Oct 1, 2021 · In the Upper Cretaceous Niobrara Formation shale oil play, considerable oil fractions are produced directly from C 14+ bitumen in place (e.g., extractable organic matter). ). This paper provides new insights on the geochemistry and producibility of C 14+ bitumen by integrating the full process of generation, retention, conversion, expulsion, and production, as a whole, in the Niobrara shale ... Underlain by Niobrara formation; overlain by Shannon member. Shows isopach map and correlation of sandstone beds in the upper part of the member in electric-log correlation diagrams.

The Niobrara Formation limey shale facies have had unusually high mud-gas shows. 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.When it comes to applying for a job, having a well-crafted resume is essential.

New 40 Ar/ 39 Ar dates (n=34) have been acquired from Albian to Campanian representing 1000's of sanidine dates. Campanian U-Pb zircon dates, the first for the Late Cretaceous, are from 8 of the 40 Ar/ 39 Ar dated ashes.
