thick. The upper member is the Smoky Hill, which averages 600 ft (180 m) (Fig. 2).The Upper Cretaceous Niobrara Formation in the Denver-Julesburg Basin records late Turonian to early Campanian climate and orbital cycles and tectonic events. The third-order transgressive-regressive events of the Niobrara Cyclothem govern the character of the pelagic and hemipelagic sedimentation of the formation.
