Niobrara and Greenhorn Formations Geological and Petrophysical Database for the DJ and Raton Basins
Available August 2011!
This three-part study covers the DJ basin Niobrara and Greenhorn tight oil plays from SE Wyoming to the New Mexico border. The objective of the project is to provide a regional framework with the data needed to quickly extend your mapping across the entire play fairway; to provide completed regional maps and sections for screening lease acquisition and drilling opportunities; and to build an immediately workable dataset to give new entrants a head start on their geologic evaluations.

Phase I-Complete, to be delivered in early August 2011
Covers the northern DJ basin play fairway from the city of Denver north into Wyoming.

Phase II-Complete, in confidential holding until December 2011
Covers the southern Colorado portion of the DJ basin and the Raton basin.

Phase III-In progress, anticipated completion in 1st Quarter 2012
A detailed vitrinite reflectance and thermal maturation evaluation of the entire play incorporating new sampling of >200 representative wells.
