In the Niobrara play, a subsurface structure map on top of the Niobrara formation is a first step to locate areas of maximum bed curvature. Normal faults should then be mapped from subsurface well control, photogeology, and good old-fashioned field work. Cross-linears may be mapped from photogeology and satellite imagery. Below is an example Niobrara structure map.
