• The Niobrara is areally extensive in northeastern Colorado and adjacent states.  
    • Thermal history parallels GOR trends.  
  • Traditional petrophysical workflows, with added rigor where needed, will allow full scale reservoir evaluation. 
    • There is a correlation between geologic rock types and log response.  
  • Conventional stratigraphic nomenclature does not always relate to subsurface rock properties. 
  • 3D seismic decreases operations and targeting risk. 
    • Opportunities for dynamic geosteering. 
    • Static and dynamic reservoir modeling.  
  • Integrated data gathering resulted in increased OOIP estimates and actual recovery.
